Flat belt NO.1,Characteristics Common flat rubber belt, also called transmission belt, ususlly uses high quality cotton canvas as its skeleton layers Afeer the surface of the canvas as its skeleton layers. Afeer the surface of the canvas is scrubbed and coated with approprite rubber , several layers of rubber canvas adhere together to from the belt , enclosing rubber is used to make the seam firmer, and better adhered together better. The flat rubber belt has the characteristics of high strength ,good flexibility, and small elongation, It is mainly used in factories, mines ,docks , metallurgical industry , and also widely used in ordinary mechanical power transmission , great power processing of grains like rice and wheat . irrigation equipment , wood cutting and other power transmitting equipment for industry and agriculture. Therefore is plays more and more important role in various types of power tranmitting equipment. Flat belt No.2, Product classification 1. Cut edge flat rubber belt is manufatured by adhering several layers of full width canvas together ,the sides of the belt are formed by cutting , the belt edge surfaces are coated with rubber paste. 2. Fold edge Fold edge flat rubber belt is folded by the outer ply or plies of canvas , and the sides of the belts are round. Flat belt NO.3 ,physical property elongation at break :in vertical tensile test ,the elongation at break shoud not exceed 20% adhesion strength :adhesion between flat belt layers is no less than 3.0 n/m.
