Abstract
A high speed sheet feeder for directing sheets to a host utilization device having a stack feed elevator platform accessed by a drawer provides a feed ramp for supporting a stack of sheets. Sheets in the stack are deshingled by a feeder singulator and driven, typically, downwardly to a feed tray extending remote from the singulator. The feed tray receives sheets in a space that enables formation of a second smaller stack of sheets. The tray further includes an opening adjacent the second stack that enables sheets to be slid from the top of the second stack. The tray is positioned and constructed so that it can enter and be removed from a port in the drawer of the utilization device. The feed tray's positioning relative to the port allows sheets in the second stack to be placed adjacent a utilization device singulator in the drawer so that sheets can be removed by the utilization device singulator for processing thereby. In utilization devices having two drawers positioned one a top the other, the tray can be constructed so that the drawer not interfaced with the tray can be accessed for loading without removing the tray from the other drawer.
