Abstract: A cover or the like consisting at least of one woven plastic web, provided at least on one side with a plastics foil, and for covers of comparatively large width composed of a number of such webs in either butted or slightly overlapping relationship. For reinforcement purposes, there is applied at least at two opposite sides an edge strip of similar, at least equally strong material as the cover. Spaced apart from the respective lateral edges, there are formed attachment holes, whereby a reinforcement cord in the longitudinal central region of the respective strip, substantially parallel to the respective lateral edge of the cover, is embedded between the edge strip and cover, while the said attachment holes are formed in the region inwardly adjoining the said reinforcement cord, through the edge strip and cover.

Abstract: A new process for making realistic appearing, simulated patchwork articles and a patchwork fabric configuration to be used therewith. In a preferred embodiment disclosed, a matrix of similarly sized, dimensionally aligned regions of design (14) is imprinted on a unitary piece of fabric (12).

Abstract: A carbon-filament reinforced gear material of laminated structure has layers of carbon filaments. The gear material includes a plurality of circular fabrics each having warps and wefts composed of a plurality of carbon filaments. The circular fabrics are laminated one on another such that the carbon filaments of their warps and wefts are substantially equiangularly spaced from those of another fabric about a common axis. The fabrics thus laminated are bound into a unitary structure by means of a binding agent of a thermosetting resin. A method for preparing the carbon-filament reinforced gear material includes the step of loosening the woven fabrics, each of which has such warps and wefts as are composed of the carbon filaments bundled into strands by means of a binding agent, by brushing the plain weave fabrics while applying thereto a binding agent so that the filaments in each of the strands may be substantially equidistantly separated from one another to make thinner and finer fabrics.

Each of the sheets is attached together to form the backing sheet and a plurality of apertures extend through the thickness of the sheets of polymeric and rubber material and are arranged over substantially the entire area of the latter sheets.

Such thermal barrier material is easily cut and stapled together to provide such a thermal shield or fire barrier of a desired configuration.

Abstract: A method is disclosed of forming a seam joining together two edges of a piece of fabric coated on one face with a water-impervious high frequency weldable plastics material, so as to form a water-impervious seam. In the method, the two edges are located together with the said coated faces facing outwardly, a binding strip is located over the said coated faces, the face of the binding strip in contact with the coated faces itself being coated with a high frequency activated material, and a radiofrequency field is applied to the seam to weld together adjacent said coated faces of the binding strip and the fabric. Certain forms of polyurethane and poly(vinyl chloride) are given as examples of high frequency activated materials. A novel seam is also disclosed.

Abstract: A lightweight composite fabric characterized by high retention of fiber content during initial laundering and exceptionally high strength as measured close to the edge of the fabric with cover and fabric aesthetics equivalent to conventional fabrics having 50% higher basis weight are produced by hydraulically needling short staple fibers and a substrate of continuous filaments formed into an ordered cross-directional array. The individual continuous filaments of the array are well spread and separated so that they have a spaced-apart relationship allowing interentangling of the short staple fibers with the continuous filaments to form more than about two reversals in the staple fibers per cm of staple fiber length between the faces of the fabric. The staple fibers have a linear density of less than about 0.3 tex per filament, are from about 0.5 cm to about 1 cm in length and comprise about 20% to about 50% of the weight of the composite fabric.

Abstract: A woven belting has a single-ply central portion and tubular edges which are integrally woven with the central portion as a hollow plain weave; high abrasion resistance is achieved for the tubular edges by shrinking their warp threads to a predetermined extent before the weaving operation. The warp threads in the edges of the belting are subsequently shrunk to their full possible extent during a final heat setting treatment of the whole belting.

Abstract: A seam between a pair of porous layers of sheet material includes a bead of cured nitrile latex material disposed on one side of one of the layers and extending transversely through the pores of both layers. The same is produced in its preferred form by first tensioning the juxtaposed layers, which are then clamped between a knife edge and a backup plate to define at least one lateral limit of the seam where the porosity is thus temporarily eliminated, after which liquid nitrile latex material is passed under pressure along the knife edge and toward the backup plate. The first layer filters out any latex film or cured particles or air bubbles which thus do not impair the integrity of the seam. The latex is then cured, and if desired, the sheet material is trimmed away at one side of the seam.

Abstract: A carpeting strip, method of making such strip, and carpet employing same are provided wherein such carpeting strip has integral joining means enabling the forming of a substantially invisible seam between an adjoining pair of carpeting strips upon providing a carpet employing such strips.

Abstract: Belting for safety belts, particularly for vehicles, having at least one side margin comprising an externally rounded protective profiled element, this element preferably being in the form of a tube. The belting, including said elements, may be woven in one piece. The warp threads in the woven tubular element preferably have a higher coefficient of elongation at break than those of the belt portion, so that under load they will not break before the warp threads of the belt portion. In order to achieve this, the warp threads of the woven tubular element may be shrunk before weaving.

Abstract: An additional, special warp thread system is woven into a web of woven material having a weft thread system and a warp thread system, the warp threads being arranged to have differing density in certain areas of the web for the purpose of increasing the structural rigidity. The additional warp thread system lies symmetrically with respect to the other warp thread system.
