Abstract: 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.

Abstract: 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.
