    摘要： A tire manufacturing device includes: a molding drum; a first moving portion in which the molding drum moves in order to mold an inner liner layer on the molding drum; a second moving portion in which the molding drum moves in order to mold a ply layer on the inner liner layer; a stitcher position where a carcass band is formed by performing pressing from above the ply layer laminated on the inner liner layer; and a transfer position where the carcass band is transferred from the molding drum to a transport device that transports the carcass band to a subsequent process, and the stitcher position and the transfer position are adjacent to each other.

    摘要： A machine vision system is directed toward a tire building drum in a tire building machine. The machine vision system produces a three dimensional image of a green rubber tread applied to the tire building drum. A center of the green rubber tread is identified in the three dimensional image by performing at least one convolution with at least one profile trace of the green rubber tread and a predefined tread profile. A difference is identified between the center of the green rubber tread and a center of the tire building drum. The difference is used as a tread position feedback error to position an application of a next green rubber tread onto the tire building drum from a tread conveyor.

    摘要： In a shaping station (13), a toroidal forming drum (23) is positioned within a carcass sleeve (12) comprising at least one carcass ply (3) associated with a pair of beads (6) in radially inner position. The carcass sleeve (12) is toroidally shaped by radial expansion of the forming drum (23). The forming drum (23) carrying the shaped carcass sleeve (12) is removed from the shaping station (13). Tyre components (7, 8, 9) are applied externally on the shaped carcass sleeve (12), carried by the forming drum (23). At the end of the shaping and during the application of the tyre components (7, 8, 9), axially inner sides of said beads (6) are arranged axially against respective circumferential axially outer portions (S1) of an abutment surface (S) carried by the expanded forming drum (23), having shape corresponding to an inner shape of the shaped carcass sleeve (12).

    摘要： A turn-up section for a tire building drum, includes a plurality of turn-up arms distributed circumferentially about a central axis and an arm support for supporting the turn-up arms with respect to a base, wherein the turn-up arms are rotatable with respect to the arm support from an arms-down position towards an arms-up position in response to the movement of the arm support in an arm drive direction. Each turn-up arm comprises a hinge pin for rotatably coupling the respective turn-up arm to the arm support. The arm support includes a hinge seat for removably receiving the hinge pin of the respective turn-up arm. The hinge pin is retained in the hinge seat by one or more biasing members. The hinge pin of the turn-up arm is removable from the hinge seat in a radial direction with respect to the central axis by counteracting the bias of the one or more biasing members.

    摘要： A process and a plant for producing tyres for vehicle wheels are described. Building of a crown structure of the tyre includes building a crossed belt structure on a substantially cylindrical first forming drum, transferring the crossed belt structure from the first forming drum to an annular holding member, positioning a second forming drum in a radially inner position with respect to the annular holding member, transferring the crossed belt structure from the annular holding member to the second forming drum by radially expanding the second forming drum until it is brought into contact with the crossed belt structure so as to toroidally shape the crossed belt structure, and depositing at least one zero degrees belt layer on the second forming drum in a radially outer position with respect to the toroidally-shaped crossed belt structure.

    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.
