Apparatus for perforating a nonlinear line of weakness
Last updated:
Abstract:
A perforating apparatus has a base having at least one counter component. The counter component has a length, L.sub.CC, and a nonlinear shape having a shape width, W. A support is operatively engaged with the base. A blade having a length, L.sub.B, is disposed on the support so as to cooperate in interacting relationship with the counter component. The blade has a plurality of teeth. A web material is perforated as it passes between the base and the support and the blade cooperates with the counter component. A driving means is associated with one of the support and the base to reciprocally shift the one of the support or the base for a distance, D, in a shifting direction. The distance, D, is at least the translational distance that one tooth travels to cover the shape width, W.
