ABSTRACT:
An apparatus for controlling the registration between a printed web of material and a downstream processing station comprising a control unit which further controls a web path register to change the web path length as a function of the output of a print detector monitoring the passage of said web and as a function of an encoder coupled to a web processing station to provide an output signal indicative of the operation of the web processing station wherein said apparatus compensates for error resulting in the registration of the printing on the web due to variations in the printed repeated length of the web extending between both (1) the printing station and the print detector and (2) the print detector and a subsequent web processing station.
