Title: PROCESS AND APPARATUS FOR HANDLING GREEN TYRES FOR BICYCLES
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 green 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) while the tyre itself is mechanically restrained so as to maintain at least partly said cross-sectional convex profile in the radially outer direction.
