A system and method for creasing continuous web at predetermined locations. A continuous web material is biased in the first direction. The web is then pinched in a second direction. This pinching is accomplished by drawing a bend in the web into the pinching element, and, following the pinching, the web including a crease is driven out of the pinching element. This section of web containing a crease is then output from the system. A second pinching may also be performed subsequent to the first pinching. This second pinching would occur on the opposite face of the web at a further point along the web. This would result in a zig-zag pattern of creases.
