Definitions

  • Ralabate. Ronald Zibelli and Melvin A. Klein ABSTRACT Sheet conveyor apparatus for conveying cut sheets through an automatic copying machine.
  • Gripper devices grip the leading edge of sheet material supplied at a sheet feed-in station and drive apparatus move said gripper devices through a predetermined path including an image transfer station at which a developed image is transferred onto said sheet material and an image fusing station at which said image is permanently affixed to said sheet material while said sheet material is maintained in a substantially planar position.
  • Carnming devices release the gripper devices from the sheet material at a sheet feed-out station and sheet feed-out apparatus positioned at the sheet feed-out station and operatively connected to said drive apparatus receive the movement of said sheet material along the predetermined path.
  • a control circuit emits electrical signals for controlling the operation of said gripper devices and sheet feed-out apparatus to enable sheet material to be continuously conveyed through the aforementioned stations.
