  • Arrangement for the automatic and continuous adaptation of the document acceptance rate to the document output rate of document output devices
    Patent number: 6102392
    Abstract: An arrangement for the control of movement of documents to an output device such as a printer or a copier in such a manner that the document draw-in rate automatically matches the document output rate. A document intake channel forces the incoming document into a curvature transversely to the direction of the transport of the documents, whereby the degree of curvature of the documents is a function of any tensile force on the documents. A sensor includes an analog and continuous output signal to affect a continuous change of the driving frequency for a motor causing the movement of the documents as a function of the actuation of the sensor.
