Abstract
A low cost, modular, top adjustable slitter/perforator accessory for a machine that feeds paper to an output station is disclosed. The slitter/perforator is positioned just prior to the output station and when actuated places desired combinations of slits and/or perforations in paper passing through it. The accessory allows infinite location adjustments of slits and/or perforations along the width of paper by an operator while the machine continues to transport the paper. The slitter/perforator is automatically shut off when paper is directed to the machine's finisher.
