If, however, the pre-product is built from layers under different areas of the fabric of different fiber materials, e.g. B. two different, depending on the pattern to choose, but fiber fleeces of opposite color used, which there is also as further possible variations placed on top of each other and then together in the advance, the needles are needled differently deep in the surface direction according to the invention, so 20 structures to penetrate. There are basically two ways to get another pattern. One possibility, namely the possibility of a colored one, is to have several hixitereinan designs of the finished product in the needle holder. By inserting rows of needles that close and pierce the needles, they are designed to be of different lengths on the back or on the side of the finished fabric to a partial but different stroke movement relative to the emergence of the fiber materials of the other colored to the fabric carry out. By controlling the layers behind it. Depending on the tightness of the locking elements in the needles of different types of needling according to the work program, there is thus the possibility that one of the control devices now results in a more needling or needling either from a long, deeply piercing less large color change of this back of the goods. 30 the needle or a short, shallower-the more tightly the needles penetrated into an area is effected by urgent needle
the more intense the original color. The other possibility is to change a needle through the different colored fibers of the several superimposed blocking elements of the layers. Conversely, if you want to assign areas that retain the original color in their effective barrier layers, then you only need to prevent the needles from moving freely or completely at these points, only to a greater or lesser extent, only to a small extent or at all not from the needles. B. to pierce a first locking element in its effective. Brought into position, the needle is

Whether in the production of a textile surface or the lifting movement of the device one immediately finds a support, more of a relief-like structure or more, and has no mobility whatsoever. If a colored design is sought, however, this first blocking element in its free color, layer thickness, impermeability and fiber material fork layer and another blocking of the needled surface structure to be formed in a wide element only in its blocking layer, is predetermined at the limits. If you use z. For example, when the machine is in motion, first a Vereiner pre-product has a relatively large upper slidability around a short distance of the needle, from which the needles can be inserted into the product until it sticks to this second locking element arrives and finds its support there, with which a pronounced relief-like structure rest of the working movement the needle slightly the door, especially when one pierces the density of the needling in the surface structure. As can be seen, individual areas of the pattern can be selected very differently by arranging several locking devices accordingly. Conversely, with thin fiber layers and elements with unchanged size of the lifting movement, slight differences in the density of the needling between the flat structure and the needle holder can still be expected on the upper side of the goods due to a control device via their work program structure, but with strong differences Various penetration depths of the needles lent fiber colors on the underside of the finished 55 optionally determine.

For borrowed. The definition and modification of the work It is advantageous to warm up, while hot air is very easy and quick to get into the program to be blown in, as one feed in this way.

A simple way of designing the device consists in providing longitudinal guides for the needles in the needle holder and making them so long train that they have a clamping area for the needles locking in the working position and above additionally comprise a displacement area, the length of which is at least equal to the penetration depth of the needles is. As a locking element, it is best to use one that is movable transversely to the longitudinal guide with the control device connected bolt. To determine the exit depth of the needles from their storage, .sind Stops are provided between the needle and its longitudinal guide. In the simplest case, the Needle at its upper end a contact collar with which it is in a locking position on a corresponding Paragraph rests in the longitudinal guide. The paragraph is at such a depth of the longitudinal guide that the working end of the needle protrudes in the blocking position of the blocking element in the desired length.

It is advisable to keep the bolt in the locked position with a spring and at the end of the actuation of the bolt to connect a tension member connected to the control device, e.g. B. the Harness cord of a jacquard machine. This tension member displaces the locking end according to the control program of the bolt in its ineffective position, opposite to the acting spring force. In the In this case, the machine's working movement is accommodated in the needle holder and resiliently therefore ineffective for piercing.

To the connection between the locking element on the one hand and the control device on the other hand as possible To make it easy and less prone to failure, it is advisable to use the transport device together with the Flat structure opposite the needle holder fixedly attached in the needle machine and the control device to make movable up and down in the longitudinal direction of the needles.

Provided a needle is ineffective position of the locking element has been in a freewheeling position, it is important to ensure that before the next one Working cycle, the needle can return to its effective position, so with a corresponding Control command move the locking element into its effective position and the needle to pierce can be supported in the fabric. Since you cannot rely on that recommends that the needles return to their original position quickly enough by themselves by gravity it is necessary to provide return means which quickly and reliably ensure a return movement of the needles. In the simplest way, it is recommended to reset the needles that are in freewheel on the Needle holder in the upper part of the displacement range of the needle guide in this longitudinally displaceable mandrel to be arranged, which can be moved up and down in particular in the work cycle of the needle machine. they seem on the top of the freewheeling needles. The up and down movement in the work cycle the stroke movement between the flat structure and the needle holder can be easiest in this way realize that the transport device with the carrier for the reset domes to a common movable working unit is connected.

