ABSTRACT:
A device for producing tubular bags filled with bulk goods from continuous foil tubes. The device includes a pair of sealing tools that seal or weld the foil tubes in bag-length intervals. A pair of closing bars connected to the sealing tools are biased toward each other and press the foil tubes before the sealing tools are closed. A stripper is provided to remove the residue of the bulk goods from the area of the seal by a wiping motion in the direction of bag movement through the device. The closing bars are connected to the stripper so that through a closing movement of the closing bars, the stripper is pulled along in the run direction of the foil while touching the foil to strip the area to be sealed before the sealing tools close.
