A paper cutter has a cutter bar and rotary cutting blade that cooperate to slit a continuous web of paper passing therethrough across the entire width thereof. A cam is provided on one end of the cutter roll which lifts the cutter bar out of operative contact with the cutter roll and blade for a portion of a revolution of the cutter roll. The cutter bar is spring-urged into contact with the cutter roll and the cutter roll is axially shifted along the cutter bar to move the cam into and out of contact with the cutter bar to selectively disable the slitting of the paper web for a small portion of the width thereof to allow discreet individual portions of the web to remain connected together for further operations at another location. The cutter roll is driven by a motor, and is axially shifted by solenoid lever arrangement to position it relative to the cutter bar.
