US Patent:

6802255, Oct 12, 2004

Filed:

Dec 9, 2002

Appl. No.:

10/314738

Inventors:

James J. Keller - Scottsdale AZ
David N. Clay - Flower Mound TX

Assignee:

Color Control Corp. - Scottsdale AZ

International Classification:

B41F 3105

US Classification:

101365

Abstract:

An ink fountain mechanism for adjustably metering the thickness of of ink in a plurality of zones axially across a fountain roller for a printing press 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 ink receiving fountain roller. 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 actuatable between a minimum position, providing a minimum ink metered thickness, and a maximum position, providing a maximum metered ink thickness.

Abstract:

An apparatus for continuously providing dampening fluid to a plate cylinder of a lithographic printing press includes a frame operatively connected to the printing press. A dampening fluid reservoir is attached. A pan roller is rotatably mounted in the frame and is disposed in contact with dampening fluid in the dampening fluid reservoir. A transfer roller set tangentially contacts and is parallel to the pan roller. The transfer roller is rotated by friction from the pan roller which is driven at a rotation speed proportional to the speed of the plate cylinder. An ink receptive oscillating roller having a resiliently compressible surface is tangentially contacting and parallel to the transfer roller. The oscillating roller is gear driven at a rotational speed proportional to the speed of the plate cylinder. A water form roller is rotatably mounted in the frame tangentially contacting and in a parallel relation to both the plate cylinder and the resiliently compressible surface of the ink receptive oscillating roller for carrying an even metered layer of water from the oscillating roller to the plate cylinder.
