Method for perforating a nonlinear line of weakness

A method for providing a nonlinear line of weakness on a web material, the method comprising the steps of:

• providing a blade comprising a nonlinear shape, wherein the nonlinear shape has a shape width (W);
• providing a counter component in operative relationship with the blade and comprising a plurality of teeth;
• rotating at least one of the blade and the counter component into interacting relationship with the other of the blade and the counter component;
• feeding a web between the counter component and the blade such that while in interacting relationship the blade cooperates with the counter component to perforate the web, wherein the web is moving in a machine direction;
• and
• reciprocally shifting one of the counter component and the blade for a distance (D) in a shifting direction.

• feeding a web between the toothed component and the shaped component such that while in interacting relationship the toothed component cooperates with the shaped component to perforate the web, wherein the web is moving in a first direction;
• reciprocally shifting the shaped component for a distance (D1) in a second direction;
• and
• reciprocally shifting the toothed component for a distance (D2), in a third direction.
