う問題があった。Conventional conveyor belts made of rubber or resin. In flat belts, canvas woven from fiber threads or resin sheets are usually used as the tensile material, and one or more layers of rubber are used as the tensile material. Embedded in resin,
When joining these ends of the belt, the cover rubber and resin at the top and bottom of both ends of the belt are cut off to a predetermined length necessary for joining, and the tensile canvas and resin sheet 11 are exposed. A bonding method is used in which the upper and lower canvas sheets or resin sheets are laminated in a stepwise manner, and then a predetermined amount of unvulcanized rubber or resin is laminated on the upper and lower surfaces and heated under pressure. The opening of the warp and weft of the canvas is small, and there is no opening of the resin sheet at all, making the canvas unique.
Since the surfaces of the resins are bonded to each other, sufficient adhesion force cannot be obtained, resulting in a decrease in joint efficiency, and in the case of resin sheets, there is a problem that the rigidity is relatively high and the flexibility is decreased. Ta.

張体樹脂シートを強固に接着せしめる方法にある。In view of the above circumstances, the present invention aims to improve the adhesive strength, joint efficiency, and flexibility of the belt joint by using a porous resin sheet as the tensile member, and has the following characteristics: However, a porous resin sheet is embedded in rubber or resin to create a structure with high adhesive strength for the belt itself, and when the belt is joined, the resin sheets at both ends of the belt are laminated so that the pores are aligned, and then the joint is bonded. There is a method in which the rubber and resin (hereinafter simply referred to as rubber) coated on the tensile resin sheet are communicated and integrated through the pores, and the rubber and the tensile resin sheet are firmly bonded by an anchoring effect.
