Definitions
- the invention relates to a device and a method for reworking a printed by an electrographic printing or copying carrier material having a smoothing device.
- the smoothing device has a lateral surface which is in contact with the toner, which has been heated by a fixing device, of a printed image produced on the carrier material and exerts a pressing force on the heated toner.
- the document DE 10 2004 056 000 A1 discloses a device for reworking a printing material web printed by an electrographic printing or copying device, in which the printing material web is carried out between two smoothing rolls, which are arranged in the feed direction of the printing material in the immediate vicinity of a fixing device.
- the smoothing rollers press with a predetermined pressure on the toner heated solely by the fixing device.
- This device also has cleaning devices to remove dirt particles from the smoothing rollers. During the cleaning process, a moistening substance can be brought into contact with the smoothing rollers via the cleaning devices at the same time. This allows simultaneous cleaning and wetting of the smoothing rollers.
- the cleaning effect not or only slightly influenced.
- the applied to the smoothing rollers amount of moistening substance is not or only to a limited extent changeable, without affecting the cleaning effect.
- the dirt particles to be removed from the smoothing rollers with the aid of the cleaning device can impair the supply of the moistening substance to the surface of the smoothing rollers.

Due to the local separation of the cleaning area and the fluid application area, the fluid can simply be applied to the cleaned lateral surface and distributed uniformly over the width of the lateral surface.
- Impurities on the lateral surface do not influence the fluid application.
- a uniform fluid film can be produced on the mantle surface.

Contamination of the application device and an influence of the order of the fluid by the dirt particles are thereby effectively avoided. In particular, this increases the service life of consumables of the application device.
- the fluid preferably has no significant viscosity and state changes in the temperature and temperature changes that occur during the finishing operation.
- means are provided to the outer surface of the smoothing device at a standstill of
- Support material in particular during pressure stop and / or in a process-related withdrawal of the carrier material to withdraw from this, so that damage, in particular by the application of undesirably large amounts of the fluid to a point of the carrier material can be avoided.
