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. When a packing is at a nip with an anvil roller, the infeed web is drawn in a downstream direction. When a circumferential space is at the nip, the infeed web halts downstream motion. When a knife blade is at the nip, the knife blade sheets the infeed web. An insert station cooperates with the cutting die to longitudinally space the articles as they merge to and are propelled downstream by the carrier web. At a subsequent station, the composite web is cut to manufacture individual products.
