ABSTRACT:
A sheet feeding system includes a first conveyor and a second endless, clamp conveyor wherein the first conveyor includes an endless belt and an idler roller which is biased toward the belt and adjustably mounted along the belt relative to a clamp on the endless, clamp conveyor. The roller is spaced from the clamp a distance approximately equal to the length of a sheet being conveyed so that the sheet remains in a nip between the idler roller and the belt until the leading edge of the sheet is driven into the clamp and the trailing edge of the sheet clears the nip so that the sheet is not driven further into the clamp.
