The rubber machine plays a crucial role in the tire manufacturing process by laminating different components such as rubber curtains, wire loops, and treads into a green tire. Depending on its application, it can be categorized into two main types: the conventional tire building machine and the radial tire building machine. In the case of conventional tires, each layer of the carcass cord is laid at an angle, typically oblique. During the forming process, the cord cylinder is first placed onto the forming drum, followed by the placement of steel wire rings on both sides. The cushion layer and tread rubber are then applied in the middle, resulting in a cylindrical-shaped green tire. Radial tires differ significantly from conventional ones, primarily in the orientation of the buffer layer cords. These cords are positioned at an angle of approximately 90° to 75° relative to the axis of the carcass, making them nearly perpendicular. This arrangement prevents significant changes in the diameter of the buffer layer after molding. As a result, the carcass must be expanded to a near-final shape before the buffer layer is added. This structural difference leads to a distinct design in radial tire building machines compared to their conventional counterparts. The entire process of forming a radial tire using a single machine is known as the one-step molding method. Alternatively, if the carcass is first produced using a modified conventional tire building machine and then molded on a radial tire forming machine, this is referred to as the two-stage forming method. Both techniques have their own advantages and are used based on production requirements, efficiency, and quality control considerations.
