ABSTRACT:
An ink or liquid pickup roller is partially immersed in a bath of liquid and is rotated about a horizontal axis in one rotational sense. An applicator roller spaced from the pickup roller is rotated about its horizontal axis in the same rotational sense. A transfer roller is rotated in the opposite rotational sense about its horizontal axis and radially continuously engages the applicator roller. This transfer roller also is oscillated about the axis of the applicator roller into periodic contact with the roller to receive therefrom a coating of ink or other printing liquid. The transfer roller therefore rolls off the pickup and applicator rollers, but the peripheral velocities of the transfer roller is different from the peripheral velocities of the pickup and the applicator rollers.
