Abstract
A polymeric printing member for use in a printing machine is provided. The polymeric printing member-includes a substrate and a coating applied to the substrate. The coating is applied to the substrate by rotating the substrate about its longitudinal axis and applying the coating from an applicator to the substrate in a spiral pattern in a controlled amount so that substantially all the coating that exits the applicator adheres to said substrate.
Claims28
A method for manufacturing a polymeric printing member for use in a printing machine, said method comprising the steps of:
- providing a generally cylindrically shaped substrate;
- rotating the substrate about a longitudinal axis thereof in a substantially horizontal direction;
- and
- applying a coating from an applicator in a stream in a generally vertically downward direction to an outer periphery of the substrate, said stream contacting the outer periphery of the substrate at a position substantially above a horizontal centerline of the substrate and contacting the outer periphery of the substrate at a position spaced from an uppermost location of the substrate in the direction of the rotation of the substrate, whereby the dynamics of the rotation of the substrate and the position of the stream on the substrate assist in the uniform distribution of the coating onto the substrate.
A method for manufacturing a polymeric printing member for use in a printing machine, said method comprising the steps of:
- providing a generally cylindrically shaped substrate;
- rotating the substrate about a longitudinal axis thereof;
- and
- applying a coating from an applicator to the substrate in a controlled amount so that substantially all the coating that exits the applicator adheres to the substrate and so that a thickness of the coating may be accurately controlled, whereby the member may be used without the need for further machining of the member.

- and
- applying a coating from an applicator to the substrate in a controlled amount so that substantially all the coating that exits the applicator adheres to the substrate;
- and
- positioning a flexible guide with a free end thereof in a flexed condition with the coating being positioned between the free end of the guide and the substrate to evenly distribute the coating onto the periphery of the substrate.
