Abstract
Provided is a device for printing to a recording medium, as well as a device for turning a recording medium, respectively include a transport roller that includes a base body on the surface shell of which a protective layer is formed. The protective layer includes at least one ruthenium layer. A method for producing a protective layer on a portion of the surface of the base body of a transport roller includes at least the application of a ruthenium layer onto the base body.
Claims18
A transport roller for transporting a recording medium,
- the transport roller comprising:
- a base body;
- and
- a protective layer formed, on at least a portion of a surface shell of the base body,
- wherein the protective layer comprises at least one ruthenium layer, and
- wherein the protective layer comprises at least one zincate layer that is arranged between the ruthenium layer and the base body.
A method for producing a protective layer on a portion of a surface of a base body of a transport roller for transporting the recording medium, the transport roller being arranged downstream of a drying unit for drying an inkjet print image printed onto the recording medium,
- and, a protective layer that comprises at least one ruthenium layer is generated on the portion of the surface of the base body of the transport roller, the method comprising:
- blasting the base body with alumina before an application of the ruthenium layer or another layer,
- and, before the application of the ruthenium layer or another layer, and after the blasting with alumina, the base body is treated via a chemical deposition in a zincate etchant bath, or is treated via a galvanic method, to generate a zincate etchant layer.
