Abstract

In paper handling devices, copy sheet side registration is important and commonly achieved by crossed-rolls. An improved crossed-rolls side registration system may be accomplished by automatically adjusting the angle between the driver of the crossed-rolls and the registration edge using for example a small motor or adjusting the normal force between the driver and idler, or both. A further extension of the improvement would be to automate the process by electrically sensing the paper weight and skew, matching the sensed information with a machine stored look-up table and automatically adjusting the crossed-rolls and registration edge angle or normal force, or both for optimum performance. An advantage of this approach may afford wider latitude in handling paper weight for side registration.
