Abstract
The invention relates to a method for vacuum-packaging bags filled with articles and to an apparatus therefor. Such packaging bag is stored in a chamber and a vacuum is applied to the interior of the chamber; the opening edge of the packaging bag is sealed. Such chambers are suspendedly supported on a rotor rotating around a horizontal axis. The chambers are rotated with the rotor along a circular path in a vertical plane. At this time, the component force acting on a packaging bag is smaller than in the case where the chambers are rotated along a circular path in a horizontal plane. As a result, deviation of packaging bags is prevented.
