Abstract
Curvilinear or other complex perforation patterns for paper products, such as paper towels and bath tissue, can be produced using a differential speed perforation nip formed between a rotating pattern roll and a moving anvil surface. The relative speed between the perforation elements on the surface of the pattern roll and the anvil surface shears the web at the perforation points.
