    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: 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 green tyre (2) for bicycles is built, comprising at least one carcass ply (4) having axially opposite end flaps (4a) engaged with respective bead cores (5) and a tread band (6) applied in a radially outer position around said at least one carcass ply (4). The built tyre (2) removed from the building drum, is profiled so as to translate the tread band (6) in a radially outer direction with respect to the bead cores (5), so as to impart a cross-sectional convex profile to the tyre (2) in a radially outer direction. The profiled tyre is engaged by means of a transfer member (31) comprising a gripping device (30) which retains it at the radially outer surface (2b) so as to maintain said cross-sectional convex profile in a radially outer direction.

    摘要: An application device for applying a conductive insert on a tyre being processed. The application device includes a supply device for supplying a conductive liquid elastomeric compound, and an applicator having a movable surface for being operatively coupled with the supply device and receiving the conductive liquid elastomeric compound. The movable surface is for being placed in contact with a rotating tyre being processed and for applying the conductive liquid elastomeric compound on at least one coil of axially adjacent and/or partially superimposed coils. The applicator generates depressions in the tyre in a pattern defined by elements in relief and fills the depressions in the tyre with the conductive liquid elastomeric compound to covering the elements as the depressions in the tyre are generated.

    摘要: A tyre for vehicle wheels comprises a carcass structure including at least one carcass ply having a plurality of hybrid reinforcing cords (10). Each hybrid reinforcing cord (10) comprises at least two strands (20a, 20b) twisted together with a predetermined twisting pitch (P). Each of said at least two strands (20a, 20b) comprises at least one monofilament textile wire made of polyester fibres and at least one multifilament textile yarn (22a, 22b) comprising a plurality of textile filaments (23a, 23b) made of aramid and/or polyester and/or rayon fibres. In any cross section of the hybrid reinforcing cord (10), said at least one monofilament textile wire is at least partially embedded in the filaments (23a, 23b) of said at least one multifilament textile yarn (22a, 22b).
