Abstract: A slip cutting system sheets an infeed web into discrete articles and merges the articles to a carrier web. The slip cutting system comprises a continuously rotating cutting die having knife blades and packings consecutively around a peripheral surface. The packings cooperate with the knife blades to define a circumferential space between each packing and an associated knife blade.
