Description

The invention relates to a ridge and / or ridge cover and a method for producing a ridge and / or ridge cover, in particular for ridge ventilation, with a ridge or cover cap with at least one inner section and one or more outer sections, the cover cap with Breakthroughs and folding means provided and fixed in the installed state on a ridge and / or ridge slat and arranged below a ridge tile and the outer portion or the outer portions of the cover cap adaptable to the profile of adjacent roofing panels and is or are connected to a first portion , which rests as a support on the ridge and / or ridge batten.

A generic ridge and / or ridge cover is known from DE-GM 92 17 733. The ridge and / or ridge cover described there has a first section Connect section, and an outer section, which is attached to the third section. The first three sections are made of a hard plastic and the outer section of a slightly flexible, bendable and very stretchable material. Each of the sections can be angled relative to the adjacent folds by means of folds running in the longitudinal direction of the cover strip. The cover strip is fastened to a ridge slat or a ridge slat via the first section, bulges with openings are formed in the second section, through which the ventilation takes place, and the third section has projections in the form of support knobs which serve as spacers with respect to the ridge tile, to always ensure a defined gap width between the cover and the inside of the adjacent ridge or ridge cap.

A disadvantage of the known cover is that only the second section has openings for ventilation. On the other hand, in the known cover, the mentioned support knobs on the cap legs are necessary in order to ensure a sufficient flow between the ridge tile and the cover. These rigid support knobs provide a resistance to the air flowing through, which can prevent adequate ventilation, and it is not possible to adapt flexibly to the internal profile of the ridge tile. As a result, a compensation of the step-shaped inner contour of the ridge tile is not sufficiently guaranteed.

The object of the invention is therefore to avoid a ridge and / or ridge cover and a method for producing such, while avoiding the aforementioned disadvantages create that uses the advantages of known ridge and / or ridge cover elements, regardless of the type and design of the roof covering for a more effective ventilation through the ridge area.

According to the invention, the above-mentioned object is achieved by a ridge and / or ridge cover of the type mentioned at the outset in that at least the inner section or sections of the cover cap is or are made of a permanently resiliently deformable material and in that one is located on either side of the first , the middle section and, in relation to the second inner section, which is angled downward, connect the outer section or sections, at least one first outer section bent upward relative to the second inner section being provided with overflow areas, and a third outer section opposite the first outer section angled outwards and a second outer section is arranged as a sealing element in the transition region between the second inner section and the first outer section. A method according to the invention is characterized in that a permanently resiliently deformable material is provided with folding means in the longitudinal direction, whereby several sections are obtained, and is provided by punching with overflow openings, flanges and lamellae and overflow areas, and a second inner section opposite the first, middle section angled and a first outer section is bent upwards relative to the second inner section, a second outer section is arranged in the transition region between the second inner section and the first outer section of the cover cap, and a third outer section is angled outwards relative to the first outer section.

The inventive design, in particular of the outer sections, ensures an inner, non-sealed flow space between the underside or edge of the ridge tile and the top or edge of the ridge cap. The term ridge tile is not to be regarded as restricting the invention. Rather, it also includes all other elements covering the ridge or ridge, such as e.g. Ridge stones, ridge pans etc. The flow or ventilation space is closed off to the side by the first outer section bent upwards and correspondingly running upwards, which only releases segment-shaped overflow areas. In this way, the ventilation space is open on both sides of the roof to ensure unhindered outflow of the under-roof air to the outside, on the other hand, this space is protected against unwanted entry of all kinds of animals, rain and snow, etc., as far as possible. Due to the continuous formation of the flow or ventilation space from windward to lee, there is no forced flow, as is the case with individual channels. For example, wind entering the flow area at an angle is not deflected as in channels, but rather is swirled, so that the necessary negative pressure for roof ventilation is generated. Accordingly, the air flow can develop and move freely.

