Abstract

A tire forming machine is provided which includes a forming drum having a central drum portion arranged at an axially central location of the forming drum, and right and left drum portions which are arranged on either of the right and left sides of the central drum portion and which are movable in an axial direction of the forming drum. At the time of winding tire-forming materials on the forming drum to assemble a carcass, the right and left drum portions are brought into contact with the central drum portion and stuck with the same to cooperatively form a continuous surface. After the assembly of the carcass, the right and left drum portions are moved to respective bead setting positions to open the forming drum. The thus-constructed tire forming machine is comprised of a plurality of gripping mechanisms arranged around the central drum portion of the forming drum for gripping an axially central portion of the carcass.
