ONE-PIECE WOVEN CARCASS OF CONVEYOR BELT Russian patent published in 2002 - IPC

FIELD: textile industry. SUBSTANCE: carcass has two identically woven parallel structures laid onto one another in at least two integrally connected layers made from weft and warp threads. Layers are bound by means of two additional pressing bases having threads alternately interwoven with adjacent rows of weft layers and extending in each weft row from lower innermost layer to upper innermost and from lower outermost layer to upper outermost layer. Threads of one pressing base are interwoven with additional weft threads so as to form layers between adjacent weft rows on outer surfaces of woven structures. Layers on one of outer surfaces within pattern repeat are formed with the use of weft thread carried out onto surface from one of weft rows, which are interwoven through threads of this pressing base. Linear density of main base threads is substantially greater than linear density of threads of additional pressing bases. Carcass of such construction is employed as low combustibility, hyperstrong conveyor belt used in mine shafts. EFFECT: improved tensile strength, low deformation at working loads, high adhesion to polymeric material. 4 cl, 1 dwg
