Abstract: The cutting apparatus and method of the present invention involve feeding a newsprint wrapper or any other sheet of paper downwardly along a planar path between two rotating cutters. Each of the cutters includes a planar blade member with an outer, sawtoothed cutting portion.

It is also moved tangentially faster about its axis than the cutting portion of the other blade member. In this manner, a cutting action is produced which first punctures and then subsequently tears or shreds a horizontal cut across the downwardly fed sheet to cut it into smaller pieces or segments.