A good and quick heat dissipation is ensured both on hot summer days due to the strong air flow and on cold and rainy days for an improved and safe removal of moisture in the ventilation gap below the ridge tiles. Through the formation of the first and third outer section for the spatial and forceful closure to the ridge tile. A kind of hinge effect occurs between the second inner and the third outer section, so that the third outer section can optimally adapt to the inner surface of a ridge and / or ridge tile. It is therefore not necessary to bend on site, especially due to the use of a permanently elastic deformable material in order to adapt the ridge or cover cap according to the invention to the given ridge and / or ridge tile. The second outer section sealingly bridges the gap between the roof covering panels and the adjacent cover elements. Since the second outer section is arranged as a sealing element on both sides of the covering cap, the sub-roof area is thus completely sealed from roof side to roof side. Depending on the width of the second inner section and of the first and second outer sections, the covering cap can be completely covered by the ridge tile or partially protrude below it. In the former, the cap is not directly exposed to rain and snow. If the cover cap protrudes partially under the ridge tile, the longer design of the sections ensures an improved hinge effect.

In a preferred embodiment it is provided that the first and the third outer section are designed in the form of a plurality of elastic lamellae which merge into one another in a material-locking manner. Such a lamellar design is characterized in that the cover cap can be easily adjusted over the entire area of the ridge stone and has excellent stability. The lamellar design of the third and also the first outer section makes for an excellent Adaptation to the stair-like or conical contours of the ridge tile or ridge stone that often occur in the ridge direction. The slats can either just touch the ridge tile independently of one another or they can rest completely on the inner profile with their outer or contact surface. The ridge tile is only to be placed on the assembled ridge cap to ensure an elastic and permanent connection between the ridge cap and tile. Due to the design according to the invention, this not only results in a support in the middle of the ridge so that the roofer can walk on it safely, but the slats also ensure reliable external support for the whole.

The flow cross-section required to comply with DIN 4108 is preferably provided in that the spaces formed by a constant distance between the fins serve as overflow areas.

In a further development it is provided that the lamellae, which are preferably formed in one piece with the second inner section of the covering cap, are provided on the longitudinal edges of the first outer section with side lugs which are formed in one piece with the lamellae. These side flaps are preferably bent downwards and outwards relative to the lamellae of the first outer section, forming an obtuse angle, the angle being such that the cross section of the overflow regions tapers outwards and downwards starting from the first outer section. This nozzle-shaped configuration of the segment-shaped overflow areas between the individual fins results in the advantageous small losses of a nozzle flow for the air flowing out of the ventilation space. while in the opposite direction the high flow losses of a "Borda" mouth take effect. With free thermal convection without cross winds, the air flowing out of the roof into the flow space can flow out on both sides through the segment-shaped overflow areas in the first and optionally in the third outer section. In the case of forced convection, the air flowing in from the outside in the case of cross winds is prevented from flowing in by the one-sided contour of the overflow areas in the first outer section, in particular by contraction and swirling on the curved edges of the side flaps, while when flowing out of the overflow areas located on the opposite sloping roof due to the there existing rounding of the side flaps there is a significantly lower resistance. This leads to a slight negative pressure in the space between the ridge tile and cap, which has an advantageous effect on the flow from the interior of the roof through openings provided in the second inner section. The possibly moist air is extracted not only on the lee side but also on the windward side from the interior of the roof. An inflow into the interior of the roof is prevented by the negative pressure present. Furthermore, rain or condensation water can flow freely through the overflow areas in the outer sections. Water penetration is prevented by the curved edges of the side flaps and the angled third outer section.

In order to intensify the effects of the nozzle-shaped overflow areas, the side flaps preferably taper outwards starting from the respective lamella.

In a further preferred embodiment it is provided that the lamellae of the third outer section taper outwards at their free end. This increases the elasticity of the outer slats so that they can easily adapt to any inner profile and ensure an elastic and permanent connection between the ridge tile and the ridge cap. In order to intensify this effect, the individual lamellae of the third outer section can optionally be made somewhat narrower than the lamellae of the second outer section. In such a ridge cap, the ridge tile is only to be placed on the assembled cover, a pressing task by the ridge brick as in known plastic covers is no longer necessary, since the cover cap has already been deformed before assembly.

