ABSTRACT:
An adjustable mounting mechanism for a distribution roller in a printing, duplicating or like machine which includes a moisture or ink system having a plurality of distribution rollers for distributing moisture or ink to a printing couple of the machine. A pair of fixed rollers and a removable roller are located on the machine in a triangular configuration with parallel axes of rotation. The adjustable mounting mechanism includes a triangulated array of pivot arms movable generally perpendicular to the axes of the rollers. Two of the pivot arms define a V-shaped yoke to cradle the removable roller, and the other pivot arm defines a clamp for holding the removable roller in the cradle. Each of the other two pivot arms and, therefore, the removable roller is adjustable generally radially toward and away from the respective fixed roller to adjust the pressure or gap between the removable roller and the respective fixed roller. The clamp arm is spring loaded to permit adjustment of the other two pivot arms and, therefore, the removable roller while the removable roller is held by the clamp arm.
