WOVEN FRAME OF SINGLE-PIECE CONVEYOR BELT WITH ELASTOMER COATING Russian patent published in 2020 - IPC D03D3/04 D03D11/00 

FIELD: textile industry.

SUBSTANCE: invention relates to the textile industry. Woven framework of conveyor belt comprises two parallel woven structures of the same interlacing with number of layers of not less than two, displaced relative to each other on one or two level layers and connected together by weft threads in the zone of one of peripheral layer layers. Ratio of linear densities of woven warp yarn and weft is in range from 1.0 to 4.0. Proposed woven frame in comparison with the analogues has a breaking load on the weft which is not less than 50 % of the breaking load on the warp yarn, which ensures qualitative and reliable joining of the ends of the conveyor belt, which excludes the sliding and subsequent destruction of the mechanical docking sutures. Besides, the design of the proposed woven frame provides a higher degree of troughing and strength of bonding with the coating (in particular, with rubber 5.5–7.2 kgf/cm), and on all other parameters corresponds to the requirements for woven frames of conveyor belts.

EFFECT: invention can be used for production of single-piece conveyor belts with elastomer coating, mainly rubber-fabric conveyor belts used in transportation of rock mass.
