Abstract
Apparatus and methods for attaching flexible or magnetic plates onto an imaging cylinder are provided. A drum apparatus of an imaging device includes an imaging cylinder having an outer surface and a magnetic foil attachable to the outer surface of the imaging cylinder. In a configuration with the magnetic foil attached to the outer surface of the imaging cylinder, at least one metal back plate can be attached to the imaging cylinder via magnetic coupling to the magnetic foil. In a configuration without the magnetic foil attached to the outer surface of the imaging cylinder, at least one flexographic plate can be attached to the imaging cylinder.
Claims21
A drum apparatus of an imaging device comprising:
- a non-magnetic imaging cylinder having an outer surface;
- and
- a magnetic foil attached to the outer surface of the imaging cylinder, wherein the imaging cylinder having the magnetic foil attached thereto is configured to retain at least one metal back plate on the imaging cylinder via magnetic coupling to the magnetic foil.
A method of retrofitting a non-magnetic imaging cylinder to receive at least one metal back plate, the method comprising the steps of:
- (a) attaching a magnetic foil on an outer surface of the imaging cylinder;
- and
- (b) magnetically coupling the at least one metal back plate to the magnetic foil on the imaging cylinder.
