Fig. 2 is a cross-sectional view taken in the direction of the arrows joined to i o line 2-2 in Fig. 1;
Fig. 3 is a cross-sectional view taken in the direction of the arrows joined to line 3-3 in Fig. l; and Fig. 4 is a side cross-sectional view showing the laminate of the present invention in a roof vent construction.
15 Description of the Preferred Embodiments Fig. 1 is an overhead view of the matting layer 11 of the laminate of the present invention which comprises randomly convoluted polymeric filaments.
This matting layer can, for example, be made in accordance with the method described in U. S. Patent No. 4,252,590 to A. Rasen, using a profile 4 which is the a o negative image of the profile 5 with square truncated upper surface 6 as depicted in Fig. 3 of the Rasen et al patent.
The matting 11 has formed in its body a plurality of truncated pyramidal cusps 12 which have sloping sides 13, as best seen in Figs. 2 and 3, and a generally flat floor, or apex, 14 at the point of truncation. These cusps can be readily formed by extruding the plastic filaments, while they are still capable of deformation, onto the previously described negative image of the profile shown in Fig. 3 of the Rasen et al. patent. The matting layer 11 of the laminate of the present invention also has at least one outwardly extending edge marginal portion 15 which is coplanar with the upper surface 16 of the matting layer 17 thereby forming bases for the cusps 12 and a coplanar wing 15, or flange, portion for the matting layer 11 (as best seen in Fig. 2). Preferably, a pair of flanges 15 extend lengthwise of the layer 11.
The laminate also comprises a fabric backing 18 bonded to the opposed bottom of the truncated pyramidal cusps and, thus,. the matting layer itself. This fabric precludes the entry of insects, debris, and other unwanted elements when the laminate is used as a roof ridge vent construction. This fabric backing extends outwardly towards the "wing" portions 15 of the matting layer 11 and is bonded (preferably, heat bonded) to those outwardly extending, planar edge portions of the matting laye=- .
In a preferred embodiment, the matting layer 11 previously described is constructed from a series of nylon 6 macrofilaments which have a diameter of from about: 200 to about 1000 microns, preferably about 550 microns. These filaments form a planar mesh construction that takes the shape of the cusp structure, upon formation, as described above, wherein the cusps have a height of from about 0.25 inch to about 2 inches, preferably about 1 inch. The weight of the matting layer 11 can range about 30 to about 100 grams per square foot, preferably from about 50 to about 60 grams per square foot, with the preferred width of the laminate ranging from about 6 inches to about 15 inches, depending upon the roof shingle structure, but preferably will have a width of from about 10 to about 11 inches.
A suitable fabric 18 to use in the present laminate is available under the trademark COLBACK from Akzo Nobel Nonwovens Inc. and is preferably a bi-component yarn of polyester and nylon. A most preferred fabric has the following specifications: weight - about 100 grams per square meter; thickness - about 0.5 mm; tenacity - about 44 paunds per inch; elongation - about 34~; and apparent opening size (AOS) - about 40.
In a preferred embodiment, the matting layer has a hinge portion 19 which can be flexed to conform the product to the roof ridge of a roof as shown in Fig. 4.
The laminate described herein can be appropriately fastened to a roof deck and shingle portion 20 of the roof, over the ridge vent 21, using nails 22 (which will, of course, be hidden from view by the overlapping shingles 23 once they are installed) to allow for appropriate air flow (as shown by the arrows in Fig. 4) through the vent and through the matting layer 11 of the laminate so that the needed ventilation of the building's attic: or uppermost floor takes place. The cap shingles 23 are conventionally installed over the laminate with the "wing" portion of the laminate providing support.
The laminate of the present has a number of advantages over previous laminate constructions known to persons of ordinary skill in the art. The novel pyramidal structures of the matting layer, which make this product a "cuspated" rather than "non-cuspated"

15 Description of the Preferred Embodiments Fig. 1 is an overhead view of the matting layer 11 of the laminate of the present invention which comprises randomly convoluted polymeric filaments.
This matting layer can, for example, be made in accordance with the method described in U. S. Patent No. 4,252,590 to A. Rasen, using a profile 4 which is the a o negative image of the profile 5 with square truncated upper surface 6 as depicted in Fig. 3 of the Rasen et al patent.
The matting 11 has formed in its body a plurality of truncated pyramidal cusps 12 which have sloping sides 13, as best seen in Figs. 2 and 3, and a generally flat floor, or apex, 14 at the point of truncation.

Preferably, a pair of flanges 15 extend lengthwise of the layer 11.
