Abstract
An input shaft of a press feed is rotated at a preselected speed and is drivingly connected to a cam that rotates the input shaft. 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 drive link and gear arrangement to a driven feed roll. Oscillating rotational movement of the output shaft is transmitted to the driven feed roll to advance the driven feed roll in contact with the strip material through a preselected degree of rotation corresponding to a preselected feed length of the strip material to the press. The end of the drive link adjacent to the output shaft is movable relative to the output shaft. A universal adjusting device is connected to the drive link to move one end of the drive link relative to the end of the output shaft as the oscillating rotational movement of the output shaft is transmitted from the drive link to the driven feed roll. Moving the end of the drive link toward and away from the axis of rotation of the output shaft permits adjustments to be made in the feed length of the strip material. By making adjustments in the feed length while the feed roll is being driven, the press feeding operation continues without delay due to a change in the feed length.
