For live center drive, one end of the engaging member is disengaged from the engaging member, while the other end thereof is engaged with the face plate to rotate therewith. For a chucking operation, another face plate is secured to the spindle and is selectively engaged with the pulley, with the one end of the engaging member being disengaged from the engaging member.
