Abstract

The method involves recognition of a sling displacement of the path by displacement sensor and recognition of the applied quantity to the path by a thickness gage (7). The position of one of the curtain coating heads in lateral direction is controlled by the displacement sensor (6) delivered signals. A dispersion of the completely coated quantity delivered is minimized by the curtain coating heads. The curtain coating heads (1a,1b) are displaced to the side of the web (w). An independent claim is included for the coating device.
