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 reinforcement annular structure (7a) of a tyre (2) being processed is formed by means of the actions of: arranging a forming drum (19) externally carrying a deposition surface ("S1"); arranging an application member (46) supported in thrust relation towards the deposition surface ("S1"); longitudinally guiding a continuous elongated element (34) towards a point of application ("P") between the deposition surface ("S1") and a work surface (48) presented by the application member (46); winding the continuous elongated element (34) circumferentially around the deposition surface ("S1") in order to form coils ("C") that are axially side-by-side each other. During winding, the work surface (48) of the application member (46) operates in abutment relation against at least one of the coils ("C") previously formed by the continuous elongated element (34).

摘要： The invention is related to a process and an apparatus for building tyres and to a tyre for vehicle wheels. It is provided to form a substantially cylindrical carcass sleeve (24), comprising at least one carcass ply (3), formed by laying consecutively adjacent strip-like elements (29) one after the other around the circumferential extension of a substantially cylindrical deposition surface (10a). Circumferentially consecutive strip-like elements (29) are laid one after the other to form overlap zones (30) along respective longitudinal edges (29a, 29b) superimposed on each other. Each overlap zone (30) has, along a longitudinal extension thereof, terminal sections (32) that are laterally opposite with respect to an intermediate section (31). The intermediate section (31) of each overlap zone (30) has greater width than the width of the terminal sections (32).
