Abstract: A carcass ply (3) is built on a forming drum (11) by application of a plurality of strip-like elements (13), through the steps of : setting a width of these strip- like elements (13), setting a width of the overlapped part S between two adjacent strip-like elements (13), setting a fitting diameter of the forming drum (11) by calculating a corresponding extension of a radially external laying surface (14), calculating a whole number (n) of strip-like elements (13) to be applied. The whole number (n) of strip-like elements (13) is applied by rotating the forming drum (11) around a geometric rotation axis (X-X) thereof, and applying pairs of strip-like elements (13) by means of a first laying unit (18) and a second laying unit (19) located close to opposite portions of the forming drum (11) relative to the geometric rotation axis (X-X). When the calculated whole number (n) of strip-like elements (13) is an odd number, before at least one application step, the first laying unit (18) is shifted along an adjustment path (C-C) orthogonal to the geometric rotation axis (X-X) and substantially tangent to the radially external laying surface (14) of the forming drum (11).

Abstract: In a process for building tyres for vehicle wheels, at least one tread band (9) or other elastomeric component of a tyre (2) is made by applying at least one continuous elongated element (14) according to a plurality of turns (C) around a forming drum (15) rotating around a geometric rotation axis (X) thereof. The continuous elongated element (14) is made by the action of extruding a first material through an extrusion nozzle (16), to form an inner core (33) of said continuous elongated element (14) exiting from an outlet opening (18) of the extrusion nozzle (16). During the extrusion, a second material different from the first material is conveyed around the first material, at the extrusion nozzle (16) and upstream of the outlet opening (18), to form a coating layer (32) which entirely surrounds the inner core (33).

Abstract: A green pneumatic tyre (2) is built on a rigid toroidal support (10) externally having a forming surface (10a) of a conformation corresponding to the inner shape of the tyre (2). The green tyre (2) engaged on the expandable toroidal support (10) is introduced into a vulcanisation mould (29) and submitted to a vulcanisation cycle. During vulcanisation, axial moving apart of side portions (19) of the toroidal support (10) is caused so as to press the beads (5) and sidewalls (8) of the tyre (2) against the vulcanisation mould (29).

Abstract: After a support structure (12) has been circumferentially positioned around an annular component (11) of a tyre (2), gripping elements (16) carried by the support structure (12) and circumferentially distributed around a central axis (X) are radially approached to the annular component (11) bringing into contact therewith a plurality of feeler pins (22), slidably carried by each of said gripping elements (16). Once contact is made, the radially approaching of the gripping elements (16) to the annular component (11) continues by sliding the gripping elements themselves along the feeler pins (22). All the feeler pins (22) can therefore come into contact with the annular component (11), copying the shape of the outer surface. The feeler pins (22) are then locked with respect to the gripping elements (16) in order to allow the removal of a support drum (10) from the annular component (11) and support the latter in the absence of normal stresses.
