ABSTRACT:
A single rotationally driven cam plate having cam follower grooves in its opposite faces generates and coordinates the movements of all apparatus components necessary to the product molding apparatus. The advancing and retracting of mold halves is coordinated through the rotating cam plate and directly associated mechanisms with the cutting off of pieces of moldable stock and the carrying of such pieces to a position for charging the mold. In conjunction with these operations and in properly timed relationship, the stock is advanced to a new cutting position. Certain of the cam driven mechanisms also act in proper sequence to advance molded product encapsulating films through a film guidance means and to operate film clamping and severing devices in such a way that the encapsulating film is always severed midway between molded product units.
