Abstract
The invention relates to an evaporator device with a receptacle for holding material to be evaporated. With this evaporator device an oil film can be applied onto specific sites of a sheet to be coated, this sheet being coated with aluminum or zinc in a further step. At the sites at which the oil film is located, no aluminum or zinc is deposited. With the aid of a rod valve, precise application of the oil onto the sheet is ensured. This rod valve is driven by a stepping motor, which can release percentage fractions of oil vapor.
