Abstract:
A method for cleaning guide rollers of a web printing press having a printing material web guided a plurality of guide rollers, the method comprising the steps of:a) filling a first container with cleaning liquid; b) guiding the printing material web along said first container such that the printing material web directly contacts the cleaning liquid, wherein cleaning liquid is accepted by the printing material web via an elastically deformable sealing lip disposed on said first container; c) passing the printing material web, following step b), past the guide rollers to contact the guide rollers with portions of the printing material web having accepted cleaning liquid; d) creating a difference between rotational velocities of the guide roller and a velocity of the printing material web past the guide rollers to produce slippage between the printing material web and a surface of the guide rollers, whereby soiling of the guide roller surface is removed by the printing material web.
