ABSTRACT:
An apparatus for coating both sides of strips in a vacuum with zinc includes a casing which encloses a coating chamber and a winding chamber, a removable cover disposed on at least one side of the casing for pressure-tight sealing the coating and winding chambers, a winding assembly having rotatably supported deflecting rollers, guide rollers, tensioning rollers, and coating drums and a take-off and a take-up roll and evaporating sources disposed in the coating chamber. These evaporating sources are provided with a nozzle lip 60 including two L-shaped profile ledges 63 which are parallel to one another and kept in a spaced-apart relationship by means of tranversely disposed spacing screws 65 and adjusting nuts 66. The width of the nozzle gap 67 formed by the two profile ledges 63 can be changed by turning the adjusting nuts 66 on the spacing screws 65. The nozzle lip is spaced by a slot (S) from a frame part. An elastic sealing member rests firmly against the inner wall of the frame part in the slot and thereby closes the slot.
