Abstract

A knife is disclosed for cutting a plurality of articles from a sheet or web of material.
The knife can be formed or secured to the outer surface of a rotary die cutter. The knife includes a first cutting member having a first end; and second and third cutting members joined to the first end of the first cutting member. The second and third cutting members are arranged relative to one another to form an angle therebetween of from about 15°
to about 180°. Each of the second and third cutting members also has an arcuate section which intersects with the first cutting member to form a general wishbone configuration. This unique knife profile enables two adjacently arranged articles to be simultaneously cut from a sheet or web of material with zero clearance between at least a portion of the outer peripheries of the two articles.
