    摘要: In a continuous dampening system, an oscillating distributor roller distributes ink/dampening fluid emulsion preferably over the form roller. The drive for causing distributing motion, back and forth along its axis of rotation, of the distributor roller is derived by friction drive to the roller surface and the support shaft of the distributor roller is also rotatably driven through appropriate gearing, thus rotation of the distributor roller is varied along with the rotational speed of the other rollers of the dampener, but the rate of longitudinal oscillation remains relative, since the speed of relative motion between the shaft and distributor roller itself increases or decreases proportionately as the press and dampener speed up and slow down. The distributor roller is held and controlled within a sub-frame structure with adjustments to achieve a uniform "stripe" contact between the distributor roller and the form roller, and the distributor roller can be moved, without disturbing its fine adjustment or trim, between an active position contacting the form roller and a inactive position where the distributor roller is out of contact with the form roller.

    摘要: A continuous seal type lithographic dampener is fitted with a one-piece metering roller which has a continuous surface coating of flame sprayed (as by plasma arc) chromium oxide particles providing a porous surface which is filled with a pore occluding sealer. The resulting cylindrical surface is than ground to a finish in the order of 20 to 30 micro inches. A finish coat of sealer is applied to the surface of the roller. The resultant metering roller is highly wear resistant and hydrophobic, having a surface energy in the order of 30 to 40 dynes/cm.
