A process for manufacturing a tyre for vehicle wheels, comprises the step of building, on a forming support (50) extending about an axis (X-X) r a carcass structure comprising at least one carcass ply (2) and, at at least one end edge (2a) of said at least one carcass ply (2), at least one annular anchoring structure (10). The step of building the carcass structure comprise steps of laying the carcass ply (2) on the forming support (50), bringing the annular anchoring structure (10) in contact position with the end edge (2a) of the carcass ply (2) and turning up the end edge (2a) about the annular anchoring structure (10) so as to form a turned up end portion of the carcass ply (2) including the annular anchoring structure (10). A first part of the step of turning up the end edge (2a) of the carcass ply (2) is carried out while at least one positioning device (110) retains the annular anchoring structure (10) in contact position with the end edge (2a) of the carcass ply (2). |
