NOZZLE ARRAY

A nozzle array for use in the coating of a mobile web-like material has a plurality of high-pressure nozzles ( 2.1, 2.2 ) in the transverse direction of the web. The nozzles ( 2.1, 2.2 ) have been classified by a variable acting on the flow so that the deviation of the variable within the array is s...

More Information
Summary:A nozzle array for use in the coating of a mobile web-like material has a plurality of high-pressure nozzles ( 2.1, 2.2 ) in the transverse direction of the web. The nozzles ( 2.1, 2.2 ) have been classified by a variable acting on the flow so that the deviation of the variable within the array is smaller than a pre-set value. The yield of each nozzle being the same with optimal precision, an optimally even coating is achieved on the web.
