摘要： A process and an apparatus for building tyres, wherein, in the process, a carcass sleeve including at least one carcass ply and a pair of annular anchoring structures is transferred to a shaping drum including flange elements that are each engageable with one of said annular anchoring structures. The carcass sleeve is shaped according to a toroidal configuration by means of mutual axial approaching of the flange elements. Before shaping, annular grip elements respectively carried by the flange elements are radially expanded, each inside one of the annular anchoring structures, in order to engage the carcass sleeve. The annular anchoring structures are moved axially apart from each other before engaging the carcass sleeve by means of the annular grip elements.

摘要： A carcass sleeve is situated in a radially external position with respect to a toroidal forming drum, arranged in a first radially contracted operative condition. The carcass sleeve is shaped according to a toroidal configuration while the forming drum is positioned inside the carcass sleeve. During shaping of the carcass sleeve, the forming drum is radially expanded up to a second radially expanded operative condition. Upon completed shaping, the carcass sleeve is coupled to the forming drum in the second operative condition. The forming drum, coupled to the shaped carcass sleeve, is arranged in proximity to at least one device for building at least one belt layer at a radially external position relative to the shaped carcass sleeve.

摘要： The invention is related to a process and an apparatus for building tyres. In the process a carcass sleeve (11) comprising at least one carcass ply (3) and a pair of annular anchoring structures (5) is transferred to a shaping drum (14) comprising flange elements (16a, 16h) that are each engageable to one of said annular anchoring structures (5). The carcass sleeve (11) is shaped according to a toroidal configuration by means of mutual axial approaching of the flange elements (16a, 16b). Before shaping, annular grip elements (36) respectively carried by the flange elements (16a, 16b) are radially expanded each inside one of the annular anchoring structures (5) in order to engage the carcass sleeve (11). The annular anchoring structures (5) are moved axially apart from each other before engaging the carcass sleeve (11) by means of the annular grip elements (36).

摘要： A toroidal forming drum and a process for budding tyres. The toroidal forming drum is expanded within a shaped carcass sleeve for supporting the carcass sleeve against an abutment surface externally provided by the forming drum. An elementary semi--finished product is applied around the shaped carcass sleeve by pressing the elementary semi-finished product toward the abutment surface. The abutment surface has circumferential rows of solid portions alternated with hollow portions. The solid portions, arranged along axially opposite circumferential edges of the abutment surface, have a transverse size between 10% and 60% of a transverse size presented by the solid portions arranged in proximity to an axial centreline plane of the abutment surface.