In order to provide a holder for receiving the second outer section in the area of the bend, the transition area between the second inner and first outer section is preferably divided into tabs by transverse slots. Two adjacent tabs can have the same, but also a different width, with the wider tabs, if preferred for flow reasons, possibly passing into the lamellae of the outer sections to increase stability. To form the brackets for the second outer section, the tabs merging into the slats of the outer sections in the form of a mirrored S and the tabs adjacent to them bent in an S shape in such a way that they form a clamping strip for receiving and fastening the second outer section serving as a sealing element. External sections of different designs can then be inserted into these terminal strips, the clamping action of tabs bent outwards and downwards ensuring reliable attachment of the sections. No additional brackets have to be attached or molded onto the cover cap, which also simplifies the manufacture of such a cap.

It is only important for the second outer sections, which can also have a different width, for example, that they bridge the gap between the roof covering plates and the adjacent cover elements in a sealing manner.

In the transition region between the tabs forming the clamping strip and the lamellae of the first outer section, longitudinal beads running perpendicular to the direction of extension of the lamellae are provided. The resulting stiffening in the area between the second inner and the first outer section prevents the terminal strips or brackets and the sealing element inserted therein from being pressed outwards. The elastic formation between inner and outer sections results accordingly between the third outer section and the second inner section.

The openings that remain even after the second outer section has been inserted and because of the bends in the transition area above the inserted sealing element can serve as seepage openings through which rain or condensation water can flow outwards so that it does not penetrate into the roof.

Metal strips made of aluminum, copper or lead can preferably serve as the second outer sections. The use of these materials offers the possibility of almost complete recycling without the associated loads known for plastics. In addition, the second outer section is extremely resistant, so that hardly any material decomposition occurs. If the cover cap protrudes with its second outer sections under the ridge tile, it is not attacked by UV radiation either, so that its service life is increased. Such an embodiment is particularly preferred when a smooth finishing brick is used, which is provided with a shoulder in the brick itself. One end of the metal strip is inserted into the terminal block, while the other, particularly smooth end of the second outer section, for example with a width of 15 cm, fits snugly on the heel of the roof tile and the ridge cap is accordingly easily attachable. Instead of a metal strip, rubber strips, e.g. from ethylene-propylene-diene terpolymers (EPDM) can be used. The use of copper has the advantage that this element is subject to natural oxidation. The copper oxide, which has been washed away from the rain by the metal, prevents the roofing slabs from being mossed and gives the impression of a roof covering that is always as new over a long period of time.

In a preferred embodiment, two metal strips, preferably made of different metal, are placed on top of one another. In one embodiment, one metal strip can be aluminum and the other one can be tin-plated lead.

The aluminum and the tin plating of the lead ensure that no lead carbonate gets into the waste water. Furthermore, when using aluminum and tinned lead, it is ideally adapted to any brick shape.

In another embodiment, a metal strip is again made of aluminum, but the other is colored lead. This firstly provides additional corrosion protection, secondly, if a red or brown coating is used, the surface corresponding to the brick color can be used.

Furthermore, the lower metal strip is embedded at the end facing away from the terminal strip by folding the upper metal strip back into it. This ensures an optimal termination of the second outer section at the end facing the bricks. It is prevented, for example, that air can penetrate into the area between the two metal strips, which is particularly undesirable if the side strips are not completely covered by the ridge tile or the ridge stone, but rather protrude partially below it. Since the second outer sections are then also directly exposed to rain and snow, this also cannot penetrate between the metal strips.

In the above-mentioned embodiments, the metal strips can either be corrugated or can be designed without corrugation.

In order to be able to reliably fix the second section in the terminal strips, the metal strips either have a specially designed edge area or else an edge area is fixed in an additional metal back. For this purpose, the metal strips can have a cross-sectional constriction in this edge region, for example. In the area facing away from the metal back, the strip can be angled for better support on the roofing panels.

The metal back itself can be made of stainless steel, for example, or also of galvanized sheet metal. Such a metal back can also be used for other embodiments of the second outer section, for example when using a rubber strip, which would otherwise have to be provided with a specially designed edge area.

