FIELD: technological processes.
SUBSTANCE: method of printing press cylinder cleaning, on which a layer of paint is deposited, which is transferred on printed material, such as paper, plastic film, etc., in which supply of cleaning liquid medium in the form of steam that is able to remove contamination from the corresponding area is provided to the surface of cleaned cylinder, and suction of mentioned contamination is provided from the cylinder surface. Mentioned steam is supplied under pressure in slightly inclined direction in respect to perpendicular to the cylinder surface via tip that is installed in the cavity of cleaning head, at that mentioned suction is carried out directly behind steam jet through the slot in mentioned cleaning head, which partially surrounds the tip and is installed on the external side of mentioned cavity. Device for printing press cylinder cleaning, in particular, flexographic printing press, contains head, which is installed along cylinder length and arranged with the possibility of movement along its axis, tip for supply of washing liquid medium in the form of steam to the area of cleaned cylinder surface, and suction facilities for removal of contamination that has been separated from the cylinder. Steam to tip is supplied under pressure from steam source, which is installed in cavity of mentioned cleaning head and which is oriented with provision of steam jet direction in slightly inclined direction in respect to perpendicular to the surface of cylinder, at that suction facilities represent suction slot, which is installed directly behind the tip, partially surrounding it from the external side of mentioned cavity.
EFFECT: perfect cleaning of cylinder surface without leaving traces of washing liquid remains; cheap and simple in design and may be used with paints of different type.
