Abstract

Abstract An operational function, such as the exposure of a photographic image, is performed on a continuously moving web, such as a photosensitive paper, so that the operations are synchronized to act on predetermined portions of the web. The timing of the operations with respect to the positional orientation of the predetermined web portions may be adjustably varied to achieve precise registration without stopping the web. This may be accomplished by providing an electrical pulse indicating that a predetermined web portion is approximately registered in a station wherein the operation is to be performed, providing a train of electrical pulses having a frequency which is synchronized with the speed of the web through the station, providing an actuating signal for effecting the operation on the occurrence of both a pulse of the pulse train and the firstmentioned pulse in a predetermined relation to each other, and adjustably varying the phase of the pulse train with respect to the passage of the predetermined portion of the web through the station so that the occurrence of the actuating signal may be synchronized with the instant that the predetermined web portion is in precise registration therein.
