Abstract:
A method of increasing a width of a polymeric netting is disclosed. The method includes providing a polymeric netting having a length in a machine direction and running the polymeric netting in the machine direction onto a stretchable surface. The polymeric netting is in contact with the stretchable surface for a path length in the machine direction, and for at least a portion of the path length, the stretchable surface is stretching in the cross-machine direction. The traction between the polymeric netting and the stretchable surface during the stretching increases the width of at least a portion of the polymeric netting in the cross-machine direction.
