In a method for cleaning cylinders included in a printing system, a roll of cleaning fabric is used. The roll (12) has a bobbin (14) coated with a water repellent, and the cleaning fabric (13) is wound onto the bobbin (14). The cleaning fabric (13) is impregnated with a cleaning composition containing water in a concentration of between 5 and 50 wt %.
A printing system cleaning fabric (13), having a first layer (131) with a first cleaning surface (131′), and a second layer (132) with a second cleaning surface (1321) facing away therefrom. The first and second layers (131, 132) extend parallel to each other and have a respective inner surface (131″, 132″) attached to the other along an extension of the cleaning fabric (13). The first and second layers (131, 132) have different permeability characteristics.

A spray applicator (1) for spraying a fluid onto a web (W) of material has a first group of spray nozzles (10A) arranged along a first axis (FA) and a second group of spray nozzles (11A) arranged along a second axis (SA). The first (FA) and second (SA) spray nozzle axes are arranged on the same side of a plane in which the web (W) is run. Each spray nozzle (10A, 11A) has an elongated spray opening configured to spray fluid in a direction towards the web (W). The first spray nozzle opening of the first group of spray nozzles (10A) has an inclination angle which differs from the second nozzle opening inclination angle of the second group of spray nozzles (11A).

Roll of cleaning fabric and related apparatus and methods
A roll of cleaning fabric is used for cleaning printing cylinders of a printing system. The cleaning fabric (13) is impregnated with a cleaning composition containing an organic solvent and a cellulose solubilizer. The roll may be wound around a core (14) and inserted in a removable sealing bag (15) configured to seal around the roll (12) of cleaning fabric (13) in order to prevent the cleaning composition from evaporating before use.
A service tracking system for a printing press (1), spray applicator (1′) or the like includes at least one replaceable component (10) having at least one memory unit (20). The service tracking system further includes a controller (30) which is connected to the memory unit (20). The controller (30) is configured to control the operation of the replaceable component (10) and to periodically update data stored on the memory unit (20) related to run-time data regarding the operation of the specific replaceable component (10).

Method and apparatus for cleaning printing cylinders
A cleaning fabric wound on a roll (12) is used for cleaning printing cylinders (2, 3, 4) of a printing system (1). The cleaning fabric (13) includes a liquid absorbable material configured to be soaked with a cleaning liquid containing a polar additive configured to make the cleaning liquid polar. The roll (12) of cleaning fabric (13) is included in a cleaning cassette (10) which is movable between an idle position out of contact with the printing cylinders, and an active position in which the cleaning fabric (13) included in the cassette (10) is in contact with a printing cylinder to be cleaned.
