Abstract: The invention relates to a folding blade for a blown film line, as well as to a blown film line equipped therewith. Folding blades are used for laterally folding in a film bubble running to the take-off pinch rolls. If they engage deeply into the film bubble, they are provided with a fin on the rear side, and referred to as deep folding blades. The invention proposes that the rear side of a folding blade be equipped with a fin, which exhibits a collapsible element with an adjustment device. The volume of the fin can thereby be varied. In particular, the fin can be laid flat against the rear side of the folding blade.

Abstract: The apparatus for handling a finished roll and a winding shaft on a winding apparatus for webs of material is configured with spaced apart rails pivotal independently from one another between a winding station and a setting-down station. Each of the rails supports a carriage operative to support the winding shaft and release it upon pivoting the rails towards the setting-down station, where at least one of rails pivots away from the winding shaft so as to facilitate removal of the roll from the shaft.
