  • Patent number: 6868608
    Abstract: Printing plates are mounted onto a cylinder by first establishing a temperature difference between the plate and the cylinder; in particular, the temperature of the plate exceeds the temperature of the cylinder. The plate is then wrapped around the plate cylinder, and the temperature difference causes the plate to shrink against the cylinder.

  • Patent number: 6602368
    Abstract: A method of coating core having a metal surface with a uniform thickness, smooth, thin layer of fluorinated polymer calls for inserting the core into a sleeve of the polymer. The sleeve has an inner diameter slightly smaller than the outer diameter of the core so that the sleeve stretches to form a skin-tight fit over the core upon insertion. The assembly of sleeve and core is then subjected, in sequence, to aging under vacuum at a temperature below the softening point of the polymer prior, heating to a temperature above the softening point, and cooling below the softening point to thermally bond the fluorinated polymer to the metal surface. A firm bond is achieved without additional adhesive components or etching of the surface. A fuser roll for suitable for electrophotographic copy machine service can be prepared by this method without the need for a separate, post-bonding burnishing step to smooth the exposed surface of the fluorinated polymer layer.
