Abstract

The invention relates to a stripper mechanism for a tubular bag packaging machine, in which a foil strip (1) is formed into a tube (3) by means of a longitudinal sealing jaw (2) and is formed into bags by means of cross-sealing jaws (4). A stripper mechanism (5) is arranged in the area of the cross-sealing jaws (4), which stripper mechanism (5) includes two stripper rods (6) supported on the end areas of support arms (7). In order to provide a drive for the stripper mechanism (5), which drive is independent of the drive of the cross-sealing jaws (4), the stripper rods (6) are connected to a common closing mechanism (8), and that furthermore the stripper rods are connected to a moving mechanism (9) for effecting a relative movement along the foil tube (3).
