[0002] As we all know, in the field of tire manufacturing, the tire production process mainly includes four main steps: mixing process, calendering and extrusion process, molding process and vulcanization process. However, due to the large size of large-scale engineering radial giant tires and the wide and thick components, the height difference between the layers of various components is difficult to press into place during the layer bonding process, which easily leads to bubbles and radial cracks. In particular, the thickness of the single piece of film and inner liner components ranges from 3 to 20 mm. There is a height difference at the edge during layer bonding, which leads to bubbles that affect the air tightness and elasticity of the tire. In severe cases, radial cracks will occur, thereby affecting the load-bearing capacity and wear resistance of the tire, seriously affecting the performance and safety of the tire, and to a certain extent increasing the cost of use and maintenance. Summary of the Invention
