PROCESS AND APPARATUS FOR MAKING BELT MEMBER OF PNEUMATIC RADIAL TIRE

摘要

PROBLEM TO BE SOLVED: To solve troubles such as the stock spaces of the belt member for every specification of a tire and scraps of member and realize an efficient multikind and small quantity production. SOLUTION: A rubber-covered cord (c) is successively and spirally wound around a winding drum D by the length corresponding to the peripheral length of a belt so as to locate the winding starting end and the winding ending end of the cord on the axially extending cutting line on the winding drum D in order to produce a cylinder formed by spirally arranging the rubber-covered cord (c) on the winding drum D. Next, the cylinder is cut along the cutting line so as to remove the cut cylinder from the winding drum in order to develop the cut cylinder into a flat plane so as to obtain a belt member.
