- the spray nozzle can be positioned with high precision.
- Speed sensor associated with a gear motor, and associated with a control or a regulating device, so that the position of a plurality of spray nozzles, the
- Pressure medium cylinders are assigned synchronously can be adjusted.
- Speed sensor detected and regulated by means of the control device. Although the position of the spray nozzles is not

- Spray nozzle 2 assigned exactly one spray nozzle adjustment devices 1, so that the position of the spray nozzle is individually adjustable to the strand width. 1 and 2, two positions of the spray nozzle 2 are shown at several spray nozzle adjustment devices 1, wherein the
- dashed representation of the position of the spray nozzle 2 at a maximum width of the strand 3 corresponds.
- FIG. 4 shows in detail a spray nozzle adjusting device 1 according to the invention for positioning a spray nozzle 2.
- the spray nozzle adjusting device 1 comprises a displacement device 6, a spray nozzle holder 4 and a spray nozzle 2, wherein the displacement device 6 as a hydraulic linear drive, concretely as a
