1. Apparatus for partially coating the inner surface of light bulbs (5) for reflector lamps, with a radiation-reflecting material (13), comprising a vaporiser coil (14), a radiation-reflecting material (13) which is to be vaporised to produce the coating, and which is in contact with the vaporiser coil (14), and a shade (11) which screens that part of the light bulb (5) which is not be coated from the vaporiser coil (14) and from the vaporising, radiation-reflecting material (13) during the vaporisation of the radiation-reflecting material (13), where the light bulb (5) can be evacuated order to produce the coating, and where the shade (11) and the vaporiser coil (14) can be introduced into the light bulb (5) in mechanised fashion, seperately and consecutively for the coating process, and can be removed in reverse order from the light bulb (5) after the coating process, characterized in that the shade (11) is of inalterable, cup-shaped form and consists of a ferromagnetic material and, for the formation of the coating, is positioned by means of a mechanical gripper (29) on the inner surface of the light bulb (5) and is held by a magnet (12) arranged outside the light buld (5), and after the coating process is removed again by means of the gripper (29). |
