Abstract
A vacuum transport system includes vacuum plenum having a plenum plate as a part thereof and a belt with an array of holes that align to grooves in the plenum plate over which the belt is driven. A sliding plate on the underside of the plenum plate inside the vacuum plenum contains a series of holes and slots to progressively open or shut holes connecting the grooves to the vacuum plenum to maintain a constant air flow and vacuum pressure in the cross process direction for varying widths of media.
