Abstract: A method and an apparatus for manufacturing of articles from continuous film webs (2, 3, 5, 6) by means of welding the film during transportation of the film webs through treatment stations (24, 25, 26). The film webs are during their transport supported by a movable conveyor belt (40) and welded against the conveyor belt so that the film webs (2, 3, 5, 6) adhere to and are connected to the belt and conveyed via formed connections (45) and are released from the conveyor belt after accomplished transportation.
