METHOD AND APPARATUS FOR CORRECTING SHAPE OF RESIN BELT CONVEYOR

摘要

PROBLEM TO BE SOLVED: To provide a method for correcting the shape trouble such as an undulated shape or warpage in the belt side part or belt central part of a resin conveyor belt without exerting an effect on a resin layer to reduce the percent defective of the resin conveyor belt. SOLUTION: In a method for correcting the shape of the resin conveyor belt 1 wherein core canvas 2 and the resin layer 3 are laminated, the resin conveyor belt 1 is heated from the side of the core canvas 2 to a temperature 10-20°C lower than the melting point of the resin layer 3 and brought into contact with a cooling roll on the side of the core canvas 2 in a state that a tension of 0.5-2.0 kN/m is applied to the resin conveyor belt 1 not only to be cooled but also to be corrected in shape.
