Abstract
The track for a pressure chamber overlaps the track for a clamper in movement while clamping a bag filled with an article, at a position beneath the latter track and with a level difference. The bag supported by the clamper is held, at its upper edge positioned right below the clamper, between the upper side of a chamber body of the pressure chamber and the upper side of a cover and in a sealed condition. The air in the bag is expelled through a notched line formed in an upper portion of the bag as the pressure within the pressure chamber is reduced, and then the bag is sealed at a position below the notched line.
