PROBLEM TO BE SOLVED: To provide a method of manufacturing a fiber-reinforced layer for a conveyor belt, which suppresses an improvement in endless processing property and the disturbance and edge damage of the weft thereof during the manufacture while securing an appropriate trough property by reducing the density of the arrangement of the weft, and also to provide the fiber-reinforced layer for a conveyor belt.SOLUTION: In this fiber-reinforced layer, the density of the arrangement of the weft 3 is 5-15 pieces/5 cm, the cover factor of the weft 3 is 300-450, the cover factor of the fiber-reinforced layer 1 is 3,300 or less, the fineness of the weft 3 is 400-1,400 dtex, and the lateral both ends of the fiber-reinforced layer 1 are formed in a tack-in structure. When a heat treatment is performed while the fiber-reinforced layer 1 is fed in the warp direction after being dipped in an adhesive liquid, the lateral both ends of the fiber-reinforced layer 1 formed in the tack-in structure are held by clamps 8, a tension of 0.035 cN/dtex or below is applied thereto in the warp direction, and the movement of the fiber-reinforced layer 1 in the weft direction is restrained, whereby the bending of the texture thereof after the heat treatment is 0-0.5%. |
