    Patent number: 4535617
    Abstract: A stamping machine composed of a frame supporting a movable carriage having thereon a reciprocal operative punch and die for punching holes in material controllably fed to the die. The carriage movement is controlled by an eccentric mechanism within the confines of two barrier walls which limit the traverse of the carriage. The material is held firm by a clamp during the punching process and released for movement to permit the punch to pull the material a distance equal to the pitch of the stamping cycle, to await the next cycle of stamping.
