Abstract
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 tire is engaged by means of a transfer member (31) comprising a gripping device (30) which holds it hanging and loads it into a vulcanisation mould (101) by axially positioning an axial centreline plane (M) of the green tyre at an axial reference (51) arranged at a predetermined height along a reference axis (K) of a central body (103) of the vulcanisation mould (101).
