ABSTRACT:
In a gusset-shaped space 6 between a film roll 8 and a contact roller 3, two air displacement rollers 5a,5b, are arranged parallel to the axes of the film roll and the contact roller. These rollers have in contrast to the contact roller and the winding core 2, and the film roll, respectively, small diameters of 7.5 to 50 mm. These rollers displace the air layers 4 adjacent to the film web 1 which are moving into the gusset. The selected distance for the displacement of the air layers between the point of contact of the film roll and the contact roller is so small, that new air layers on the film webs within the gusset can only be formed in the smallest amounts.
