ABSTRACT:
In a device for transversely welding and cutting tubular film into bags, feed rolls advance the film to a gripping rail which grips the leading end of the film during operation of cutting and welding devices located behind the gripping rail in the direction of feed. To ensure proper tensioning of the film, the feed rollers are reversed after the film is gripped and prior to operation of the cutting and welding devices.
