Abstract: A method of separating strands of a slit web is disclosed. The method includes providing a slit web having a length in a machine direction and running the slit web in the machine direction onto a stretchable surface. The slit web includes multiple strands provided by a plurality of slits extending in a first direction not parallel to a cross-machine direction. The slit web 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 slit web and the stretchable surface during the stretching at least partially separates at least some of the multiple strands of the slit web in a second direction transverse to the first direction. A method of increasing a width of a polymeric netting is also disclosed.

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.
