ABSTRACT:
A feed mechanism for feeding a workpiece from a first position to a second position comprises a drive member having a carriage mounted thereon, the assembly of drive member and carriage being reciprocable between the first and second positions. The carriage and the drive member are relatively movable, and the carriage carries a clamping assembly, jaws of which are opened and closed in accordance with such relative movement. The carriage can, however, be locked to the drive member by operation of a locking mechanism. The locking mechanism is rendered inoperative when the feed mechanism is in the first and second positions, so that relative movement between the carriage and the drive member can occur, thereby opening and closing the jaws of the clamp assembly.
