ABSTRACT:
This invention relates to a gripping feeder for an intermittent feeding of strip or wire stock in presses, stamping machines or similar machines. It is an object of the invention to provide such gripping feeder which permits a change of the stroke length to be effected from the outside while the machine is in operation and permits such change to be effected manually or by means of an adjusting motor and also permits an automatic adaptation of the feeding and retaining grippers to the thickness of the strip or wire stock to be fed. This is accomplished in that the carriage carrying the feeding gripper is adapted to be driven from the main drive of the machine via a feed rocker, which extends transversely to the direction of travel of the carriage and is fulcrumed on a slider, which is slidable along a rail that extends transversely to the direction of travel of the carriage so that an adjustment of the slider along said rail will result in a change of the stroke length of the carriage. The feed rocker fulcrumed on the slider is preferably adapted to have an oscillating angular motion about its fulcrum imparted to it by a pivoted finger, to which an angular oscillation is imparted from the main drive, and which is pivoted to one arm of the feed rocker, the other arm of which is connected to the carriage by a link for imparting a reciprocating linear movement to the carriage.
