ABSTRACT:
Two chain-type endless belts are positioned to transversely span a continuously moving strip-like web, one belt facing each of the two major web surfaces, the belts oriented at an acute angle to the longitudinal web axis. Disk-type freely rotatable cutters are mounted on the endless belts for movement across the web with the blade cutting axes aligned perpendicular to the longitudinal web axis, and the endless belts are synchronized to provide cooperation between an individual blade on one belt and a corresponding blade on the other belt to engage and shear the web in a "scissoring" action. Another endless belt engages the last cut longitudinal web edge to provide biasing against unbalanced forces parallel to the major web surfaces produced by the blades.
