ABSTRACT:
Apparatus for transporting and processing documents and maintaining a preset nominal inter-document gap, g.sub.nom therebetween, this apparatus including transport stage for picking each document from an input stack and advancing it toward a destination at a controlled rate; a sensor unit for sensing the distance g between the so-moved document and the following document; and a control stage for determining the variance .gradient.g, between g.sub.nom and g, while driving each successive document along a feed path from the input stack at adjustable times; with the sensor unit inputting the control means which is adapted to responsively determine the variance-distance .gradient.g, and to thereupon control the transport stage to adjust the acceleration or deceleration of a following document and so tend to reduce this variance-distance .gradient.g.
