METHOD AND APPARATUS FOR FABRICATING STRETCH FILM ROLLS
An apparatus for fabricating stretch film rolls comprises a plurality of cutting blades for cutting a stretch film web into one or more stretch film web sections, the plurality of cutting blades being configured to be oscillated. The apparatus also comprises a driven winding shaft for winding the one or more stretch film web sections.
1 . An apparatus for fabricating stretch film rolls, comprising:
a plurality of cutting blades for cutting a stretch film web into one or more stretch film web sections, the plurality of cutting blades being configured to be oscillated; and
a driven winding shaft for winding the one or more stretch film web sections.
2 . The apparatus of claim 1 , wherein each stretch film web section has non-linear longitudinal edges.
3 . The apparatus of claim 1 , wherein each stretch film web section is wound onto a core supported by the winding shaft.
4 . The apparatus of claim 1 , wherein the plurality of cutting blades is configured to be oscillated along an axis that is generally orthogonal to a direction of travel of the stretch film web.
5 . The apparatus of claim 1 , wherein the plurality of cutting blades is configured to be oscillated over a fixed distance.
6 . The apparatus of claim 1 , wherein the plurality of cutting blades is configured to be oscillated over a variable distance.
7 . The apparatus of claim 1 , wherein the plurality of cutting blades is configured to be oscillated at a fixed frequency.
8 . The apparatus of claim 1 , wherein the plurality of cutting blades is configured to be oscillated at a variable frequency.
9 . The apparatus of claim 1 , further comprising a roller positioned adjacent the winding shaft, a wound surface of the one or more stretch film web sections being in contact with a surface of the roller.
10 . The apparatus of claim 9 , wherein the roller is configured as a driven roller.
