(54) CONVEYOR BELT

(57) The invention relates to conveyor belts. The goal is to increase the reliability of

the expense of reducing tarpaulin wear. The tape includes the plates and fabric pads. The warp threads 5 of the side parts 7 of the fabric linings are made of individual segments 8 During the operation of the ribbon onboard 10, it is worn out, and the warp yarns of the warp 5 are exposed, segments 8 of which are easily separated separately without winding onto conveyor rollers. This reduces wear on the belt and rollers 2 or less.

The invention relates to transport equipment, namely to conveyor belts.

The purpose of the invention is to increase reliability by reducing tape wear.

FIG. 1 shows a cross section of the tape; in fig. 2 - the same, top view on the side of the gasket without lining.

The conveyor belt 1 consists of fabric linings 2, between which rubber layer 3 is placed, and rubber liners 4. Each fabric strip 2 includes warp threads 5 located along the longitudinal axis of the tape and weft threads 6 located perpendicularly. In the side parts 7 of the tape on both sides for a certain width from the edge of the tape, the warp threads are made in the form of individual segments 8 of relatively small length arranged one after the other. The mating sites 9 segments of 8 adjacent warp threads are displaced in length relative to each other with the possibility of overcoating. The tape also has boards 10c on each side and a middle part 11. During operation, the ribbons of the board 10 wear out and strip the warp threads 5, weft b and stitching threads (conventionally not shown). Further, the wear process leads to the destruction of the levity threads, the partial destruction of weft threads 6 and the release of the warp threads 5 In connection with the warp threads in the side pieces made as separate short pieces 8, they fall out as they are released and do not wear tape and rollers due to winding of the threads on the rollers. The transmission by force of the threads of the base 5 of the side parts is similar to the work of the joint of the rubber cable made with the installation of cables. T force here is transmitted from one length of 8 strands to the adjacent through rubber layer. The length of the conjugation of the warp threads 5 is 100-150 mm. This determines the possible length of segment 8, equal to 200-300 mm while ensuring 75-80% of the strength of the side part relative to the middle part of the tape.
