"ROTATABLE CUTTER MECHANISM FOR CUTTING DIFFERENT LENGTH NOTCHES IN A MOVING WEB" ABSTTRACT OF THE DISCLOSURE The cutter mechanism includes a fixed cutter having side notches therein over which either a sheet, strip or an endless web of paper travels at a preselected speed. A pair of rotatable cutters are mounted on shafts for rotation in timed relation to each other and to the speed of the sheet, strip or web. The rotatable cutters are positioned on opposite sides of the fixed cutter. Each of the rotatable cutters has a first radially extending cutter blade and a second radially extending cutter blade arranged longitudinally along the shaft and adjacent to each other. One of the radially extending blades is adjustable angularly relative to the other. The relative radial angle between the blades determines the length of the notch cut by the respective rotatable cutters in the side of the sheet, strip or web.
