Summary: | An apparatus for building tyres, a holding device (8) comprises a fixed body (10), a rotatable body (11) and a motor (12) coupled to the rotatable body (11) to drive it in rotation. The rotatable body (11) comprises a first element (13) provided with a housing axial seat (14) configured for receiving the rotating shaft (4) of a forming drum (2) and a second element (15) provided with at least one holding member (15a) for holding rotating shaft (4) elastically moveable between a first axial position and a second axial position. An actuator (19) operates between the first element (13) and the second element (15) to displace the second element (15) from the first axial position to the second axial position. An anti-rotation unit (21) is selectively displaceable between an active condition, in which it rotatably constrains together the rotating shaft (4) and the first element (13) of the rotatable body (11), and a passive condition, in which it does not interfere with the rotating shaft (4) of the forming drum (2). |
