ABSTRACT:
The present invention concerns a tire-building process in which a so-called "shaping" building drum is used and in which a ply turn-up bladder (2) is clamped on the outside of each bead recess (6) by an assembly of pallets (11) which can open in fan shape and cover the turn-up bladder completely in circumferential direction and in part in axial direction. The axial displacement of the said pallets (11), controlled by the axial displacements of two pistons (7) and (8), makes it possible to modify the shape of the ply turn-up bladder (2).
