Abstract:
A toroidal carcass is formed using a toroidal frame defined by two annular beads and by a removable outer ring divided into angular sectors; a winding device for feeding a spool, housing a cord, about and through the frame from a first to a last of the angular sectors; and an actuating device, which, before the cord is wound completely, moves the first angular sector into an operating position defining, with the last angular sector, an opening for the passage of the spool.
