Claim:
1. A method for producing a carcass ply for a vehicle tire comprising: winding a ply onto a drum, the ply containing reinforcements extending in planes that extend longitudinally with respect to the drum, the reinforcements being located around a centerline longitudinal axis of the drum, mounting at least one assembly member in a way such that it is able to move in relation to the drum, and such that is able to, while it travels over the ply in a direction parallel to ends of the ply which face each other, bring the ends of the ply which face each other together and assemble them together, wherein the assembling together of the ply ends is butt-jointing the ends, prior to the step of winding the ply onto the drum, extending a blade that is able to move in relation to the drum independently of the one or of each assembly member in a position such that, after winding the ply onto the drum and the blade, the blade extends between the drum and the ends without extending between the drum and the rest of the ply, and the state in which the blade extends between the drum and the ends is achieved by passing one of the ends of the ply over the blade and then into contact with the surface of the drum in such a way that the ply is wound onto the drum as the drum rotates, and using the rotation of the drum to bring the one end of the ply into contact with the blade so that the blade is inserted between the drum and the one end of the ply, causing the one end of the ply to rise on the blade.
