METHOD FOR MANUFACTURE OF HOLLOW MULTILAYER WOVEN INTERMEDIATE PRODUCT Russian patent published in 1994 - IPC

FIELD: production of reinforcing materials in structures of complicated forms maximum close to spherical and made of composite materials. SUBSTANCE: warp yarns are drawn-in on loom, chord of segment section is placed parallel to loom shed. Process of forming contour of intermediate product is carried out, first, with minimum width of loom shed by reed by introduction of warp yarns to obtain maximum width of loom shed by reed with subsequent withdrawal of warp yarn to provide for minimum width of loom shed by reed. When intermediate product is made on jacquard machines, direction of laying of weft yarn for reverse is changed with respect to that adopted at the stage of introduction of warp yarns in formation of contour. EFFECT: higher efficiency. 6 dwg, 3 tbl
