Abstract (en)

The intermediate transfer roller, in an electrostatograph machine, has a core unit (82) as a cylindrical roller core (81) with at least one pliable mantle cladding (86). A replaceable sleeve (89) can be removed from the core unit, as a continuous belt around the core unit and in close contact with it. The intermediate transfer roller, for an electrostatograph machine, has a removable sleeve with a non-pliable reinforcement cladding (85) to support a pliable cladding (87). An optional barrier layer (83) can be on the outer surface. The pliable layer around the roller core is of an elastomer material, together with a stiffening layer (88) in close contact. The sleeve carries a specification marking. An Independent claim is included for a production process, for the intermediate transfer roller, where a continuous sleeve is applied to the core unit with a close contact. Preferred Features: The sleeve is stretched over the core unit, and then relaxed to fit tightly around the core. The sleeve material has a pliable fabric layer (87) with a module of elasticity of 0.1-10.0 MPa, and a lateral stretch count of 0.2-0.5. The fabric is coated with the outer non-pliable barrier layer. The reinforcement is a strip with an inner surface roughness of ≤ 2 micrometer. The reinforcement material contains an antistatic agent.
