Abstract:

A control system for operating a vacuum forming machine in a program mode and in an automatic mode. A plurality of switches movable to control and clear positions are employed to set up a sequence of steps for operating the machine in the program mode. The sequence of switch positions is stored in a memory system during the program mode and read out during the automatic mode to allow the machine to carry out and duplicate the sequence of steps in the same time relationship as occured during the program mode.
