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.
