Abstract
A slitting assembly for producing a plurality of 'interrupted cut' slits in a large sheet of sport card photos includes a horizontal support track carrying a plurality of individual upper slitting assemblies each including a freely rotatable upper hub, an upper blade concentrically attached to the upper hub, a resilient band circumferentially disposed on the upper hub to frictionally engage the top surface of the sheet being slit, and an upper blade biasing element to resiliently urge an edge of the upper blade against an edge of the corresponding lower blade. The upper blades are precisely parallel to the lower blades to avoid interference with notches provided in the lower blades to interrupt the slits being made. The locations of the notches are selected to compensate for slippage resulting from the frictional engagement.