In another preferred embodiment of the invention it is provided that the second outer section of the cover cap consists of a brush-like element. The bristles of such a brush-like element can extend to the bottom of the troughs of the roofing tiles or roof tiles, but can also be spread or pushed away in the area of the highest elevations of the roofing tiles. A brush-like element of this type can thus seal against a wide variety of contours. The element also has the roof covering panels or

Roof tiles require the necessary flexibility and softness, so that it clings tightly to the contours of the roofing tiles or roof tiles even with the slightest force.

The brush-like element particularly advantageously has bristles made of aluminum wires or copper wires. Since these bristles, which can also protrude under the ridge tile, are exposed to the weather and thus also to UV rays, the inventive design creates a particularly weather-resistant and resistant second outer section of the covering cap. Instead of aluminum wires, the brush-like element can also use natural fibers as bristles, e.g. Horse bristles. Through the use of such natural fibers, a cover cap is created which later also has no contaminated sites which would have to be disposed of in a complicated manner.

If the brush-like element is stepped towards the roof covering panels, then it fits particularly well to the contour of the panels. On steep roofs, the bristle contact pressure values can be reduced and the individual bristles lie evenly and flat on the roof covering plate contour. Instead of brush-like elements, sealing bodies made of filter foam, which are preferably wedge-shaped, can also be used as the second outer section. Or a dimensionally stable fabric tape is used. When using these sealing bodies, no consideration has to be taken when applying the covering cap to the ridge slat with regard to the profiling of the roof covering plates. The second outer section can also be a plastic part adapted to the profile of the roofing panels. It is also possible that the section is comb-like is. Such a comb-like section easily adapts to any external profile due to its flexible teeth. Furthermore, the second outer section can be a soft, stretchable polyisobutylene film strip, in which an expanded metal mesh is embedded, which in particular has an extensibility of 50 to 150% in the longitudinal direction and an extensibility of 20% in the transverse direction and a resilience of <0.5% having. When using a cover cap with such an outer section, any profiling of the roof covering panels is possible, since the section has a high degree of extensibility in the longitudinal direction. The low extensibility in the transverse direction ensures that the covering cap attached under the ridge tile also provides a visually appealing image if the outer section protrudes under the ridge tile, since this then has a clean longitudinal edge. The second outer section can be optimally fixed to the roofing panels using adhesive and, if necessary, glued to it.

Today, more attention is paid to the economic recycling of old and waste materials through their return to the material cycle. In the case of conventionally used materials such as hard plastics, however, recycling is extremely difficult, especially if these are formed in combination with other materials. If recycling is not possible, all that remains is landfilling or incineration with the associated subsequent loads as alternative disposal options. However, this is not desirable for environmental reasons. Another disadvantage of using plastics is that they are not resistant enough to the increasing UV radiation, so that even plastics such as polyvinyl chloride (PVC) are attacked.

Therefore, further developments provide that the permanently elastic deformable material is metal and that the first and the third outer section are also made of metal. The metal can be aluminum, copper or galvanized sheet metal. The use of aluminum, copper or galvanized sheet metal for the cover cap enables almost complete recycling. The cover no longer entails consequential loads that occur when using plastics. In addition, the cover cap according to the invention is extremely resistant, so that hardly any rotting occurs. The masking tape is also not attacked by UV radiation, in particular by increasing UV radiation, so that the service life is increased compared to conventional masking tapes. The durability can be in the range of the 30-year guarantee that brick manufacturers give on their bricks. Furthermore, when using aluminum or copper sheets, an ideal adaptation to any brick shape is guaranteed. The aluminum or the galvanized sheet metal is mostly monochrome, but is also preferably coated in two colors. This firstly provides additional corrosion protection, secondly, if a red or brown coating is used, the surface corresponding to the brick color can be used.

The metal used for the inner and the first and third outer sections preferably has a thickness of at least 0.2 mm, but at most 1.5 mm. Cover caps with a higher sheet thickness are no longer deformable. If the sheet thickness is lower, the metal cap is no longer sufficiently stable.

