ABSTRACT:
An automatic joining apparatus for automatically joining an attachment start edge and an attachment finish edge of a carcass play cut into a length somewhat shorter than a circumferential length of a former drum and wound around the former drum, is disclosed. The apparatus comprises a pair of magnet-containing drive rollers movable in the axial direction of the former drum while being held in contact with the proximity of the attachment start edge of the carcass ply and the proximity of the attachment finish edge thereof to join the attachment start edge and the attachment finish edge together, and a pair of gathering rollers movable in the axial direction of the former drum behind the magnet-containing drive rollers while being held in contact with the proximity of the attachment start edge and the proximity of the attachment finish edge to join the attachment start edge and the attachment finish edge together.
