ABSTRACT:
Apparatus for feeding a web of material provided with register marks comprises a rotating delivery device and a sensor which responds to the register marks and provides signals for controlling a feed adjusting device. The sensing point of the sensor is located so as to rotate with the delivery device and be positioned adjacent the web to enable reading of the register marks. The delivery device comprises a pair of rollers of unequal circumference, one of the rollers being driven by a one-way clutch and the other roller being selectively driven by a second clutch which is energized in response to the output of the sensor.
