GUIDE ASSEMBLY FOR CONTROLLING THE FEEDING OF STOCK MATERIAL

摘要

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 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 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 material guide assembly provides a preselected spacing so that the feed of stock material of a preselected thickness is maintained along a substantially linear path. The guide assembly has a movable guide spaced from a stationary guide with the stock material fed between them.
