Abstract
The folding-up system is intended to fold an end portion of a cylindrical wall of a tire carcass assembly around a reinforcing bead core. The system comprises a drive device that is arranged to cause the carcass assembly to revolve intermittently about its roll axis, by successive angular increments, together with a folding device to cause pressure rollers to tilt. After each angular increment in roll, about a pitch axis perpendicular to the roll axis, in order to fold each portion of the end section located in an angular working sector occupied by a pressure roller towards the radially inner face of the wall, around the reinforcing bead core. Finally, the drive device includes a selector for placing the pressure rollers in a withdrawn position to disengage the trajectory followed by the wall of the carcass assembly during its roll rotation.
