摘要： A carcass sleeve including a carcass ply and a pair of annular anchoring structures is fitted around a toroidal forming drum arranged in a first radially contracted operational condition. The carcass sleeve is toroidally shaped against a radially inner surface of an annular contrast element. The forming drum is positioned inside the carcass sleeve and is concurrently expanded towards a second operational condition. Upon reaching the second operational condition, the toroidally shaped carcass sleeve is coupled to the forming drum. The forming drum, coupled to the carcass sleeve, is adapted to be transferred in proximity of an application device of additional components externally to the carcass sleeve.

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： A process and a drum for looping annular anchoring structures in a process for building tyres for vehicle wheels includes: depositing a loop on a drum including a radially expandable/contractible intermediate annular portion and, in a position axially adjacent to the opposite axial ends of the intermediate annular portion, a pair of radially expandable/contractible lateral annular portions; associating an annular anchoring structure with a radially outer annular surface portion of the loop defined at the intermediate annular portion; and turning up each of opposite end edges of the loop on the annular anchoring structure through the lateral annular portions as a result of a thrusting stress imparted by a respective lateral annular portion of the pair of lateral annular portions because of a synchronous radial movement and a synchronous axial displacement of a respective plurality of circumferentially adjacent first angular sectors.

摘要： 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.

摘要： The present invention concerns a tire-building process in which a so-called "shaping" building drum is used and in which a ply turn-up bladder (2) is clamped on the outside of each bead recess (6) by an assembly of pallets (11) which can open in fan shape and cover the turn-up bladder completely in circumferential direction and in part in axial direction. The axial displacement of the said pallets (11), controlled by the axial displacements of two pistons (7) and (8), makes it possible to modify the shape of the ply turn-up bladder (2).

摘要： Bead wires 4 are set at both ends of a carcass ply 2, to form bead portions 5 and 5. Then, a carcass body 6a incorporated with a toroidal BT band 9 around the outer periphery portion is mounted on a forming drum 13 around which side rubbers 20 are mounted through bladders 16 and 17 at the positions corresponding to the bead portions 5 and 5. Thus, by expansion of the bladders 16 and 17, the side rubbers 20 are press-contacted with both the sides of the carcass body 6a.

摘要： A green tire forming apparatus has a driving section (2) and a forming section (1) supported by a shaft extended from the driving section (2). A center former section (10) of the forming section (1) has a pair of first former elements (11A), (11B) and a pair of second former elements (12A), (12B) arranged at the outside of the first former elements so as to be movable in an axial direction. The total width of the center former section can be shortened to about one fourth of the maximum. According to the apparatus, during green carcass formation, the width of the center former section (10) can be set as the required one, and during toroidal shaping, the width can be shortened to about one fourth of the maximum, whereby a distance (BW.sub.3) between beads can be made close to that of a metal mold. As a result, generation of wrinkles during tire formation is largely decreased and tire quality can be improved.
