Abstract:
An apparatus and method for separating a web material are disclosed herein. The apparatus includes a bedroll and a chop off roll. The bedroll includes a bedroll blade and a bedroll web pin. The chop off roll includes a pin pad and a plurality of chop off roll blades. The bedroll web pin, and the bedroll blade, mesh with the pin pad and the chop off roll blades. The chop off roll blades are moved relative to the bedroll blade, stretching and separating the web material. The web pin perforates the web material and may completely or partially separate a portion of the web material. The web pin and the separated portion perforate the pin pad. The separated portion is stripped from the web pin as the pin passes out of the pin pad.
