Abstract: A method of forming a high tensile strength, reinforced, seamless, large cylindrical casing wherein a metal such as nickel is electrodeposited in conjunction with reinforcing materials such as carbon fibers to form a matrix on the outer surface of a rubber layer, the surface of which has been rendered electroconductive, deposited on a mandrel but separated therefrom by a separating material, such as wax, which will permit ready separation of the finished casing product from the mandrel when by heating the latter until the separating material melts or liquefies.

Abstract: Process for making a synthetic suede product, two rolls at a time, each roll consisting of a web of fibrous material, to the upper side of which is attached outwardly extending polyurethane fibers. The process consists of continuously feeding two thin films of polyurethane into the nips formed by two rotating heated cylinders wherein the two feed materials are forced into two flexible molding bands provided with a multiplicity of molding cavities by pressing the film against a heated silicone roller. Most of the urethane film fills the cavities and forms a fibrous surface when removed, leaving a very thin layer in molten state which becomes glued to the upper layers of fibrous webs which are passed into a second set of nips formed by two rotating heated cylinders. The fibrous material or fabric may be man-made such preformed woven, knitted, foamed, non-woven, spun bonded, spun laced, etc.

Abstract: Process for preparing a synthetic suede product from three or more separate layers of non-fibrous materials welded together: two outer layers with outwardly extending polyurethane fibers and at least one inner layer of polyurethane film, sheet, web, or foam. The process comprises continuously feeding at least three separate films, sheets or webs of the appropriate non-fibrous feed materials into the nip formed by two rotating, heated cylinders wherein the feed materials are contacted under pressure with two heated flexible molding bands provided with a multiplicity of molding cavities whereby outwardly extending fibrous polyurethane surfaces are formed and wherein the separate layers are welded together. The novel synthetic suede product obtained by this process is also disclosed and claimed.

Abstract: The use of carding technology to produce a patterned sheet of thermoplastic material which comprises pressing thermoplastic sheet material between rotating cylinders, rollers or endless belts covered with card clothing having a surface of metallic wires. The rotating carding means are provided with internal heating means for maintaining the surface wires at elevated temperatures.
