Abstract: In the production of irregular non-woven material sheets of synthetic filaments, the warp from spinnerets is drawn off by means of a draw-off device and then deposited on a substrate. To avoid tangling of the individual filaments, they are guided along a nozzle wall formed by slot nozzles stacked on top of each other and forming a draw-off device. The slot nozzles as well as the air compressor are operated polytropically. The deposit of the warp on the substrate is accomplished by a flip-flop cross winding.

Abstract: A deep drawing molding process for the formation of shaped plastic elements in which a certain thickness of the thermoplastic sheet to be formed is heated to the plastic flow state while an embossed or decorated outer side of the sheet is maintained at a temperature below the plastic state by means of a cooling air stream. The plastic element producted has an undamaged decorated side and improved wear properties such that it may be used in high ambient temperature applications, such as automobile dashboards, without cracking. The apparatus for heating and forming the plastic element includes a clamping frame to hold the sheet, a heating element disposed above the sheet, a molding box below the frame, which box is provided with inlets and outlets for cooling air and the application of vacuum, and a moldign tool also disposed above said frame, which is forced through said frame and against said sheet when a certain thickness of the sheet has been heated to the desired plastic flow temperature.

Abstract: A substrate having an appearance similar to that of nubuk-leather or pile-leather, respectively, or of a textile pile consists of a textile carrier body being at least partially impregnated with a, preferably cross-linked, polymeric synthetic plastics material consisting of a foam which has open cells formed by introducing air and optionally has closed cells formed of hollow microspheres. The textile carrier body consists of a fleece or of a knitting, preferably of a crimped fleece of synthetic fibres, which is needled together with a knitting or with a fleece, strengthened by thermal embossing, in such a manner that the fibres extend through the knitting. The knitting may consist of a roughened stockinet, i.e. a stockinet having opened loops. The carrier body is ground at least at its one impregnated surface and is thus rough and can be provided with a coating.

Abstract: A process for improving the embossing properties of foamed sheets on a PVC basis including the steps of (1) treating the foamed sheets with a lacquer solution of 10 to 20% by weight of a resin in 4 to 10% by weight of a lacquer solvent having a boiling point greater than 190.degree. C., and in 70 to 86% by weight of a lower boiling point organic solvent; (2) drying the lacquer treated sheet at temperatures ranging from 70.degree. to 100.degree. C.; and (3) embossing said dryed sheet at temperatures greater than 200.degree. C.

Abstract: In a baffle tray for a fiber distributor, the tray has opposite curved walls, the lower edges of which of their midpoints are each provided with an arcuate recess to aid in uniform formation of a fleece.

Abstract: Leather sheets having desired grain pattern are mounted on a roller with edges abutting. Onto the surface of the grain pattern a silicone synthetic resin is applied as a uniformly thick coating with a coating knife as the roller rotates. The resin is hardened into a matrix. It is then peeled off the grain pattern. The grain pattern in the matrix is interrupted where the leather sheets abutted. The matrix is placed with the pattern outward on a roller whose diameter pretty much matches the diameter of the embossing roller to be produced. The surface of a tubular thermoplastic film is embossed by contact with the cylindrical matrix under heat and pressure. The embossed surface of the thermoplastic film is once again overembossed under heat and pressure in the areas along the abutting edges of the natural grain pattern on the roller, so that an endless positive impression without seams in the grain's pattern is produced.

Abstract: A plastic film made from polyvinyl chloride homopolymers and/or copolymers that is produced with the use of olefinic unsaturated monomers is disclosed that includes a plasticizing agent and a thermoplastic rubber. The plastic film has high strength, behaves like rubber and has improved aging properties and low temperature properties. External softening is not necessary to obtain elastic properties.

Abstract: A method for producing the matrix for the embossing cylinder which has a uniform pattern design in the marginal areas adjoining the abutment where the ends of the blanket are joined to form the tube comprising (1) casting liquid silicone rubber on a sheet of leather having the desired grain and vulcanizing the silicone, (2) using the matrix thus formed to emboss, under heat and pressure in a press, a rectangular sheet of thermoplastic resin such as polyvinyl chloride film, (3) forming the embossed sheet into a tube, (4) placing the portion of the tube having abutting edges in a narrow platen press and reembossing the area surrounding the abutment with the silicone rubber matrix to mask the impression of the joint and provide a continuous uninterrupted pattern, and (5) using the positively-embossed thermoplastic sheet as a matrix for casting vulcanizable silicone rubber to form a negatively-embossed matrix for use as a blanket on an embossing roll.

Abstract: A method of producing a surface connection or bond between two surfaces, the first surface being at least partially formed of polypropylene and the second surface being formed of a dissimilar material, wherein the second surface is laminated with a textile surface structure formed predominantly of polypropylene fibres, the thus laminated second surface and the first surface then being connected to one another by the application of heat and pressure.

Abstract: A composite flat structure having a high degree of absorption for medical and hygiene purposes, the structure comprising at least two layers having differing moisture absorption characteristics. One of the layers is a cover layer comprised of a composite synthetic bonding agent-free non-woven fibre and another of the layers is a storage layer located below the cover layer. The storage layer has a higher degree of moisture absorption than the cover layer which has such a degree of moisture absorption that, after adaptation to normal climate in accordance with DIN 53 802, it has a moisture content of less than 6% relative to its dry weight in accordance with DIN 53 800. The surface of the fibres of the cover layer is capable of being wetted by the liquids to be absorbed.
