摘要： A process for manufacturing tyres for vehicle wheels, comprising the step of building on a forming support a carcass structure comprising at least one carcass ply and, at at least one end edge of the carcass ply, at least one annular anchoring structure comprising at least one substantially circumferential annular insert and at least one filling insert associated to said at least one substantially circumferential annular insert. The step of building the carcass structure comprises the steps of positioning the annular anchoring structure on the carcass ply by moving the annular substantially circumferential insert into contact with an end edge of the carcass ply by means of a special positioning member, pulling down the filling insert on the end edge of the carcass ply and turning up a free end portion of the end edge of the carcass ply so as to form a turned up end portion of the carcass ply including said annular anchoring structure. The pulling down of the filling insert on the end edge of the carcass ply is carried out by a special pulling down member while the substantially circumferential annular insert is retained into a contact position with the end edge of the carcass ply by said positioning member.

摘要： A rotatable tire building drum 10 has a pair of axially and radially moveable bead locks 20 and a radially expandable center building deck assembly 40 with two sets of deck plates when expanded forms a 360 degree solid deck surface. The deck plates have been sized to abut when fully expanded to form a solid 360 degree building surface to support a tire carcass 2. The two sets of deck plates are divided into a first set of even deck plates and a second set of odd deck plates, arranged in a sequence of at least 6 or more circumferentially adjacent abutting deck plates 1, 2, 3, 4, 5, 6 in an expanded state. In a retracted state, the first set of even deck plates 42 moves radially inward of the second set of odd deck plates 44, the first set 42 underlying the second set 44.

摘要： Apparatus and methods of forming a tire. A drum has an expansion device that is configured to turn-up the lateral ends of the tire carcass about respective bead-and-apex assemblies while generally maintaining a constant orientation of the bead-and-apex assemblies. Further, the expansion device turns-up the lateral ends of the tire carcass while at the same time radially expanding the tire carcass. The methods entail turning-up the lateral ends of the tire carcass around the bead-and-apex assemblies and also moving a portion of the tire carcass lying between the bead-and-apex assemblies in a radially-outward direction relative to an axis of rotation of the drum.

摘要： The invention relates to a device for turning up a tyre-building part on a tyre-building drum using a roller lever. In order to produce a device for turning up a tyre-building part on a tyre-building drum, by means of which the tyre-building part is turned up without defects, in particular an unintended crease formation in the lateral wall, according to the invention the roller lever (5) comprises a lifting roller (7) on the side thereof directed towards the drum axis (3) of the tyre-building drum (2), opposite which a ramp-shaped component (12) is arranged. As the tyre-building part (1) is turned up, the roller lever (5) is raised by means of the lifting roller (7) to a pre-position, wherein, as the roller lever (5) is lifted to the pre-position, the crimping roller (6) is spaced in such a way that the crimping roller (6) is substantially exclusively in contact with the tyre-building part (1) and the roller rolls along the tyre-building part (6).

摘要： By increasing the number of segments constituting the outer periphery of a tire building drum, sufficient roundness is ensured for the tire building drum in a wide diameter expansion/reduction range. The tire building drum used for manufacture of an unvulcanized tire is expanded or reduced in diameter in at least a part of the outer periphery by displacing a plurality of extensible/contractible segments sequentially arranged in the drum peripheral direction. Furthermore, the tire building drum is provided with a pair of segment displacing means which expand/contract the plurality of segments, and the pair of segment displacing means are alternately connected to each of the segments in the drum peripheral direction. Each of the connected segments is displaced, respectively, by the pair of segment displacing means.
