<p>The invention relates to a device for applying liquid reaction mixtures to a cover layer, the cover layer being moved continuously and the liquid reaction mixture being applied to the cover layer, the device consisting of at least one pipe (a) which is preferably immovably arranged and which is provided with openings (b) in the direction of the cover layer, and which is mounted above the cover layer parallel to the cover layer plane and at a right angle to the direction of motion of the cover layer, the outer openings being located on the side of the pipe that is above the edge of the cover layer, at an angle of 1 to 50° in the direction of the edge of the cover layer. The invention further relates to the use of said device to produce composite elements and to apply liquid reaction mixtures to a cover layer. The invention further relates to a method for producing composite elements, comprising the application of liquid reaction mixtures to a cover layer by means of said device, the cover layer being moved continuously and the liquid reaction mixture being applied to the cover layer.</p> |
