Abstract
A known ink feeder in a printing press, including an ink recovery and circulation system for scraping surplus ink from a roller in a printing unit to return it to an ink reservoir, is improved so as to avoid variations in a moisture content in circulating printing ink caused by an accumulation of wetting water in the ink. The improvements reside in that moisture in the surplus ink is positively separated and removed in the ink circulation system by providing a moisture removing device having a rotary roll containing a heater therein and small diameter rolls held in contact with the outer circumference of the rotary roll.
