ABSTRACT:
An area of an insulating strip (3) which is to remain free of metal is covered by an endless cover strip (4), which rests on the insulating strip (3) and travels along with it at the same speed. Before it enters a vapor deposition zone (5), the cover strip is provided with a film of oil on the side facing the metal evaporator (6) and, after the cover strip (4) has passed through the vapor deposition zone (5) and after the cover strip (4) and the insulating strip (3) have been separated from each other, the oil which has been deposited from the vapor phase onto the cover strip (4) is removed by heating the cover strip (4) with a heater (7) installed in the immediate vicinity of the cover strip (4).
