ABSTRACT:
A method and apparatus for making plastic articles utilizing a plurality of tools, each of which is moved by cams and includes a nitrogen cylinder wherein provision is made for catastrophic overload prevention. For catastrophic overload prevention, one of the cams is supplied by a top plate and held in normal fixed position by a plurality of nitrogen cylinders. Abnormal movement of the top plate is detected and the machine is stopped. For predictive overload protection, a load cell is positioned at the off load position of one of the cams and any excessive load provides a signal for an alarm, interrupting the feeding of plastic charges and stopping the machine.
