PROCESS AND APPARATUS FOR MANUFACTURING PNEUMATIC TIRES

摘要

Process and apparatus for manufacturing a pneumatic tire comprising a carcass (1) already shaped in the form of a cylindrical tube having carcass piles faithfully deformed around the base and the sides of the bead cores (2). The drum for torically shaping the carcass comprises means for receiving by telescoping the carcass tube (1) and opposite sectors (10, 13) for clamping between them the portions of plies deformed around the bead cores (2). The characteristics of the spaping drum permit automatic loading of the carcass tube (1) and a subsequent toric shaping in absence of sliding of the cords of the plies arranged around the bead cores (2).
