Translating electronic registration system
摘要:
Position registration of sheets in a feed path is achieved without guides or gates. Laterally separated drive rolls are speed controlled to correct for skew mispositioning. Lateral registration is achieved by translation of the drive rolls transversely to the direction of sheet movement. Longitudinal registration is controlled by varying the speeds of the drive rollers equally. The system reduces the required paper path length to achieve correct registration, thereby allowing higher speed operation.
