ABSTRACT:
A paper knife is mounted at its opposite ends on a pair of arcuate arms pivotally attached to the knife table. The knife is operated by a fluid cylinder which extends from the table to the knife. This way all of the operating apparatus is positioned beneath and not above the table, thereby providing a low profile so that the operator may reach over the knife. Various mechanical details enable quick paper sets and closer cuts.
