A tyre breaker comprising at least two breaker plies (4) is assembled on a carrier ring (10) which is movable between ply fitting stations (2,3). …<??>The ring is mounted on an arm (5) which swings the ring (10) through 90 DEG to each fitting station (2 or 3) where the ply (4) is supported on a table. Each end of the ply is then moved from the table on to the ring by means of grippers (16), and rollers (18) then traverse the ring (10) to ensure that the ply (4) is positioned accurately. The joints formed in successive plies are diametrically opposed to one another. |
