Beschreibung
Zusammenfassung:	The invention concerns a method and device for controlling sheet-welding machines, in particular machines for manufacturing bags made by welding continuous tubular or semi-tubular strips of thermoplastic material, the device having a pair of sheet-feed rollers (2) and a pair of welding bars (4, 5). In order to improve performance and to be able to adjust the device to adapt it to different materials and to permit different welding-bar positions, the device is driven by a reversing crank gear.
