1 mixing: the raw materials used for sticking and covering the polyester conveyor belt are mixed into semi-finished rubber compounds through the internal mixer for the use in the next process. In the preparation of rubber mixture, the equipment used are rubber breaker, mixer, plastic mixer, tablet press, etc.

Calendering: calendering is mainly used to complete the production process of canvas gluing, covering and other types. The main equipment includes four roll calender and cooler. The working temperature of the cooler is 15-25 ° C and that of the four roll calender is 50-80 ° C.

3 molding: at room temperature, the tape and cover rubber are rolled to form blanks by a molding machine to obtain semi-finished products.

Vulcanization: vulcanization equipment is a plane vulcanizing press. The plate temperature is 150 ℃. The semi-finished strips obtained by forming process are pressed and formed into finished products.

Inspection: the product is inspected according to the physical and appearance standards specified in the national standards.
