ABSTRACT:
A non-tilt cheek assembly is provided for use in an ink fountain assembly. An ink fountain mechanism for adjustably metering the thickness of the layer of ink in a plurality of zones axially across a fountain roller for a printing press. The ink fountain mechanism includes a plurality of metering blocks, horizontally aligned and axially adjacent to one another with side-by-side upper support surfaces forming a substantially continuous support surface along the length of the fountain roller. Each upper surface of the metering blocks is adjustably spaced from the fountain roller to control the amount of ink, in a zone corresponding to the side-to-side length of the support surface of each metering block. A plurality of adjustment bolts are each separately and threadably engaged with each of the plurality of metering blocks. The adjustment bolts are slideably supported in a main beam that extends the length of the fountain roller. A plurality of lever-actuated cams are pivotably held adjacent to the heads of each of the adjustment bolts. Metering cams are engaged with the heads of the adjustment bolts and are progressively actuatable between a minimum position, providing a minimum ink metered thickness, and a maximum position, providing a maximum metered ink thickness. A replaceable liner is provided and a pivot mount having an operating position with the replaceable liner immediately adjacent to the fountain roller and a liner replacement position with the liner pivoted away from the fountain roller so that it can be conveniently removed.
