A elastomer-covered roller ( ) is provided with an improved bond coating for bonding the elastomeric cover ( ) to the core ( ). At least one layer of material ( ) is thermally sprayed on the core to form a rough surface having a roughness from 400 microinches R to 2000 microinches R or greater. In a further improvement a denser, less porous layer ( ) may be applied next to the core to protect the core from corrosion, followed by a less dense layer ( ) applied to the first layer and having a similarly rough surface ( ) for good mechanical bonding.

A tubular printing blanket for a blanket cylinder in an offset printing press comprises a cylindrical sleeve, a compressible layer over the sleeve, and an inextensible layer over the compressible layer. The cylindrical sleeve is movable telescopically over a blanket cylinder. The compressible layer comprises a first seamless tubular body of elastomeric material containing compressible microspheres. The inextensible layer comprises a second seamless tubular body of elastomeric material containing a tubular sublayer of circumferentially inextensible material. A seamless tubular printing layer over the inextensible layer has a continuous, gapless cylindrical printing surface. Methods of manufacturing the tubular printing blanket are also disclosed.
