发明名称 APPARATUS FOR EVACUATING AND CLOSING BAG PACKAGE
摘要 A bag evacuating and closing apparatus having two opposing jaws which face ends that move toward one another. The jaws encompass a top closure of a bag package to be sealed. The jaws have hollow spaces open toward one another which are surrounded by frames with sealing jaws disposed in the hollow spaces; the hollow spaces form a chamber that receives the top closure of the bag package. A sealing rib protrudes from one face end of the two frames and is interrupted in a middle region of the frame part at which the closure fold protrudes between the jaws. In this region, suction openings are disposed in the frame parts of both jaws; these suction openings pull two walls of the top closure tightly against the frame parts. After the top closure of the bag package has been tightly encompassed, air is extracted from the bag package by a vacuum, and subsequently, the top closure of the package is tightly sealed by the sealing jaws which form a sealing seam to close the upper end of the bag.