The device according to FIG. 1 consists of the actual working machine which effects the needling 10 and bucket control device 11 arranged above it.

In the present case, the work machine 10 has only a single needle holder 12, which here carries only a single row of needles 13, of which the side sectional view of FIG. 1 only the foremost needle can be seen. The needles are evenly spaced in the row next to each other. The needle holder may also have a plurality \ such needles or else the device have a plurality of such holders of needles, but what is the erfindungsigemäßen device of minor importance for the understanding of the structure and mode of action.

The needle holder 12 is fixed in place in the device. The needle holder 12 has to accommodate of each needle 13 has a stepped bore 14, the lower narrow part 16 corresponding to the desired Storage depth of the needle 13 is formed and has a width that the bearing portion in a sliding fit the needle grips. At the upper end, the needle has a head 17, which is at the stage of the bore 14 comes to the plant.

The upper part of the bore is designed and wider according to the head cross-section of the needle serves as a displacement area 15 of the needle. Its length is at least equal to the desired penetration depth 18 of the needle, which is visible with its working end protruding from the holder 12. This working end 19 has lateral notches in the needle shaft, the barbs for grasping the Form fibers of a textile fabric 20, which is below the needles by a multi-part transport device 21 is pushed past step by step.

In the present case, the sheet-like structure 20 consists of a fiber fleece that is transported by the transport device is moved further in the direction of arrow 22 intermittently. The transport device has for this purpose 21 both in front of and behind the needle holder 12 a feed mechanism, each of which consists of a pair of transport rollers 23, 24, the untreated fiber fleece in front of the work place of the device 20 and behind the job, grasp the needled nonwoven fabric between you and rotate it in the Move on according to the arrows drawn. In the area of the work place has the transport facility below the textile fabric, a table top 26, which is at the work site of the device has a transverse slot 27 for the working ends 19 of the needles 13 to pass through. Above the sheet to be banded 20 is a hold-down plate 28, which is a corresponding transverse slot 29 to carry out the

13 needles. The hold-down plate 28 serves to remove the textile fabric when the needles are pulled out Withhold 20. The entire transport device 21, consisting of the transport rollers 23,24, the table top 26 and the hold-down plate 28 is in the sense of the double arrow shown 30 moves up and down in the longitudinal direction of the needle.

The needle holder 12 has a length corresponding to the clamping area 16 for the needle Distance a transversely to the bore 14 movable bolt 31, which is from a stationary frame 32 is added longitudinally displaceable. The latch usually engages with its front one Locking end 33 above the needle head 17 in the bore 14 and thus closes the above located displacement area 15. This locking position of the bolt 31 is shown in FIG. This barrier is ensured by a compression spring 34, one end of which on the movable bolt 31 and the other end of which is supported on the stationary frame 32.

In this blocking position of the bolt 31, the needle head 17 receives a support, so that during the upward movement of the fiber fleece 20 by means of the transport device 21, the longitudinal displaceability of the needle is prevented and when it hits the fiber fleece 20 is pierced through this. In the subsequent downward movement of the transport device 21, the needle head 17 is supported on the step inside the bore 14, so that the fiber fleece 20 at the work site by means of the downwardly moving Hold-down plate 28 is stripped from the working end 19 of the needles 13.

In order to obtain any pattern of the textile fabric during needling, the suggests Invention furthermore, the shown supporting position of the needle 13 by the located in the locked position To eliminate latch 31 and to bring the needle 13 into a free-running position in which it is free in the displacement range 15 is slidable.

For this purpose, the locking end 33 of the bolt 31 must counteract the action of the compression spring 34 in a release position are brought, in which the needle head 17 is open towards the displacement area 15. to For this purpose, the bolt 31 is withdrawn via a cord 36 serving as a pulling element, which is attached to the engages free operating ends 35 of the bolt. The movement of the cord 36 to pull or release of the bolt 31 is determined by the control device 11 shown.

