Abstract
A system for feeding and transporting documents includes a feeder stage and a transport stage. Documents are fed singly, in order, from a stack of documents in a hopper assembly. A flag/flag block arrangement provides a force to move the documents along the hopper floor toward the feeder and to feed a document with a presentation force. The flag block includes a horizontal element for concentrating the presentation force at a desired position at the feeder. The horizontal element has sufficient depth away from the feeder such that the documents are essentially free to expand, thereby concentrating the presentation force while reducing drag forces. The flag/flag block arrangement is useful, for example, when the system is used to process envelopes.
