    摘要: Method and apparatus for welding two container walls of plastic film (1, 2) to a plastic tube (3) having a substantially circular cross section, wherein the plastic tube (3) is arranged between two parallelly arranged plastic films (1, 2). The two plastic films (1, 2) are made to extend along the outer surface of the plastic tube (3) and to abut each other along a joint face (7) between two welding jaws (5, 6) in an area (8) adjoining the plastic tube (3). The plastic films (1, 2) are welded by means of welding jaws (5, 6) to the outer face of the plastic tube (3) and welded together in the area (8) adjoining the plastic tube (3). The plastic tube (3) is deformed during weld­ing by means of a compressive force applied by the welding jaws (5, (5) to provide the outer surface of the plastic tube (3) with a substantially plane portion (9) extending on both sides of the joint face (7) and substantially perpendicular thereto.
