    摘要: Process and an apparatus for applying noise-reducing elements to a tyre for vehicle wheels that has a radially inner surface with a service area and having a circumferential dimension. The process determines the position in circumferential direction of the service area on the radially inner surface of the tyre, determines the position in circumferential direction of a target area on the radially inner surface of the tyre based on the position in circumferential direction of the service area, and applies a noise-reducing element at the target area. The position in circumferential direction of the service area is determined by circumferentially inspecting the radially inner surface of the tyre starting from a reference position, detecting the angular position of the service area with respect to the reference position and determining the position in circumferential direction of the service area based on the angular position and on the circumferential dimension of the radially inner surface of the tyre.

    摘要: The present invention is relative to a method for building tyres for vehicle wheels and to a transfer device (16) of an apparatus for building tyres for vehicle wheels. The centring device (16) comprises: an annular support structure (18); gripping elements (19) arranged as a ring on the annular support structure (18) and having gripping surfaces (20) directed radially towards a longitudinal axis (Z-Z) of the transfer device (16); a measurement device (30) mounted on the annular support structure (18). The measurement device (30) is configured for detecting the centring between the transfer device (16) and a drum (12, 13) situated within the transfer device (16). The transfer device (16) is configured for picking up the tyre being processed (14, 15) from the drum (12, 13) on which the tyre being processed is arranged or for depositing a tyre being processed (14, 15) on the drum (12, 13).

    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: Apparatus for applying noise-reducing elements to a tyre for vehicle wheels that has a radially inner surface with a service area and a circumferential dimension. The apparatus determines the position in circumferential direction of the service area, determines the position in circumferential direction of a target area on the radially inner surface of the tyre based on the position in circumferential direction of the service area, and applies a noise-reducing element the target area. The position in circumferential direction of the service area is determined by circumferentially inspecting the radially inner surface of the tyre starting from a reference position, detecting the angular position of the service area with respect to the reference position and determining the position in circumferential direction of the service area based on the angular position and on the circumferential dimension of the radially inner surface of the tyre.
