A coating material to be evaporated in an evaporator cell disposed in a vacuum chamber is fed in the form of a wire to the evaporator cell in accordance with the depth of the molten bath, by a wire transport including a motor-driven shaft or roller and a counter-roller mounted on a movably journaled lever which in turn is movable via an electromagnetic actuator against the force of a spring means. A wire feed tube is arranged between the wire transport which draws fusible wire from a remote supply and feeds it to the evaporator boat where the wire is evaporated for coating a band-type substrate. The feed tube has a straight section which receives the wire concentrically from the transport and a gooseneck section toward said evaporator boat which twice deflects the wire to provide three points of contact with the inner wall of the tube, thus accurately positioning the wire while preventing clogging of the outlet orifice.

Apparatus for reducing the sagging of essentially planar outside walls (3, 13) on a vacuum tank (1) under operating conditions, and for preventing displacements, resulting therefrom, of components fastened to these outside walls (3, 13), such as rollers (7, 8) of a winding apparatus (2) which is movable with respect to the vacuum tank (1) in a vacuum tape coating apparatus, wherein spacers (12, 14) are provided between two opposite outside walls (3, 13).
