Einstellbarer Schneid- und Perforiervorrichtung

摘要

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. The accessory includes first and second shafts (70,75) rotatably mounted within a housing, the second shaft (75) being positioned in the same plane of the first shaft (70); a perforator unit (53,80) having a first portion (53) thereof mounted for transverse movement along said first shaft (70) and a second portion (80) thereof mounted for transverse movement along said second shaft (75), said first portion (53) of said perforator unit including means (55) thereon which contacts said second portion (80) of said perforator unit as said first portion (53) of said perforator unit is moved along said at least one first shaft (70) so that said second portion (80) of said perforator unit moves in unison with said first portion of perforator unit as said perforator unit is moved to a predetermined location.
