ABSTRACT:
Apparatus for feeding, locating and ejecting tubular workpieces to and from a horizontal recess in a vertical die face wherein the workpiece projects beyond the opposite sides of the die includes a horizontally reciprocable feed means mounted for reciprocatory movement between a forward and rearward movement relative to the fixed die. The feed means includes a horizontal pusher plate which upon movement from its rearward end to its forward end limit pushes a horizontally disposed workpiece forwardly across the top of the die and over the front edge of the die. Horizontal locator bars stop the falling workpiece in front of the recess and fingers carried on spaced side plates of the feed means guide the workpiece downwardly along the die face. Upon rearward movement of the feed means from its forward end limit, the fingers pivot against biassing means to ride upwardly over the workpiece which at this time is clamped in the recess by a movable die.
