ABSTRACT:
The invention is directed to a sheet gripper structure for use in a copying machine which is affixed to a pair of chains extending between sprockets. The chains include link plates with an improved attachment formed in each of the link plates. A pair of the attachments are secured inside the pair of chains at an interval of the link plates. A sheet pressure rod is mounted on the folded sections of selected ones of the pairs of the attachments in the sheet conveying direction and a sheet retainer is fixed to other selected ones of the pairs of the attachments. The sheet pressure rod carries a pair of symmetrical hold plates inside thereof and a pair of sheet pressure arms outside thereof. The gripper structure comprising the sheet retainer, the hold arm and the sheet pressure arm is installed on the chains, or on a belt conveyor or any other conveyors in such a way to be closed when moving in the straight direction and opened in the process of changing their directions.
