Sich selbst einstellende Spaltdichtung zwischen zwei gegeneinander beweglicher Bauteile

摘要

The method for automatically producing a gap seal between the end of a suction roller (1) and a control valve (5) comprises:placing them in contact; and#starting up the roller which has an abrasive surface (10) on its end and abrades a graphite surface (11) on the valve. This minimizes the size of the gap produced. An independent claim is included for a mechanism for carrying out the method.
