Patent ID: 8613981

Claim:
A process for the production of composites, comprising at least one outer layer and of an isocyanate-based rigid foam, where the outer layer is moved continuously and a liquid starting material for the isocyanate-based rigid foam is applied to the outer layer, which comprises achieving an application of the liquid starting material for the isocyanate-based rigid foam through at least one fixed tube which has openings and which has been placed, with respect to the outer layer, so as to be parallel to the plane of the outer layer and at right angles to the direction of movement, wherein the liquid starting material for the isocyanate-based rigid foam is fed from the middle of the tube, when there is one tube, and from the middle of each tube, when there is more than one tube, and the length of the openings decreases from the middle to the ends of the, or each, tube.