This control device 11 is designed in the present case in the manner of a jacquard machine. That The entire work program for controlling the needles 13 is stored in the present case in a card 40, which contains the entire sample report recorded. Do not serve as recording media Holes shown in the card or "missing holes", each one opposite to one another Forward the control command to the bolt 31, as is to be shown. The holes are for each duty cycle of the device combined into groups that contain the control commands for all needles of the device recorded included and each shared by the reading mechanism arranged above the card 40 41 are scanned mechanically. After scanning such a group, the card 40 is advanced through a card cylinder 42 until the next group of recorded Control commands has been introduced to the reading mechanism for scanning.

The entire control device 11 is in comparison with the device 10 described for reasons for clarity on a larger scale in FIG. 1 shown. As a reading mechanism 41 has the device a number of thin feeler needles 43, which are held by suitable holders vertically are held above the reading point of the card cylinder 42. Of the feeler needles 43, only this is The front row can be recognized because there are eight needles next to each other for reading off with the same tightness In the card 40 arranged scanning points are used. Behind the feeler needles shown are in numerous rows further appropriately designed feeler needles with associated still to be named further components, corresponding to the number of differently working needles 13 of the needling device 10. Each of the feeler needles 43 is hinged to an auxiliary plate 44, one end of which is on the front pressure grate 45 rests and its opposite end passed through a perforated plate 46 is. The mode of operation and the structure of the control device 11 should now be based on the for the illustrated needle 13 serving control parts are explained in more detail.

The mode of operation of the needle 13 is determined by the feeler needle 43 ′ of the reading mechanism 41. To scan the card 40, the printing grate 45 moves obliquely to the bottom left in Fig. 1, whereby the auxiliary sinkers 44 together with the auxiliary sinker 44 'to be considered here lower until the feeler needles 43 sit down on the map. The feeler needle 43 'to be considered finds a hole in the card 40 before, it falls through the card. The auxiliary board 44 ′ rests on the pressure grate 45 and cannot be detected by this when it moves in the longitudinal direction of the auxiliary sinkers 44. The auxiliary board 44 'consequently remains at rest and is not capable of the associated one arranged behind it To push back the control needle 47 ', so that the plate 48' remains in the relaxed position shown, in the its hook-shaped end 54 'engages over a knife 49' of a knife basket that is movable up and down. the The consequence of this is that the knife 49 'grasps the plate 48' and in the direction of the double arrow shown 50 moved up. The cord 36 attached to the circuit board 48 is passed through the perforated board 51 with pulled up. The cord 36 is, as in FIG. 1 can be seen through an eye 37 in the frame 32 of the device 10 passed through and attached to the actuating end 35 of the bolt 31. The aforementioned tightening of the cord 36 is consequently the latch of the effect of the Compression spring 34 moves counter to its release position. With the now beginning stroke movement of the Transport device 21 in the direction of double arrow 30 pushes needle 13 with the tip of its Working end 19 on the nonwoven fabric and, in the absence of an abutment, is 17 above its head freely pushed up into the displacement area 15 without the working end penetrating the fiber fleece can. It should therefore be noted that a hole in the card 40 means that the needle 13 is in the associated Duty cycle does not penetrate into the nonwoven fabric 20.

After the transport device 21 has reached the uppermost point of its stroke, the downward

movement, it is desirable that the needle 13 as possible simultaneously without a major time delay also slides down in the guide until finally the needle head 17 rests on the Stage of the bore 14. Since the low weight of the needles for an exact return of the needles in If their initial position is not sufficient, resetting mandrels protrude into the bores 14 of the needle holder 12 from above 38 a, which with its rear end on a in the sense of the drawn double arrow 52 are clamped up and down movable carrier 39. A is used to fasten the reset domes 38 Grub screw 53. The movement of the carrier 39 with the resetting mandrel 38 takes place in the same working rhythm like the lifting movement 30 of the transport device 21. This has the consequence that after reaching the lower reversal point of the lifting movement of the transport device 21 of the reset mandrel 38 has also returned the needle 13 to its starting position shown. Now the feed mechanism will 23, 24 moved further so that the needles 13 are in front of the next following piece of the fiber fleece 20 get that now in the next working cycle according to the records in the control program 40 is optionally treated with the needles.

It is now assumed that the needle 13 shown will be inserted in the next working cycle target. To do this, the card 40 must be moved one step further. To do this, the pressure grate moves 45 diagonally upwards and thereby lifts all auxiliary sinkers 44, whereby the earlier in the Card 40 through a hole collapsed feeler pin 43 is pulled out of the card. Now the switch Card cylinder 42 to one recording position further.

