摘要：
To obtain a device for welding plastic films which is light, compact and easy to operate, the two pressure rollers (40, 47) are driven by a single motor (19) arranged inside the transverse part (4) of a U-shaped housing (1) or inside a tubular pressure element (135) of a pressure mechanism (136), which runs parallel to and at a distance from the transverse part (103). The welding device is particularly suitable for welding operations carried out in a vertical plane or overhead, for example when lining tunnels.
