Abstract
The device comprises a suction chamber (41) having a mouth facing toward the cylinder and a nozzle (44) which is associated with the suction chamber and by which a jet of a cleaning liquid is generated. At least a first drying chamber (45, 47) is also provided, associated with said suction chamber (41) and connected to a suction pipe (43).
Claims17
Device for washing a surface of a rotating cylinder, comprising a suction chamber with a mouth facing toward the cylinder;
- a nozzle in said suction chamber, said nozzle being constructed and arranged to generate a jet of a cleaning liquid;
- at least one first drying chamber adjacent to and downstream of said suction chamber, wherein said at least one first drying chamber is connected to a suction pipe;
- and at least one second drying chamber adjacent to and downstream of the at least one first drying chamber.
A printing assembly comprising
- a rotating transfer cylinder for transferring ink from an ink applicator to a substrate to be printed;
- a washing device for washing the cylinder, said washing device being positioned adjacent said cylinder and including a suction chamber with a mouth facing toward a surface of said cylinder, a nozzle in said suction chamber, said nozzle being constructed and arranged to generate a jet of a cleaning liquid onto said cylinder;
- at least one first drying chamber having an aperture adjacent to the mouth of the suction chamber, the at least one first drying chamber being adjacent to and downstream of the suction chamber relative to a direction of rotation of the cylinder;
- and
- at least one second drying chamber adjacent to and downstream of the at least one first drying chamber.

Device for washing a surface of a rotating cylinder comprising
- a suction chamber having a mouth facing toward the cylinder, said chamber including therein a first liquid blowing nozzle directed toward said cylinder so as to blow a cleaning liquid against the surface of the cylinder to detach dirt from said cylinder, said suction chamber being constructed and arranged to substantially remove said dirt from the surface of the cylinder by said suction chamber following detachment;
- and
- at least one drying chamber adjacent to and downstream of said suction chamber, said at least one drying chamber being connected to a suction pipe, and said at least one drying chamber having associated therewith at least one air blowing nozzle which generates a flow of air which operates in combination with said suction pipe to dry said surface of said cylinder.
