Abstract
A conveyor belt for transporting articles having a plurality of apertures therein such that a vacuum applied to the apertures aids in forcing articles to stay on the conveyor belt while the articles are being translated. The conveyor is particularly useful for moving sheet articles such as a sheet feeder removing sheet articles from the bottom of a stack of sheet articles in a sheet feeder. The vacuum adds to the frictional force of the article on the conveyor belt and increases the productivity of the sheet feeder by reducing jams and increasing the frictional contact of the sheet article on the conveyor belt by removing chaff and other material form the conveyor belt.
