| 摘要 |
The invention concerns an apparatus for welding the tubular sections of sacks, bags or the like, having a rotating drum and with welding stations arranged on the periphery of the drum which rotate, fixed in position, with the drum, wherein the welding stations are arranged laterally each on one end side of the drum. To ensure a crease-free processing of the tubular sections to be welded, grippers that can be caused to open and close are arranged on the drum in individual welding stations, for the seizing, holding and release of the tubular sections. A movable welding jaw of the welding station forms a flat bearing surface for the zone of the tubular section to be welded, while the drum itself, has a cylindrical peripheral surface. |
