ABSTRACT:
Apparatus is provided for transporting a sheet in a predetermined path of travel. The apparatus comprises a plate having a lower surface extending parallel to and defining the path of travel, and having an aperture formed therein. In addition, the apparatus comprises sheet feeding structure, including a first pair of rollers spaced apart from one another and an endless belt looped about the first rollers, wherein the belt has a lower belt run extending between the first rollers and beneath the plate. Further, the feeding structure includes instrumentalities for driving one of the first rollers for moving the lower belt run at a constant velocity in the direction of the path of travel. Moreover, the feeding structure includes a second pair of rollers which are disposed beneath the plate and are made of a compliant material. Still further, the feeding structure includes structure for resiliently urging the compliant rollers toward the path of travel for urging a sheet feed to the apparatus into contact with the belt and the lower surface of the plate, whereby the belt engages and feeds the sheet at a constant velocity with a portion thereof in the path of travel when fed past the aperture.
