ABSTRACT:
A wall has a fixed support plate and a die face. A transfer housing and an air cylinder have a cylindrical rod horizontally secured to the support plate. The housing and air cylinder are laterally reciprocable upon the rod. Fingers have lower free ends for receiving a workpiece to be cold forged and delivering the workpiece to a die. The fingers have an upper follower. The follower is vertically reciprocable to move the fingers between an expanded orientation for releasing the workpiece and a contracted orientation for retaining the workpiece.
