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. In operation, the blade members are rotated about respective axes to move their cutting portions downwardly along arcuate paths that preferably pass through the path of the downwardly fed sheet. The arcuate paths of the cutting portions overlap and one of the cutting portions of the blade members is spaced farther from its rotational axis than the other. 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.
