Embodiment Construction

[0025] figure 1 First, a first exemplary embodiment of a device 1 for continuous precursor supply according to the invention is shown schematically. The plant 1, as part of a coating plant, in particular a plasma coating plant, has a plurality of extraction devices 2, 3 for supplying metal strips or individual goods (not shown here) The coating module of the coating is not shown here. In the extraction devices 2, 3 of the coating module (not shown here), the precursor 6 is withdrawn, for example atomized, from the inlet lines 2c, 3c of the respective extraction device by the inflow of the process gas 2b, 3b and fed (not shown) out of the coating module. In the inlet pipes 2 c , 3 c , which are at least partially configured as risers, the precursor level P is decisive for the amount of precursor removed by the extraction devices 2 , 3 as a function of the parameters of the process gas 2 b , 3 b. Consequently, the precursor level P in the feed lines 2c, 3c is kept as constant...

Abstract

The invention relates to a method for supplying at least one precursor to a plurality of coating modules of a coating system and to a corresponding coating system, in particular a plasma coating system. The object of the present invention is to propose a method for coating and a simple device for coating, by means of which method or device it is possible to continuously supply a plurality of coating modules with the same precursor level And to ensure continuous operation of the coating operation, this object is achieved by the method according to claim 1 .

Description

technical field [0001] The invention relates to a method for supplying at least one precursor to a plurality of coating modules of a coating plant, wherein the coating module has at least one withdrawal device and at least one input, for example partially configured as a riser The input pipe through which the precursor is delivered to the extraction device of the coating module. Furthermore, the invention also relates to a coating plant with a plurality of coating modules, at least one storage container for precursors, wherein the coating module has at least one extraction device and at least one, for example partially configured as a riser The invention also relates to an advantageous use of the coating device as an input pipe for the extraction device, through which the precursor is supplied to the extraction device of the coating module. Background technique [0002] Especially during the coating of strips, in particular metal strips or steel strips, for example with adh...
