(54) Method and device for cleaning the rubber cylinders of printing presses


(57) The method for cleaning the rubber cylinders of printing presses particularly of the so-called bobbin type, comprises the succession of the following working phases:
  • Uniformly distributed and preferably continuous atomisation onto each cylinder to be cleaned, which rotates continuously, of a fluid cleaning mixture formed by compressed air and by one or more cleaning liquids, in such a manner that the liquid involves the cylinder with very small drops distributed according to a dot mapping, of discrete type and which varies during the time.
  • Maintaining of said atomisation phase for a predetermined time, while the cylinder performs one or more rotations with respect to the zone of atomisation of the cleaning mixture.
  • Doctor scraping of the cylinder downstream of the atomisation zone, in order to remove the dirt diluted by the said fluid cleaning mixture.
