Method and apparatus for fabricating stretch film rolls
An apparatus for fabricating a stretch film roll includes a device configured to fold a stretch film web to yield a folded stretch film web comprising at least one longitudinal band of increased thickness, with each band of increased thickness being spaced from the longitudinal edges of the folded stretch film web, and a driven winding shaft for winding the folded stretch film web.
Method and device for the production of a number of coiled foil rolls
The coiled foil rolls are reinforced in their edge region by folding. The coiled foil rolls are made by supplying a foil to coiling devices; cutting the foil in a conveying direction with a knife so that at least two foil sections are created which extend in a conveying direction; folding the edge regions of the foil sections by a folding device and laying the folded sections and the remaining part of the foil section on each other; and coiling the foil sections with the coiling devices. The knife or the folding device are moved simultaneous oscillating back and forth in a direction transversal to the conveying direction during the coiling of the foil sections.
