Abstract
Systems and methods utilizing stationary and/or moveable cutting components provide limited interference with web processing operations, such as pad spin and pitch alteration. Heat, laser, fluid, or mechanical cutting operations may be used, including respectively, a heated element (e.g., wire, ribbon, bar, or embossing or perforating element) that may be triggered inductively, water or steam jets, or improved knife/anvil cooperation.
