A web tensioner, a web slitter, a method of tensioning a web, and a method of slitting a web are provided. A corrugated edge nip is used in the tensioner, the slitter, and the methods of tensioning and slitting. The corrugated edge nip can provide a crossweb tension to a suspended web or film in a web line. The corrugated edge nip can be used in conjunction with, for example, a rotary shear slitter to improve slit edge quality.