In order to allow the "moist" air to flow out of the under-roof area into the ventilation space and from there to the outside, the openings serving as overflow openings are arranged in the second inner section and are flared at their edges. These overflow openings are provided in the falling part of the cover cap due to the bending of the second inner section. The flares protect the overflow openings from the ingress of water running off the cover, and an optimal flow of the air is ensured. The overflow openings are preferably aligned with the lamellae, so that they are optimally shielded from incoming air from the outside.

The overflow openings can be, for example, oval, rectangular or rectangular openings with slightly rounded corners arranged parallel or perpendicularly in the lamellae, but these rectangular or oval openings can also be arranged offset in two rows on the second inner section . Furthermore, they can be individual round openings which are arranged in alignment with the lamellae, but also two round openings arranged one below the other. The choice of the appropriate openings depends on the desired air flow to be achieved. The punching out of all these overflow openings and also the overflow areas in the ridge or cover cap according to the invention provides for additional ventilation openings, openings or areas in a space-saving manner compared to the prior art. The stability of the manufactured However, this does not reduce the covering cap in any way compared to the known covering caps.

By means of transverse grooves provided according to the invention in the first middle section, the covering cap is reinforced in the upper region above the ridge batten in order to prevent a gutter-like bulging with the risk of water.

Such a cover cap can easily be preformed due to the punched-out and bending before mounting on a ridge slat. If the ridge cap is pre-angled a little more, a good pre-tension results after nailing or screwing onto the ridge batten, which is disadvantageously generated by the ridge stone or the ridge tile in a plastic cover. Accordingly, in the ridge cap according to the invention, it can be checked before the ridge tile is fastened whether there is a defined optimal placement or support of the ridge tile. Furthermore, the ridge cap can also be adapted to steeper roofs by preforming it accordingly. The fact that the sealing elements can be inserted into the brackets formed as strong fastening terminal strips at the lower edge of the cover cap means that the cover can be easily stacked. However, the possibility of stacking is also conditionally provided with sealing elements seated in the terminal strips.

Because nail holes are punched into the permanently elastic deformable material, the cover cap can be reliably attached to a ridge slat. Alternatively, the cover cap can be screwed onto the ridge batten.

The ridge caps, which have been cut to a predetermined length after manufacture, are preferably asymmetrical and are placed on one another during assembly such that two transverse grooves each lie on one another or engage in one another. As a result, the grid of the middle part remains constant over the entire ridge. Furthermore, the middle section of the ridge cap can be provided with a middle marking in order to place the cap exactly on the ridge batten or ridge batten.

According to the invention, the features mentioned above and those listed further can be used individually or in any combination with one another. The mentioned embodiments are not to be understood as enumerations limiting the invention, but rather have an exemplary character.

Further advantages and features of the invention result from the claims and from the following description, in which an embodiment of the ridge and / or ridge cover according to the invention is explained in detail with reference to the drawings. It shows:

Figure 1

The ridge or cover cap 1 of a ridge and / or ridge cover shown in FIG. 1 has a first central section 2, to which a second inner section 3 is connected on each side. As can be seen in FIG. 2, the mutually adjacent sections 2 and 3 are angled toward one another to form an obtuse angle. This bending takes place via folding means 5, which are arranged in the transition area between the first middle section 2 and the second inner section 3. As can be seen from FIGS. 3 and 4, the covering cap 1 according to the invention is fastened to a ridge slat 4 via the first central section 2, in particular nailed or screwed thereon.

1, the second inner section 3 is provided in its longitudinal direction with overflow openings 6 which have flanges 7 at their edges. The liquids flowing away from the cap 1 are guided around these flanges 7 in order not to get into the roof interior 8. In the illustrated embodiment, the openings 6 are round. But they can also be oval, rectangular or rectangular with more or less rounded corners, these openings can be aligned parallel or perpendicular to the folding means 5. Furthermore, a plurality of rows of overflow openings with openings which are optionally offset from one another can be provided on the second inner section 3. About the in this embodiment evenly in the longitudinal direction over the the entire cover cap 1 distributed overflow openings 6, the air (see FIGS. 3 and 4) can flow out of the under-roof area 8 and get into the ventilation space 9 between the cover cap 1 and a ridge tile 10 or ridge tile or a ridge tile arranged above it.

