Method of and apparatus for controlling a bag forming, filling and sealing machine by monitoring the machine cycle and controlling the jaw closure mechanism based on a previously determined jaw closed point. If the jaw closed indication is received prior to the previous value plus offset, the sealing cycle continues normally and all functions interlocked to jaw closed position such as knife, impulse, etc. are allowed to function normally. If the jaw closed signal is not received prior to the previous value plus offset the jaw close function is inhibited signifying a jam condition and the interlocked functions such as knife, impulse, etc. are inhibited. This function is independent of any external adjustment and serves as a safety device in all modes. |
