Beschreibung
Zusammenfassung:	A method of perforating a web includes: rotating a cylinder comprising a longitudinal cylinder axis and at least one shaped anvil disposed on the cylinder; operatively engaging a support with the cylinder, wherein the support is moveable with respect to the cylinder; positioning a blade disposed on the support so as to cooperate in contacting relationship with the anvil, wherein the blade is substantially parallel to the longitudinal cylinder axis, and wherein at least one of the blade and the anvil comprise a plurality of teeth, and wherein adjacent teeth are separated by a recessed portion; and feeding a web between the cylinder and the support while the blade cooperates in contacting relationship with shaped anvil to perforate the web.
