Embodiment Construction

[0023] As an example of a cleaning device, the device shown in FIG. 1 corresponds to the device described in US Patent 4,236,450, the content of which is incorporated herein by reference. In this device, a wiping roller 1 rotating around an axis 1a in the direction of arrow F1 is in contact with a plate-supporting cylinder 2 of the printing press. The wiping roller 1 is located partially inside the container 3 in which the cleaning device is installed. The device also includes several cleaning elements formed by scrapers 4 , 5 and brushes 6 . The cleaning element extends over the entire length of the wiping roller 1 and acts on its periphery in order to mechanically remove most of the oil film from the periphery of the roller. The device also comprises rows of nozzles 7, 8, 9, 10, 11 and 12, parallel to the axis of the wiper roll 1, for dispensing a cleaning solution (as described for example in US Patent 5855787 or European Patent Application No. 0927632). ) is sprayed onto...

Abstract

The nozzle has a channel (24) in which a cleaning solution is injected under pressure, and an outlet (26) through which the solution is sprayed against a cylinder. The outlet (26) is formed by a first part (23) and a second part (25, 31), said second part (25, 31)being movable with respect to said first part (23) in order to vary the size of said outlet (26).

Description

technical field [0001] The invention relates to a nozzle for a cleaning device for cleaning a wiping cylinder of a printing press. Background technique [0002] Cleaning devices for printing presses are known in the art. For example, US patent 5390598 discloses a wiping device for a gravure printing machine comprising a wiping roller and means for continuously cleaning said roller. The principle and basic technical features of the wiping device described in this patent are incorporated by reference in this application. The device comprises: a container for receiving a cleaning liquid continuously acting on the wiping roller; a cleaning element in contact with the outer periphery of the wiping roller, the cleaning element comprising a brush and / or a wiping blade and at least one A row of nozzles parallel to the axis of the wiping roller, the nozzles being arranged to spray cleaning liquid into the area where the cleaning elements come into contact with the wiping roller. T...
