ABSTRACT:
A method of making hard rollers for commercial printing presses comprising the sequential steps of heating a cylindrical sleeve of plastic material until it reaches an elastic state, fitting the sleeve into position over a cylindrical metal core having an outer diameter slightly greater than the inner diameter of the cylindrical sleeve, and cooling the cylindrical sleeve. The method may be used to rebuild worn rollers and is simpler and more versatile than conventional methods of making hard rollers including electrostatic spraying of metal cores or securing plastic sleeves by means of adhesive or heating heat shrinkable polymer sleeves.
