  • Paper feeding roller
    Patent number: 4084807
    Abstract: A sheet-feed roller system that employs an annular deformable resilient roller eccentrically mounted on a shaft for rotation whereby rotation of the shaft brings the roller into contact with sheets only when they are to be fed by the roller in order to increase the feed force while minimizing the pressing force on the sheets to thereby reduce sheet misfeed.
