ABSTRACT:
A slow-down apparatus is disclosed using a suction box by itself to slow a sheet of paper in a paper transport apparatus, and to remove the trailing edge of a sheet from the path of the leading edge of an oncoming or following sheet to prevent lead edge damage. A set of high-speed conveyors deliver a sheet above shingled predecessor sheets being drawn by a slowdown conveyor. The shingled sheets "shutter" a suction box beneath them from affecting the delivered high-speed sheet. As the shingled sheets uncover the suction box, the high-speed delivered sheet is affected and drawn to the low-speed conveyor.
