ABSTRACT:
A device for sealing plastic material bags having opposed jaw members movable between open and closed positions with one of the jaw members provided with a heat source and the opposed jaw member provided with a resilient jaw surface. One of the jaw members is stationary, the other jaw member is movable and is attached adjacent one end of a lever member pivoted intermediate its ends, the other end being associated with an electro-magnet with switch means for actuating the electro-magnet, the switch being actuated by manual movement of the movable jaw towards the stationary jaw. Activation of the switch controls electronic circuitry including timing means to actuate the electro-magnet to forcibly close the jaws and maintain them in a closed condition until interruption of power to the electro-magnet by a timing circuit. The movable jaw is normally biased away from the stationary jaw. The heat means may be provided with two heat ranges, the timer circuitry with two timing circuits, and the resilient facing with interchangable faces whereby the device is readily adaptable to different bag styles.
