ABSTRACT OF THE DISCLOSURE An input shaft of a press feed is rotated at a preselected speed and is drivingly connected to a cam that rotates with the input shafts. Continuous rotation of the cam is converted to oscillating rotational movement of a cam follower through a preselected angle of rotation; The cam follower is nonrotatably connected to an output shaft that is connected by an adjustable linkage mechanism through a pair of meshing gears to a driven feed roll. The oscillating rotational movement of the output shaft is transmitted to the driven feed roll to advance the driven feed roll in contact with stock material through a preselected degree of rotation corresponding to a preselected feed length of the stock material to the press. A clamp is provided for intermittently engaging the workpiece to prevent movement thereof. The clamp is also cam driven through an air-actuated clamp cylinder.
