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： A method for verifying the correct formation of the beads in a process and a plant for building tyres for vehicle wheels, includes: loading a plurality of annular anchoring structures in a storage, disposing them in two groups separated by an opening; positioning a building drum provided with a carcass sleeve in a tyre bead-forming machine; picking up two of the annular anchoring structures from the storage and loading them on the tyre bead-forming machine. In a work area of the tyre bead-forming machine, on each of two axially opposite zones of the carcass sleeve, a respective annular anchoring structure is fit and each of the abovementioned zones is turned up around the respective annular anchoring structure to form the beads. The aforesaid opening allows an operator to conduct a visual inspection of the work area and/or access the work area during the entire work cycle of the machine.

摘要： A process and an apparatus for building tyres for vehicle wheels includes assembling at least one tyre component through laying of strip-like elements disposed circumferentially close to each other on a deposition surface radially external to the forming drum, wherein laying of each strip-like element includes: radially moving the strip-like element close to the deposition surface; locking a central portion of the strip-like element against the deposition surface; and pulling the strip-like element in opposite directions starting from the central portion toward the opposite ends thereof, while the central portion is maintained in a locked condition against the deposition surface, so as to progressively lay down the strip-like element against the deposition surface.

摘要： In an assembly station, a carcass sleeve and an outer sleeve manufactured along respective building lines are mutually coupled. Integrated into the assembly station are engagement devices that can be alternatively-coupled to an auxiliary drum carrying an outer sleeve and to a building drum carrying a carcass sleeve. The building drum is engaged on the assembly station before removal of the auxiliary drum. A grip unit picks up the outer sleeve from the auxiliary drum associated with the engagement devices in order to position it around the carcass sleeve carried by the building drum.
