20130239883 | ARRANGEMENT FOR THE PRODUCTION OF STRUCTURED SUBSTRATES - An arrangement for producing structured substrates is provided, which includes a device for applying layer systems including a device for applying liquid materials to rotating substrates, a housing, a rotating holder for the substrate to be coated, a feeder for liquid materials to be applied, and a collection device having multiple removal contraptions for liquid materials that do not remain on the substrate. The housing of the device is filled with an inert gas, in particular dried, molecular nitrogen, noble gas, or a mixture thereof. The additional receptacles and conduits of the arrangement for producing structured substrates are gas-tight and are designed such that an inert molecular nitrogen or noble gas atmosphere is created above the liquid contents thereof. The collection device has various collection zones in which different liquid materials can be selectively collected and selectively removed via the associated removal contraption. | 09-19-2013 |
