Abstract: A rotary cutting apparatus including a frame, a die roll rotatably attached to the frame including a cutting member, wherein the cutting member includes at least one tensioning device and the tensioning device includes a body and a tip portion adjacent to the body, the tensioning device having an unsymmetrical profile.

Abstract: An anvil for a rotary cutting unit includes a shaft having an outside surface and at least one cladded layer applied to at least one portion of the outside surface of the shaft. A method of producing the anvil includes the steps of applying a wear resistant powder material to at least one portion of the outer surface and heating the wear resistant powder material with, for example a laser, to melt the powder and to fuse it into at least one layer on the shaft.
