Abstract
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.
Claims6
A method for fabricating a stretch film roll, comprising:
- providing a stretch film web;
- folding the stretch film web using a device to yield a folded stretch film web comprising at least one longitudinal band of increased thickness, each band of increased thickness being spaced from the longitudinal edges of the folded stretch film web;
- oscillating the folded stretch film web using at least one component configured to be oscillated;
- and
- winding the folded stretch film web,
- wherein the at least one component configured to be oscillated is one or more of:
- at least one roller, the device, at least one guide, and a winding shaft.
4 more elements
A method, comprising:
- providing a stretch film web;
- passing the stretch film web between a member and at least one guide, the member comprising at least one channel, the at least one guide cooperating with the at least one channel to yield a folded stretch film web comprising at least one longitudinal band of increased thickness;
- and
- oscillating the folded stretch film web using at least one component configured to be oscillated, wherein the at least one component configured to be oscillated is one or more of:
- at least one roller, the member, the at least one guide, at least one additional guide, and a winding shaft.
