Plate cam 2 rotates about fixed axis A. Swinging carrier 1 oscillates about fixed axis B and has roller 6 which rolls along the working surface of cam 2. Cylindrical blank a is fed by carrier 1 to spindle 3, where it is clamped in a collet chuck. After the blank is clamped, carrier 1 is returned to its initial position by spring 4. Member 5 turns about axis C of carrier 1 and supports the blank. Member 5 is held in contact with the blank by spring 7.
