As illustrated in FIG. 5, a stepped anvil roller 502 can be stepped down so as to touch the blades of rotary die 501 and cut through the primary or secondary web material to produce what is known as a through-cut. Alternatively, regular anvil roller 503 is offset from the cutting surface of the rotary die 501, thereby only cutting a portion of the material it contacts to produce what is known as a kiss-cut. Manufacturing processes use the kiss-cut to cut only a portion of a multi-layered material, e.g., cutting a primary web material but leaving an attached liner intact.
