ABSTRACT:
A heat-sealing apparatus having a fixed upper clamping jaw which defines therein a continuously energized resistance-type heater. A lower clamping jaw is supported on the frame for pivoting movement about a substantially horizontal axis, so that the lower clamping jaw can be manually swung upwardly to engage the upper jaw and clamp the mouth of a filled preformed bag therebetween. The lower clamping jaw, when manually swung upwardly, activates a control arrangement which holds the lower jaw in its closed position for a predetermined time and at a substantially predetermined pressure, thereby permitting effective sealing of the bag mouth. The control arrangement automatically terminates the clamping engagement between the jaws, whereby the lower jaw automatically swings downwardly to permit release and removal of the sealed bag.
