Abstract
A packaging machine for manufacturing filling and closing of bags. A foil tube (4) is pulled off continuously by means of unwinding belts (13) on a packaging machine contracted as a tubular bag-forming machine. Cross sealing seams are created by means of continuously moving cross sealing jaws. The cross sealing jaws are maintained in a horizontal position during their entire movement by being guided in guide grooves. The guide curves have straight curve pieces in the area of a sealing zone, which curve pieces extend parallel with respect to the unwinding direction of the foil tube (4). The packaging machine permits a high operating speed, since the cross sealing occurs simultaneously with the unwinding movement and the cross sealing jaws, are guided exactly in an optimum position with respect to the foil tube. (4). The machine can be operated such that the unwinding speed for the thin sheet material is only a little slower than the speed of the goods to be packaged at the end of the fill pipe.
