In recent years, with the rapid development of automobile industry, it generates a lot of waste tire each year[4].Main raw material of tire is natural rubber, and in order to improve the service life of tire, the existing tire in the production process is added a variety of additives, especially the cord fabric layer, whose wear resistance and fatigue resistance has been greatly improved, and has a certain elasticity and strength because of the addition of nylon and other materials.
Based on the above analysis, the use of cord fabric layer in waste tires in the made of leaf-peeling component has certain feasibility. 1 Test equipment ,material and method 1.1 Test equipment The test uses the whole sugarcane harvester produced in cooperation with a company in Guangxi, showed in Figure 1-1.
