Abstract
Method and device for continuously producing a coherent layer of a liquid/melt of even thickness by means of centrifugal action along the entire periphery of a rotating disk (13, 113), liquid/melt being supplied to the disk around its entire axis of rotation from means (12, 112) and leaving the disk as individual droplets. The means (12, 112) distributing the liquid/melt onto the disk (13, 113) has according to the invention essentially the same speed and direction of rotation as the disk, and the liquid/melt undergoes under the influence of centrifugal action circumferentially a spreading and change in velocity across the disk (13, 113) in contact with the same.
