ABSTRACT:
The invention relates to a device and method for expanding bags and slipping them on to a filling neck, especially bags with side folds, which are fed individually on to an aligning table, with the bag opening being positioned at the front, there being provided at least first suction means which are supported at the aligning table and which, in the region of the bag opening, are movable against the lower bag wall; at least second suction means which are supported at the aligning table and which are movable against the upper bag wall, the two sets of suction means being removable from one another while being vacuum-loaded; a pair of expanding blades which are movable into the seams of the side folds, which are secured to first pivot elements and are pivotable around a horizontal pivot axis positioned above the aligning table; a pair of bag grips with pairs of claws which are pivotable around rotational axes positioned parallel to the plane of the aligning table and, in consequence, may be opened and closed and are arranged in such a way that they each grip the two side folds in the region of the bag opening; as well as pivot elements for the bag grips which are pivotable around the same horizontal axis positioned above the aligning table as that of the first pivot elements for the expanding blades.
