ABSTRACT:
A circular rotary slitter construction comprises a body hub having a circular perimeter and at least one axially facing surface. A cutting edge hoop cylinder is fixedly mounted on the body hub perimeter. At least that portion of the axially facing surface contiguous to the hoop cylinder is axially inset from an annular cutting edge of the hoop cylinder so that the annular cutting edge margin of the hoop cylinder overhangs the contiguous axially facing surface cantilever fashion and the cutting edge is axially outwardly spaced relative to the contiguous axially facing surface. The hoop cylinder is adapted to be made from tool steel and the body hub is adapted to be made from a more easily machined material such as aluminum and at least partially from a suitable plastic material.
