The invention concerns a vacuum packaging machine having a sub-structure (1) and a cover (2). The machine further comprises a vacuum chamber (3) which is disposed in the vicinity of the union between the cover (2) and the sub-structure (1) and which comprises an upper part (4) and a lower part (5). The machine cover (2) comprises a base member (10) and at least one arm (11, 12), the arm being connected to the base member at one end. The chamber upper part (4) is mounted on the cover member (10) and the chamber lower part (5) is disposed in the sub-structure (1). The machine sub-structure (1) is provided with at least one guide roller (21) for the cover arm (11, 12), this guide roller engaging in the cover arm. The cover arm end remote from the cover base member (10) is connected to a drive device (20) by means of which the cover (2) can be moved. A device (55) for delivering a foil (51) into the interior of the vacuum chamber (3) is provided.
A vacuum-packaging machine comprising a substructure (1), a cover (2) that is movable in relation to said substructure, and a driving mechanism for moving said cover (2) in relation to the substructure (1), wherein the driving mechanism (20) is designed such that movement of the cover relative to the substructure has a rectilinear component and a swivelling component, wherein the driving mechanism (20) is designed such that said rectilinear and swivelling components of the cover's movement are sequential and partly overlap each other, with the result that the cover's movement in a first end-region of travel is rectilinear and movement in an opposing end-region of travel is swiveling.
