A recirculating document handler having a document restack transport. The transport includes a series of spaced vacuum assisted drive belts for transporting successive documents to a position above a document stacking tray. A sensor is used to note the passage of a document lead edge past an input to the restack transport. After a delay which allows the document to be driven to the position above the stacking tray the document is separated from the drive belts by a knockdown bail and a reduction in the vacuum attraction between the document and the drive belts. The bail comprises a series of rods supported in locations between the drive belts which pivot into contact with the document and drive it into the stacking tray. The rods contact the document near its trailing edge to force the trail edge to the stacking tray.

Document restack transport

A sheet feeder for separating and feeding the bottom sheet in a stack, a biased corrugating ramp being provided to provide a large corrugation in light weight papers for maximum feeder reliability. The corrugating ramp is adapted to be depressed by heavy weight, stiff sheets to allow the sheets to more closely approach the vacuum feed belts and assure adequate acquisition thereby.
