In order to improve the winding quality of tire tread winding production line equipment and the stability of tape distribution

reduce the research and development cost and waste rate. Based on the theory of B-spline curve

an algorithm for calculating the change of tire cross-section is presented by studying the winding process of rubber strip during the winding of tread winding machine of construction machinery tire. The accurate mathematical description of the current tire tread winding process is made

and the precise control of the shape and position of the tire tread and the rubber strip during the tire tread winding process is realized. Experimental results show that the proposed method can effectively improve the winding precision of tire tread. It is concluded that the proposed method can enhance the adaptability

accuracy and stability of tire production process modification.
