Abstract: PURPOSE:To prevent the occurrence of wrinkles near the tabs of a bag by providing a pair of bag stretching pawls adapted to be lowered into the bag to pull near the upper part of the bag opening after the bag setting and tab gripping parts for gripping the tabs at both the sides of the bag mouth from the start of bag stretching by the bag stretching pawls to the end of heat sealing. CONSTITUTION:A bag 26 having its mouth opened by a bag feeding mechanism is set directly below a filling nozzle mechanism 10 and a pair of bag stretching pawls 21A and 21B are lowered into the mouth of the bag 26 and moved in opposite directions to force apart the bag mouth from inside. At this time, a pair of tab gripping parts 24A and 24B, each being located outside a corresponding one of the bag stretching pawls 21A and 21B, grip the tabs on both the side of the bag mouth and move in the bag mouth stretching direction to pull the tabs in exactly horizontal and opposite directions. This prevents the tab displacement and consequent occurrence of wrinkles near the tabs. Therefore, this sealing device is usable in vacuum pack application and there is no need for a separate temporary pressing body, resulting in a simplified structure.
