Abstract

The vacuum packing machine has a vacuum chamber in a housing and which is sealed by a cover. A mechanism (9, 10) pulls back the end (6) of a bag placed in the chamber (2). A groove (9) is formed in the housing edge (7), in which an oblong component (10) fixed to the cover (3) is inserted. This automatically pulls the protruding bag end into the groove on shutting the cover. The oblong component can be a bar mounted clear of the cover base (12) and pressed into the cover against spring action, working on a guide bolt (11) fixed to the cover base, and round which a spring (13) fits.
