Abstract

An apparatus for cleaning a roller nip in rotary printing machines, which is filled with a fluid, includes at least one nozzle arranged above the liquid in the nip with the nozzle oriented at an angle (.alpha.) with respect to the longitudinal direction of the nip so as to be directed towards the fluid. Blowing air is fed to the nozzle via a control valve and causes the fluid to flow along the nip and off at least one end of the rollers.
