PROBLEM TO BE SOLVED: To provide a dip working method of a conveyor belt capable of obtaining a reinforcing fabric of high strength by executing the cooling treatment of the reinforcing texture with polyester fiber and nylon 66 fiber being used for warp by providing a cooling step between a heat-setting step and a normalizing step. SOLUTION: A working treatment step of a reinforcing fabric dipped with liquid adhesive includes a first dry step 7, a heat-setting step 8, a cooling step 9, and a normalizing step 10. In the cooling step, the reinforcing fabric is continuously cooled under the atmosphere of 5-50°C for≥50 seconds. Further, in the heat-setting step 8, the reinforcing fabric is passed under the atmosphere of 180-200°C for 40-100 seconds. In the normalizing step, the reinforcing fabric is passed for working under the atmosphere of 200-220°C for 40-100 seconds. COPYRIGHT: (C)2011,JPO&INPIT
