Abstract

This article describes an electrostatic clutching apparatus for stepping paper without step motion of the drive rolls. Steering of the paper is accomplished by optically sensing the edges of the paper with reference to a guide edge, with the duty cycle of the drive pulses to the electrostatic apparatus being varied for steering the paper.
