摘要： In the method for producing a tire carcass ply for a vehicle, the ply is wound onto a drum and contains reinforcements running in planes that are radial to an axis of the drum, of which: at least one assembly member (51, 52) mounted such that it can move in relation to the drum brings the ends of the ply together and assembles them by travelling over the ply in a direction (X) parallel to the ends; and prior to assembly, a blade independent of the one or of each assembly member extends between the drum and the ends without extending between the drum and the rest of the ply.

摘要： A plurality of strip-like elements is applied onto a forming drum externally having a substantially cylindrical laying surface. The strip-like elements are disposed in mutually approached relationship to form at least one first annular reinforcing layer on the forming drum itself set to a first work diameter at which each of the applied strip-like elements on the laying surface subtends an arc of a circumference of a width as large as a submultiple integer of the overall circumferential extension of the laying surface itself. Adjustment devices operating on the forming drum subsequently carry out expansion of the latter to a second work diameter larger than the first work diameter, while maintaining its laying surface substantially cylindrical.

摘要： A method of building a tire onto a tire building drum is described. The method includes the steps of: applying one or more tire building components onto the drum to form a tire carcass having carcass ends; wherein the drum has an inboard section, a center section and an outboard section. The inboard section has a rotating spindle and a sliding shaft, wherein the sliding shaft is slidable within the spindle. The inboard section has a radially expandable bead lock mounted on the spindle, said center section mounted to a hub, wherein the hub is mounted on the sliding shaft. The center section has a plurality of tiles mounted thereon that are radially expandable, wherein the outboard section of the drum is mounted on a distal end of the sliding shaft, wherein the outboard section further has a radially expandable bead lock; wherein the center section and the outboard section are axially movable by sliding of the sliding shaft. The method further includes the steps of: placing a first and second bead around the tire carcass on the drum so that the carcass ends of the tire carcass extend laterally outward of the beads; radially expanding the first and second bead locks into engagement with the first and second bead; and expanding the carcass located between the bead locks radially outward by radially expanding a center section of the tire building drum while moving only the bead lock on the outboard section axially inward towards the inboard section.

摘要： A tire building drum and a method of building a tire carcass is disclosed. The tire building drum has a center section comprised of a plurality of segments that are radially and axially movable. The sleeve of the tire building drum over the center section has been eliminated, and instead has two seals located on the outer ends or shoulders of the center section of the tire building drum. The building drum further comprises shoulder sections that are axially movable. The shoulder sections include radially expandable bead locks. The method employs the steps of applying one or more carcass layers, locking the bead locks and moving the center section radially outwardly while moving the bead locks axially inwardly.

摘要： Auxiliary support members are brought into engagement with a building drum provided with a first outer circumferential surface. These auxiliary support members each have a second outer circumferential surface which extends in the continuation of the first outer circumferential surface. A separation element having a circumferential support surface is provided at a radially external position on each of the auxiliary support members. A component of the tyre is applied around each of the circumferential support surfaces and the auxiliary support members are subsequently axially moved away from the building drum, so as to radially contract the circumferential support surfaces to decouple them from the respective components of the tyre.

摘要： Tire building drum and tire building method, capable of assembling tire component members with high accuracy. A tire building drum is used, which includes at least one core body, which is disposed at an axial inside of a pair of bead lock means, and which comprises a plurality of sheets of rigid support members disposed in a toroidal shape and adapted to be displaced and thereby expanded or contracted. Bead cores are locked by the bead lock means, respectively, and a center portion of a carcass band is bulged while displacing the bead lock means close to each other. Back side portions of the carcass band are folded to radial outsides around the bead cores, respectively. The core body is then radially expanded to the maximum diameter while locking the bead cores, and tire component members are assembled onto the radially expanded core body.
