  • Soft rollers for ink and water feeding rollers used in off-set printing presses
    Patent number: 5222434
    Abstract: A roller for moving one of ink and water through a printing press is disclosed as an elastomeric covering on a solid journal. The elastomeric covering includes spiral lands and valleys adjacent the lands having depths ranging from 0.002 to 0.004 inch for ducting water, and ranging from 0.002 to 0.015 inch for ducting ink. At valley depths of greater than 0.015, ink is carried solely on the lands for the purpose of lubricating the ductor system. One embodiment includes reversed spiral land and valley end segments that direct ink inwardly from the ends of the rollers to prevent ink buildup at those positions on a ductor roller.
