| 摘要 |
The invention relates to a nozzle system for the treatment of web-shaped material, especially metal strip, comprising nozzle surfaces ( 1, 1*, 1** ) each having a plurality of nozzle apertures ( 1 a), disposed at least on one side of the web-shaped material and located successively in the direction of transport of the web-shaped material. The nozzle system is characterised in that the nozzle surfaces ( 1, 1*, 1** ) are bordered in groups by slit-shaped nozzles ( 3, 3*, 3** ) running transverse to the direction of transport of the material.
