Abstract: An apparatus for applying a coating to a surface of a substrate which includes a feeder for feeding the coating to a predetermined position, a roller for applying the coating onto the surface of the substrate to be coated from the feeder and a doctor for regulating a thickness of the coating applied to the roller, the doctor having a rake surface, a facing surface and a flank surface forming an escape angle with the facing surface confronted with the surface of the roller. The escape angle defined between a tangential plane with which the roller is contacted and an extension plane of the flank surface at an intersection defined between the extension plane and the roller is an obtuse angle.

Abstract: A metallizing apparatus vacuum deposits a metal onto a workpiece. Filaments having a metal thereon extend between a pair of electrode rods and are heated by conduction of electric current. The end portions of the filaments are secured to the respective rods by a securing apparatus which includes a support member, an interposed member, and a depressing bolt. The support member is fastened to an electrode and has a recess facing the electrode. The interposed member is in the recess and has extended positions which guide it along an axis toward and away from the electrode. The interposed member has a fitting groove for receiving an end portion of a filament. The fitting groove is in a face of the interposed member which faces the electrode. The opposite face of the interposed member is in contact with an end of the depressing bolt, which passes through the support member into the recess and presses the interposed member to press the filament against the electrode.
