Abstract

The invention relates to a device and method for processing a rotating printing technique surface by treating liquid. A device for processing a rotating printing technique surface, especially a printing form capable of re-imaging, by treating liquid (11), such as cleaning liquid, coating liquid or flushing fluid, comprises multiple nozzles (6a-6e) and a cloth device (4). All the nozzles are disposed along a line which is approximately parallel with the rotating axis of the printing technique surface in a way capable of swaying; the cloth is disposed approximately parallel with the rotating axis. The invention is characterized in that: the nozzles are constructed as ejector nozzles which can respectively sway around an axis (13) approximately perpendicular to the rotating axis; the swaying of the ejector nozzles can produce the approximately uniform distribution of the treating liquid parallel with the rotating axis in a favorable way; the cloth device is optimally to operate with a cloth (5) which has some sections (19, 25), such as calender section, approximately parallel with the extension of the rotating axis; the diffusion of the treating liquid parallel to the feeding direction (19, 25) in the cloth is basically limited, and the uniform distribution of the treating liquid parallel to the rotating axis is supported.

Description

technical field [0001] The invention relates to a device for treating a rotating printing surface with a treatment liquid, comprising a plurality of nozzles and a cloth device, the nozzles being pivotable along a line substantially parallel to the axis of rotation of the printing surface Arranged, the cloth device is arranged substantially parallel to the axis of rotation. [0002] Furthermore, the invention relates to a method for treating a rotary printing surface with a treatment liquid, wherein the treatment liquid is delivered by a plurality of nozzles which can be moved along a line substantially parallel to the axis of rotation of the printing surface. The arrangement is pivoted and the treatment liquid is at least partially received by a cloth of a cloth arrangement which is arranged substantially parallel to said axis of rotation. [0003] The invention also relates to a method for treating a rotary printing surface with a treatment liquid, wherein the treatment liqu...
