ABSTRACT:
A packaging machine for the working and processing of at least one length of foil has a chamber consisting essentially of an upper part (1) and a lower part (2). The chamber parts (1,2) are moveable relative to one another on guides (6) on both sides of the foil (24) by means of at least one cylinder-piston arrangement (3) which drives a toggle lever arrangement (4,5). The cylinder-piston arrangement (3) is arranged in the median plane (7) between the guides (6) and drives the toggle lever arrangement (4,5) in the same way under the ends (8) of the guides (6), the toggle lever arrangement (4,5) driving the lower part (2). The toggle lever arrangement (4,5) is operably connected to a liftable and lowerable yolk (11) such that during lifting movement of the lower part (2) the yolk (11) descends, and vice versa, and the yolk (11) is rigidly connected to the upper part (1).
