| 摘要 |
The present invention relates to an apparatus (40) for facilitating reforming of a web (10) of flexible packaging material into a tube (19), the web (10) including a crease pattern which has crease lines (11) running substantially transversely of the web, and the web (10) running over a deflector device (18) before the reforming into the tube is initiated. The apparatus (40) is characterised in that it includes a form device (42) which is disposed downstream of the deflector device (18) but upstream of tube forming means (20), the form device (42) at least in one case where a sprain has been formed in the web along one of said transverse crease lines, being disposed to be in contact with one side (17) of the web (10) which is intended to form an inside of the finished tube, so that the web (10) is given an indication to commence the reforming into the tube. The invention also relates to a method for facilitating reforming of a web (10) of flexible packaging material into a tube (19). |