The laminate also comprises a fabric backing 18 bonded to the opposed bottom of the truncated pyramidal cusps and, thus,. the matting layer itself. This fabric precludes the entry of insects, debris, and other unwanted elements when the laminate is used as a roof ridge vent construction. This fabric backing extends outwardly towards the "wing" portions 15 of the matting layer 11 and is bonded (preferably, heat bonded) to those outwardly extending, planar edge portions of the matting laye=- .
In a preferred embodiment, the matting layer 11 previously described is constructed from a series of nylon 6 macrofilaments which have a diameter of from about: 200 to about 1000 microns, preferably about 550 microns. These filaments form a planar mesh construction that takes the shape of the cusp structure, upon formation, as described above, wherein the cusps have a height of from about 0.25 inch to about 2 inches, preferably about 1 inch. The weight of the matting layer 11 can range about 30 to about 100 grams per square foot, preferably from about 50 to about 60 grams per square foot, with the preferred width of the laminate ranging from about 6 inches to about 15 inches, depending upon the roof shingle structure, but preferably will have a width of from about 10 to about 11 inches.
A suitable fabric 18 to use in the present laminate is available under the trademark COLBACK from Akzo Nobel Nonwovens Inc. and is preferably a bi-component yarn of polyester and nylon. A most preferred fabric has the following specifications: weight - about 100 grams per square meter; thickness - about 0.5 mm; tenacity - about 44 paunds per inch; elongation - about 34~; and apparent opening size (AOS) - about 40.
In a preferred embodiment, the matting layer has a hinge portion 19 which can be flexed to conform the product to the roof ridge of a roof as shown in Fig. 4.
The laminate described herein can be appropriately fastened to a roof deck and shingle portion 20 of the roof, over the ridge vent 21, using nails 22 (which will, of course, be hidden from view by the overlapping shingles 23 once they are installed) to allow for appropriate air flow (as shown by the arrows in Fig. 4) through the vent and through the matting layer 11 of the laminate so that the needed ventilation of the building's attic: or uppermost floor takes place. The cap shingles 23 are conventionally installed over the laminate with the "wing" portion of the laminate providing support.
The laminate of the present has a number of advantages over previous laminate constructions known to persons of ordinary skill in the art. The novel pyramidal structures of the matting layer, which make this product a "cuspated" rather than "non-cuspated"
AFP _-'i931 product, assist in affording the desired degree of noncampressibility to the product during such operations as the nailing of the structure to a roof of a building.
The c:uspated pyramidal structures do not impede the free flow of air through the present laminate since they are high7.y porous thereby distinguishing the present strucaure from the cuspated product sold under the trademark ROLL VENT 2. Since the fabric backing is supported on the exterior of the "cusps", it does not intrude into the inner structure of the present laminate so as to restrict the desired air flow through the laminate construction. In addition, having the smaller end of the novel pyramidal structures in contact with and direcaly attached to the backing material affords a surp=:ising degree of desired stiffness as compared to not having such a portion of that structure attached to that backing. The fabric backing in the present laminate, due to the presence of the outwardly extending, planar edge portion of that matting layer (a "wing" portion thereof) is mare protected from direct sunlight when the normal cap :shingle is installed over the laminate in the completed roof ridge vent. The fabric backing either may or may not be bonded to the surface of the outermost cusp at lEi in Fig. 4 and either may or may not lap over the top edge of the "wing" structure. Also, the laminate of the present invention provides a support for the edge of the normal shingle used in the roof ridge vent construction by means of the "wing" thereby precluding drooping of the shingle during extreme conditions of heat which would tend to cut off part of the desired air flow through the construction. The hinge area formed in the laminate of the present invention allows for flexing of AFP E~931 the 7.aminate construction so that it can be bent over the ridge of the roof without damage to the construction. The preferred thermal bonding to the matting layer to the backing material avoids the presence of glue which, in extreme heat conditions, could undesirably liquefy comp=-omising the bond between the matting layer and the backing. However, if desired, the bonding could be achieved by using glue or by using ultrasonic bonding, which some persons in the art consider as a form of thermal bonding.
The fabric backing, in a preferred embodiment, not only cove=:s the exposed areas on each end of the vent (end cap), but also covers the slot area of the roof, thereby preventing intrusion of undesired insects, debris, and othe=- items into the structure from within the attic.
The laminate of the present invention can be easily rolled and can be easily adjusted or aligned once installation of the laminate is a roof construction has begun .
The foregoing is provided for purposes of illusotration only and should not, for that reason, be used to construe the present invention in a limiting senses. The scope of protection sought is set forth in the Claims which follow.