The second inner section 3 is followed by a first outer section 11 (see FIGS. 2-4). Brackets 13 are formed in the transition area 12 between the second inner section 3 and the first outer section 11. These holders 13, which are only indicated in FIGS. 2-4, are obtained in that the transition region 12 between the second inner section 3 and the first outer section 11 is divided into tabs, also not shown, by transverse slots, not shown. Adjacent tabs can have a different width to each other. In the case of different widths, the narrower tabs are S-shaped and the wider tabs in the form of a mirrored S are bent towards one another in such a way that they then form the clamping strip 13 serving as a holder for receiving and securing a second outer section 14, which serves as a sealing element . The sealing element 14 adapts optimally to the profile of the adjacent roofing panels 15 which rest on roof battens 16 of the roof structure.

At the end of the tabs 13 of the terminal strip 13 bent downward in the form of a mirrored S, the first outer section 11 is bent upward. In this area longitudinal beads are provided for stiffening perpendicular to the direction of extension of the tabs. A third outer section 17 then adjoins the first outer section 11. This is compared to section 11 angled outwards by bending. Both the first outer section 11 and the third outer section 17 are designed in the form of a plurality of elastic slats 18, 19 which merge into one another in a material-locking manner. These slats 18, 19 pass over the tabs of the transition region 12 into the second inner section 3 of the cap 1. The entire inner sections 2, 3 and the outer sections 11 and 17 are integrally formed with one another. Only the second outer section 14 is made separately and is inserted into the strong clamping strips 13.

If the tabs of the transition region 12 are provided with different widths, the wide tabs in the form of a shoulder in the area of the longitudinal beads merge into the then somewhat narrower slats 18 of the first outer section, which on its longitudinal edges have side tabs formed integrally with the slats 18 20, 21 is provided. The side plates 20, 21 are bent downwards and outwards relative to the slats 18. The spaces 22 of the cover cap 1 formed between the lamellae 18 and the side flaps 19, 20 serve as overflow areas through which the air can flow out of the ventilation space 9 or can flow into it. As can be seen in FIG. 1, the overflow openings 6 are aligned with the lamellae 18, 19 so that they are shielded from incoming air.

The side flaps 20, 21 of the slats 18 of the first outer section 11 are bent downwards and outwards in such a way that the overflow regions 22 taper downwards and outwards starting from the first outer section 11. Likewise, the side tabs 20, 21 taper outwards from the respective lamella 18.

The resulting nozzle-shaped contour of the overflow areas has the advantageous low losses of a nozzle flow for the air flowing out of the ventilation space 9, while the air flowing in from the outside is subject to the high flow losses of such a "borda-like mouth". With free convection, the air flowing out of the roof interior or the lower roof space 8 can flow out on both sides through the overflow openings 6 into the ventilation space 9 and from there via the overflow areas 22 to the outside. In the case of forced convection, the air flowing in from the outside is prevented from flowing in by the contour of the overflow regions 22, while the air flowing out of the ventilation space 9 can flow out on the opposite sloping roof through the overflow openings 22 located there due to the substantially lower resistance.

The lamellae 19 of the third outer section 17 are formed somewhat narrower in the illustrated embodiment than the lamellae 18 of the first outer section 11. At their free end 23, these lamellae 19 taper outwards. This free end adapts optimally to any inner contour of the ridge tile or ridge stone 10 etc. Due to the bending and shaping of the first outer section 11 and the third outer section 17, there is thus a flexible design of the covering cap between the second inner section 3 and the third outer section 17, which reinforces the optimal adaptation to the inner contour of the ridge tile 10.

However, the first and third outer sections 11, 17 are not only used for ventilation of the ventilation space 9 and of the roof interior 8, but also ensure it on the one hand, a sufficient space between the ridge tile 10 and the covering cap 1 and, on the other hand, serve as a closure for the continuous flow or ventilation space 9 between the top of the covering cap 1 and the underside of the ridge tile 10.