It is assumed that there is now no hole in the feeler needle 43 '. The feeler needle 43 'therefore remains in its raised position, just as the auxiliary plate 44' also remains in this position. In the Above-mentioned movement of the pressure grate, the auxiliary plate 44 'is of the bent parts captured and pushed back. The auxiliary plate 44 'presses with its head at the opposite end against the control needle 47 ', with which the associated plate 48' with its hook 54 'having Leg is pushed back relative to the knife 49 '. Now leads the knife basket together with the If 49 'cut out the lifting movement in the sense of double arrow 50, then the blank 48' is not detected. It remains in its position shown and does not exert any tension on the cord 36 connected to it from, whereby the bolt 31 in its in F i g. 1 remains blocked.

The cords shown connected to the remaining plates 48 grip in a corresponding manner at the end of the actuation of further, not shown in more detail bolt, which the needles 13 optionally between Bring the support position and release position according to the desired pattern to be formed. It could if the width of the pattern repeat, which only covers part of the needles, is applied to the bars Identical needles are the ends of cords connected together to a single one Attack board 48 and are operated jointly by this.

2 and 3, a needle-punched nonwoven fabric 60 is shown in plan view and in sectional view, which is shown in FIG the device according to FIG. 1 has been treated.

This consists of two superimposed nonwovens 61, 62 of opposite colors, z. B. be that The non-woven fabric 62 is colored yellow and the non-woven fabric 61 is colored blue. Before laying the fleece on top of each other, between This sprinkled a powder 63 made of thermoplastic material, which after completion of the product by heating an additional welding of the layers of the two on top of one another Fiber fleeces 61, 62 causes.

ίο The two nonwovens 61, 62 are now from the Transport device 21 of the work station of the device 10 according to FIG. 1 fed where the needles 13 according to the work program 40 of the control device 11 optionally in the to be treated To be stabbed well. Page 64 in FIG. 3 is the entry side of the needles into the Non-woven fabric; this side is turned upward in the device 10, while the opposite surface side 65 down against the work table 26

ao of the device 10 has. In the event of a puncture, fiber parts of the fleece 62, as in FIG. 3 is shown schematically, pressed into the substrate, ie into the lower fiber fleece 61 in the device. It i a recessed portion 66 is formed in this case in the nonwoven fabric 60 on the side 64 of the finished product. On the exactly opposite surface side 65, however, a color area arises which, if the needling is sufficiently dense, practically only shows the yellow fibers of the fleece 62 that are passed through at this point. These color areas are denoted by 67 on the rear side 65 of the nonwoven fabric 60.

It is now assumed that needling occurs at a low density in the neighboring points 68, the fiber fleeces 61, 62 practically retain their original thickness at these points, which means that this surface side 64 the raised areas 68 arise. On the back 65 of the finished product 60 appear color areas 69 with practically the original blue color of the fiber fleece 61, because at these points there was hardly any change in the distribution of the fibers. In Fig. 2 is the plan view is shown on a section of such a fiber fleece looking towards the colored surface side 65. The differently colored areas 67, 69 are labeled. It is easily possible through appropriate Punching the card 40 gradual transitions in color between the blue 69 and the Yellow 67 can be obtained if the penetration density of the needles is between these two extreme values changes. This has a corresponding effect on the opposite surface side 64 of the product 60 Transitions in the relief height between the extreme values 68, 66.

Depending on whether for a specific application a superficial structuring or a superficial colored design made is to be used, the type of needles to be used is modified, e.g. B. in terms of size and the number of needles, or the layering of the preliminary product is chosen differently. If you want the relief structure, In any case, this is how the top of the nonwoven fabric pierced by the needles comes first Application, while in the case of a colored usable area, the opposite back of the substance is used.

In Fig. Figure 4 is the use of the nonwoven fabric of Figure 4. 3 shown for a floor covering 70. Here is

the nonwoven fabric 60 with its colored surface side 65 as the visible side turned upwards and on a felt-like Carrier 71 of greater thickness is applied and once again a light, customary needling process subject, as indicated by the needle pricks 72 in FIG. The structured page is 64 here, as mentioned above, facing the carrier 71 and therefore invisible. The carrier 71 is in turn made up of several layers; he wears an additional fabric 73 on the underside the loosely uniform needling 72 does not become the colored image on the visible side 65 of the floor covering more noticeably changed.
