Method and apparatus for fabricating stretch film rolls

1. A stretch film roll, comprising:

a wound stretch film web section having longitudinal edges that are non-linear, the stretch film roll comprising:

a cylindrical central portion; and

tapered end portions,

wherein the non-linear longitudinal edges comprise:

a first longitudinal edge formed by a first cutting blade that is oscillated; and

a second longitudinal edge formed by a second cutting blade that is oscillated.

2. The stretch film roll of claim 1 , wherein the stretch film web section has a variable width.

3. The stretch film roll of claim 1 , wherein the stretch film web section has a constant width.

4. The stretch film roll of claim 1 , wherein the second cutting blade is oscillated independently of the first cutting blade.

5. The stretch film roll of claim 1 , wherein each of the cutting blades is oscillated along an axis that is generally orthogonal to a direction of travel of the stretch film web section during cutting.

6. The stretch film roll of claim 1 , wherein the first and second cutting blades are oscillated along the same axis.

7. The stretch film roll of claim 4 , wherein the first cutting blade is oscillated in an asymmetric manner relative to the second cutting blade.

8. The stretch film roll of claim 1 , wherein at least one of the first cutting blade and the second cutting blade is oscillated over a fixed distance.

9. The stretch film roll of claim 1 , wherein at least one of the first cutting blade and the second cutting blade is oscillated over a variable distance.

10. The stretch film roll of claim 1 , wherein at least one of the first cutting blade and the second cutting blade is oscillated at a fixed frequency.

11. The stretch film roll of claim 1 , wherein at least one of the first cutting blade and the second cutting blade is oscillated at a variable frequency.
