DEVICE AND METHOD FOR COATING OBJECT WITH MEDIUM

PROBLEM TO BE SOLVED: To improve a device and a method for coating an object with a medium.SOLUTION: The device has a flowing out opening part, a medium flows out from there, thereafter the medium is sprayed as a spray beam having a main beam direction and a beam profile. The beam profile of the spray beam can be formed by a pair of fixedly arranged beam forming unit, facing in a radial direction to the flowing out opening part, directing forming liquid to the spray beam via at least one forming liquid opening part. At least other one pair of beam forming unit facing in a radial direction are arranged in another angle position relating to the axis of the flowing out opening part to change angular orientation of the beam profile around a main moving direction of the spray beam while maintaining precision needed for automated coating, the beam forming unit can be driven independently from the first pair of beam forming units.
