Washing device selectively engageable with plural inking paths

摘要

A rotary printing press has a washing mechanism for washing ink residue off of the roller arrangement therein. The washing mechanism has a washing medium applicator and an arrangement of rollers which comprises a roller that can be positioned to split the flow of washing medium into two paths to direct the flow in essentially the shortest route possible to the distribution rollers located at the plate cylinder. The washing mechanism can also have a doctor-blade device for scraping the soiled washing medium from the rollers, and the doctor-blade device can be activated by the same mechanism which activates the positioning of the roller which splits the flow of washing medium.
