MONITORING THE CLOSING ACTION OF A MOULD OF A GLASSWARE FORMING MACHINE

摘要

In the closing action of the mould, pulses are produced which represent the movement of a mould portion in the closing action. The number of pulses produced between a fixed position and the mould closed position is counted and compared with the greatest number of pulses previously counted for the corresponding movement. If the two numbers differ by a predetermined number, a stop signal is produced which presents further closing actions of the mould.
