Abstract: Wire reinforced paper products wherein wires are affixed to a paper layer or included within a paper structure with at least one paper layer conforming to the contour of the wires to supplement the rigidity produced by the wires and a corrugated paper structure including wires disposed therein. The paper products are manufactured in continuous processes which enable the use of one or two sets of parallel wires, the latter producing a wire grid structure. In the manufacture of corrugated structures one or two sets of wires may be included in the corrugated portion and the overlying layer or layers and in so doing the structural strength and moisture resistant characteristics of the resultant corrugated board may be increased several fold without materially increasing the cost of the board as compared with board using relatively heavy paper in order to achieve increased strength.

Abstract: A fire-retardant sheet comprising superposed layers including a plastic material with a metal foil on one side and a further plastic sheet or layer laminated thereto with the interposition of a wire mesh.

Abstract: A composite web comprises a film of plastics or other material laminated to a reinforcing layer formed by a network of tapes which extend in zigzag fashion back and forth across the laminating film with their points of reversal within the confines of the film edges so as to be covered by the film. If there are two equally wide laminating films, one on each face of the reinforcing tape layer, the films may be offset to overlap one another laterally and the width of the tape layer exceeds that of each film by the amount of overlap, whereby the points of reversal of the tapes are covered by one of the films along one longitudinal edge of the web and by the other film along the other longitudinal edge of the web.

Abstract: The invention relates to a floor and/or wall covering, its manufacturing process, as well as to an installation for performing this process.It specifically relates to a non-woven floor and/or wall covering having at least one layer of parallel juxtaposed textile threads and a supporting layer to which are individually fixed various textile threads.Particular applications of the invention are to all types of floor and wall coverings and to furnishing fabrics.

Abstract: Dimensional stability of melamine decorative laminates is improved by a pair of spaced, foraminous steel foil layers, which resist shrinkage of the melamine layer. Steel foil layers are also used to prevent splitting of low-strength wallboard cores as a result of shrinkage of melamine facings, and each facing need have only a single steel foil layer in the case of a wallboard.

Abstract: A highly absorbent and fragile composite sheet normally used as a throwaway domestic wiper is quickly and easily converted to a strong and attractive colored wallcovering. Thus, a composite layer comprising a net material sandwiched between and bonded to a pair of cellulosic-fleece (wadding) layers has a carrier sheet of paper bonded thereto, has colorant applied thereto, and is impregnated with a synthetic resinous bonding medium so that the fleece layers are bonded together at the mesh openings of the net material. In a preferred construction, the carrier sheet of paper has an internal cohesion inferior to that of the composite layer so that with the covering on the wall the composite layer is peelable from the carrier sheet adhering to the wall.

Abstract: Process for forming a scrim-reinforced film wherein a molten, film-forming plastic, such as polyethylene, in a high state of fluidity is fed onto an unsupported scrim and solidified by cooling to produce a scrim at least substantially completely enclosed and surrounded by the plastic. The film, thus produced, can be formed into a high strength bag container by a folding and cutting operation utilizing hot knife means capable of fusing and thus sealing the plastic. In a preferred embodiment, the plastic is extruded onto the scrim and is subsequently heat shrunk to cause the scrim fibers to buckle and give the appearance and feel as well as the strength of a reinforced material.

Abstract: A flexible camouflage base material includes three layers, one being a layer of non-woven, flexible, electrically nonconductive polymeric material, a second layer of substantially identical material, and a third layer lying between the first two, the third layer having two sets of strands, the first and second layers being bonded to the third layer and to each other through openings in the third layer. The third layer includes a first array of strands spun from polyamide or polyester fibers and electrically conductive fibers, such as stainless steel or graphite, the strands being arranged in parallel relationship with each other and lying in a plane parallel to the first and second layer. The third layer also includes an adjacent array of strands of the same nature as the first array, the strands of the second array being disposed at an angle to the first to form a plurality of parallelogram-shaped openings. The larger angles of the parrallelograms thus formed are between about 100.degree. and about 105.

Abstract: A golf shaft and its method of fabrication. The shaft comprises a tapered, scrolled, oblong blank of thin laminated sheet material having alternating laminae of woven glass fabric and resin impregnated unidirectional graphite fibers. The fibers are arranged in a predetermined specific angle of orientation with respect to the longitudinal axis of the shaft.

Abstract: A reinforced matting of melt-spun, interlooped, substantially amorphous and continuous synthetic thermoplastic filaments of which one set of filaments is applied with random penetration to a flat, latticed structure such as a fabric mesh or wire screen while another set of filaments may be added to form at least one and preferably several additional rows of interlooped filaments adhered to the first set of filaments carried by the latticed structure as a reinforcing member.

Abstract: In a process for forming a nonwoven reinforced cellulosic material, for use in applications such as wipes and disposable clothing, which comprises applying adhesive to a ply of nonwoven scrim, bringing at least one cellulosic ply into contact with the scrim to form a substantially unbonded laminate, the improvement comprising applying pressure to discrete regions of said substantially unbonded laminate while said adhesive is in an activated condition. The application of pressure to discrete regions achieves ply attachment at only intermittent points on the scrim and can also serve to provide an embossed laminate texture. The product so formed is strong and has desirable absorbency, texture, bulk, hand and limpness.

Abstract: The present invention relates to a method of and apparatus for manufacturing a net of non-woven threads, in which first and second laps of parallel threads, are drawn off, respectively, from a fixed creel and a rotary creel with the first lap longitudinal and the second lap transverse and wound about the first lap. The threads of the second laps are severed at each of two opposed longitudinal edges of the first lap and the net formed by part at least of the longitudinal threads of the first lap and those pieces of the transverse threads of the second lap which are situated on one and the same side of the first lap is collected and stabilized, while there is effected relative running ahead of the longitudinal threads which increases progressively from one thread to the next in relation to one of said edges, from the latter up to the other edge.
