METHOD AND APPARATUS FOR MANUFACTURE OF TUBULAR PLAITED PRODUCTS

FIELD: textile and other related branches of industry, in particular, production of tubular reinforced articles, such as curved water ducts, branch pipes, adapters and other products of different shape. SUBSTANCE: method involves manufacturing products from composite materials on the base of high-strength and light filaments of fiber glass and polymeric binder; providing diagonal plaiting of filaments. Apparatus has table divided into two concentric circular sections which are positioned for effectuating periodical reciprocations. Table sections are provided with radial slots, with number of slots being equal to number of spools. Spools are displaced by movable table sections and pushers arranged in two groups, one group disposed outside outer circular table section and other group disposed within smaller circular table section. Camshaft gear may be used as pusher. Spools are periodically moved in tangential direction through one pitch with following displacement in radial direction: one group toward another group, with further repeating of cycle. Article produced possesses increased flexibility and elasticity due to diagonal plaiting, with plait cell being movable. Plaited products have large diameter of up to 50-100 mm and thickness of up to 3-5 mm, of monolithic structure. EFFECT: wider operational capabilities, wider range of products, simplified method and construction. 4 cl, 1 dwg
