INKING APPARATUS HAVING AUTOMATIC WASH-UP MEANS

摘要

An inking unit, including an ink fountain formed between an inking cylinder and a scraper type doctor blade, is provided with an automatic wash-up system. The latter includes spray pipes having nozzles that direct cleansing and rinsing fluids against the ink engaging elements. Much of these cleansing and rinsing fluids are recirculated to prevent waste, with recirculating being effected by the same pump that delivers ink to the reservoir from which ink is supplied to the fountain.
