Abstract

The present technology provides a conveyor belt. An upper cover rubber and a lower cover rubber are respectively disposed above and below a core layer so as to sandwich the core layer, which core layer is composed of a plurality of steel cords extending side by side in parallel. The outer diameter of the steel cords is not less than 0.35 mm and not greater than 6.0 mm, and the side-by-side pitch P of the steel cords is greater than 0.35 mm and not greater than 7.0 mm. The steel cords are embedded extending in the longitudinal direction of the conveyor belt.

First claim

The invention claimed is:

1. A conveyor belt comprising a core layer composed of a plurality of steel cords extending side by side in parallel, and an upper cover rubber and a lower cover rubber respectively disposed above and below the core layer so as to sandwich the core layer, the steel cords being embedded in the core layer extending in a longitudinal direction;
an outer diameter of the steel cords being not less than 0.35 mm and not greater than 6.0 mm, and a side-by-side pitch of the steel cords being greater than 0.35 mm and not greater than 7.0 mm, and
wherein weft threads of resin fibers are provided passing vertically in a stitched manner between the steel cords arranged side by side in parallel so as to traverse the steel cords, and the weft threads are disposed with a spacing set to not less than 16 mm and not greater than 500 mm in a longitudinal direction of the steel cords.

2. The conveyor belt according to claim 1 , wherein a structure of the steel cords is any one cord configuration from among cords with a 1+6 configuration, cords with a 3+6 configuration, cords with a 1+19 configuration, and cords with a 1+Sew (19) configuration, and a twist multiple of the steel cords is not less than 9 and not greater than 14.

3. The conveyor belt according to claim 1 , wherein the weft threads are constituted by weaving a plurality of long fibers, and a fineness is not less than 300 decitex and not greater than 5000 decitex.

4. The conveyor belt according to claim 2 , wherein the weft threads are constituted by weaving a plurality of long fibers, and a fineness is not less than 300 decitex and not greater than 5000 decitex.
