| 摘要 |
The invention relates to a method and device for the production of tubular films (200a, 200b), for application to an object, comprising at least one pre-folding station (20), for folding up both lateral regions (16a, 16b) of the film web (12), each along a folding edge (K12a, K12b), stretching along the running direction of the film web, at least one flat folding station (30), for the essentially symmetrical pressing of both folded lateral regions (16a, 16b) onto the central region (18) of the film web (12) and at least one welding station (60) for forming the tubular film by welding each lateral region (18), in particular in the vicinity of each lateral edge and the section of the central region spatially close to each lateral region. |
