Abstract
A carbon fiber roller core coated or covered with an outer nylon or outer chrome surface for use in a printing press, and a method of making and the method of using same are disclosed. The advantages of a light weight roller for shipment, handling and roller replacement are provided. Also the desired nylon or chrome surface for use in the printing press, such as the press inking or water system is also provided.
Claims39
A method for creating a carbon fiber roller core for use in a printing press to provide an outer surface thereon suitable for use therein, comprising the steps of:
- obtaining a carbon fiber roller core;
- checking the carbon fiber roller core for defects;
- applying an intermediate covering to the carbon fiber roller core;
- and
- applying a desired nylon or chrome outer coating to the outer surface of the intermediate covering;
- whereby the formed carbon fiber roller core with the intermediate covering and desired nylon or chrome outer coating can be used in the printing press.
The method as in claim 3, wherein said step of applying said desired outer coating is spraying a nylon.
A carbon fiber roller for use in a printing press having one of a nylon or chrome outer surface applied thereto.
A roller for use in a printing press having a carbon fiber core and one of a nylon and chrome outer surface or said carbon fiber core.
A method for forming a nylon coated carbon fiber roller for a printing press comprising the steps of:
- (a) beginning with a carbon fiber roller core of a first configuration;
- (b) turning the carbon fiber roller core to a second undersized configuration;
- (c) checking the turned carbon fiber roller core for defects;
- (d) providing an epoxy covering over an outer surface of the carbon fiber roller core;
- (e) heating the carbon fiber roller core with epoxy covering thereon to a desired temperature to make the epoxy covering receptive to a subsequent nylon coating without thermally damaging either the epoxy covering an/or carbon fiber roller core;
- (f) spraying the subsequent nylon coating onto the epoxy covering on the carbon fiber roller core;
- and
- (g) finishing the nylon coating on the carbon fiber roller core to the desired size for use in a printing press.
