The controller and method of the invention generate control instructions for a rotary machine that coats bottles. Gas is supplied to processing stations holding the bottles via a pressure management system. The processing stations are centrally controlled by a programmable PLC or microcontroller with an input device and display terminal. Since rotary machines need to be controlled differently depending on the type of bottles and the type of coating, different programs should be interactively created using the input device and display terminal, which then control the individual components of the rotary machine and the processing stations during the coating process. This eliminates unnecessary errors resulting from preparation of the different programs individually by a normal user.

In the method for coating substrates the substrates are placed in recesses in a glass-ceramic plate or plates arranged over infrared high-temperature radiators with the surfaces to be coated on the radiators. The substrates are heated from below to the process temperature required for the coating. Subsequently the substrates are removed from the heating device, introduced into a coating chamber and coated. The preheating device for the substrates has two glass-ceramic plates that are placed loosely on top of each other and infrared high-temperature radiators. Substrate receptacles are provided in the glass-ceramic plates by approximately coincident recesses of different size in the plates so that the substrates can be held in close proximately to the radiators during the preheating.