The ridge tile or ridge tile 10 is fastened to the ridge slat 4 by means of clamps 24 and is spaced apart from the cover cap 1 to form the continuous flow space 9. In the exemplary embodiment shown in FIGS. 3 and 4, its edges 25 protrude beyond the sealing elements 14 of the covering cap 1. In this way, the defined space or ventilation space 9 between the covering cap 1 and the ridge tile 10, which is necessary for optimal ventilation , in particular the underside of the ridge tile 10, is formed. Accordingly, air flowing into the intermediate space 9 can entrain air flowing out of the roof interior 8 and discharge it to the surroundings.

In the middle section 2 of the ridge cap 1, nail or screw holes 26 are punched. These holes 26 are preferably arranged between the overflow openings 6. In each case offset to the overflow openings 6, transverse grooves 27 are embossed from below in the central section. These transverse grooves 27 serve to reinforce the ridge or cover cap 1 on the upper part above the ridge batten 4 and prevent a channel-like bulging with the risk of water.

In order to be able to connect the individual cover caps 1 to each other in the ridge area, grooves or slots can be provided at one end of the cover cap, and then at the other end of the cover cap a spring is provided which engages in the groove or slot. This tongue can be wedge-shaped, for example, in order to ensure a reliable hold in the groove or the slot of the other cover cap. As an alternative to this, the inner sections of the asymmetrically designed covering cap can be followed by an overlap section which is bevelled on its outer sides and which can be placed on the subsequent covering cap in such a way that two transverse grooves lie on top of one another and engage in one another. As a result, the grid remains constant over the entire ridge.

The ridge and / or ridge cover is produced by first providing a permanently elastic deformable material, for example an aluminum or copper sheet or galvanized sheet with a thickness of 0.5 mm, with folding means in the longitudinal direction. Overflow openings with flares are then obtained in the inner sections defined in this way by punching in the longitudinal direction. A first and a second outer section are punched out in a lamellar shape, with side tabs remaining on the longitudinal edges of the slats of the first outer section. The transition area between the second inner and the first outer section is provided with transverse slots by punching or cutting in order to form tabs in this transition area. At their end facing away from the middle section, the tabs are provided with longitudinal beads running perpendicular to their direction of extension, for example by embossing. Furthermore, the central inner section is provided with transverse grooves by embossing from below. Openings for attaching the cover cap to the ridge are punched between the transverse grooves.

Next, the individual sections of the metal sheet are angled against one another by folding or bending. This is done by angling the second inner section downwards relative to the first middle section, angling the tabs in the transition region between the second inner section and the first outer section once in an S-shape or in the form of a mirror-inverted S, thereby creating a Clamping strip for receiving the second outer section is created, the first outer section at the end of the transition region is bent upwards and the third outer section is bent outwards relative to the first outer section. Likewise, the side flaps are bent downwards and outwards relative to the lamellae of the first outer section in such a way that overflow regions tapering downwards and outwards in their cross section result.

The sealing elements can be slightly pre-angled (maximum 30 °) in the terminal strips of the cover cap, which may be cut to a predetermined length, so that excessive stresses do not occur on the terminal strips when applied to the ridge batten.

A cover cap produced in this way and preformed downwards already has a good pre-tension during assembly of the ridge cover, which is only produced in the plastic cover by the ridge stone or by the ridge tile or the ridge pan. In the cover cap according to the invention, the position of the cover and the sealing elements with respect to the roof covering plates and accordingly the sealing function of the ridge cover can be checked already after fastening before the ridge stone is put on.

A pressing with a corresponding deformation of the cover cap as in the prior art no longer takes place by placing the ridge tile or ridge stone.

Due to the design according to the invention with elastic slats as the first and third outer sections, the conical inner contour of the ridge tile can be optimally compensated. The slats can rest completely with their outer or contact surface on the inside of the ridge tile (see Fig. 4). However, it is also sufficient for the stability if they just touch the inside of the ridge tile (Fig. 3).
