ABSTRACT:
Device and process for constructing a carcass and for preshaping an unvulcanized rubber tire includes a preshaping device. An axially adjustable hollow, cylindrical body associated with the preshaping device has a radially outermost surface. An adjustment device capable of adjusting an axial position of the cylindrical body between an operating position and a rest position is provided. A second body having a radially outermost surface is adapted to form a substantially cylindrical, sealed construction surface with the radially outermost surface of the cylindrical body in the operating position. The preshaping device, in the operating position, is positioned axially inside the cylindrical body in a same axial position as the cylindrical body to enable positioning the carcass without the carcass being affected by the preshaping device. The preshaping device, in the rest position, is positioned axially outside the cylindrical body to enable preshaping of tires without the preshaping of the tires being affected by the cylindrical body. The process includes positioning a cylindrical drum surface to at least partially surround a preshaping device, assembling a carcass on the cylindrical drum surface radially outside the preshaping device, sliding at least a part of the cylindrical drum surface to an axial position beyond the preshaping device, and shaping the assembled carcass by using the preshaping device.
