Abstract
A self-cleaning web-threading apparatus for a web-fed printing press includes guide rails, a web leader, driver and a detergent supply. The guide rails define a web guideway along which a web is to be threaded through a printing press. The web leader travels along the web guideway in sliding engagement with the guide rails for threading the web through the press. The web leader is fabricated at least partially from a detergent-absorbent material for sliding contact with the guide rails. The driver drives the web leader along the web guideway. The detergent supply is disposed in a selected position on the web guideway for supplying a detergent to the web leader traveling along the web guideway to impregnate it with the detergent. The guide rails are cleaned by the detergent-impregnated web leader as it travels in sliding contact therewith.
