摘要： A method for impregnating a flat, fibrous substrate penetrated by a low viscosity, fluid synthetic resin, the substrate web 1 being preheated by known device 2 and thereupon being made to pass over a friction roller 3 which is heated where called for and which is uniformly wetted at its surface 6 with the low viscosity, aqueous synthetic resin solution based on an aminoplastic resin, substantially a melamine resin 5 or based on a phenolformaldehyde resin 5' present in a bath, the low viscosity, aqueous synthetic resin solution being uniformly heated and at least part of it penetrating the surface of the substrate web 1, whereupon the substrate web 1 loaded with synthetic resin is fully impregnated in the bath 4. Next this substrate web soaked with synthetic resin is made to pass through a metering device 7 and a drying channel 8 wherein the solvents of the aqueous, synthetic resin solution absorbed by the substrate are extensively evaporated in a flow of hot air and thereupon this substrate is cut to size in cutting device 9 into flat pieces 10 and is stacked in stacking device 11. The composites 10 are suitable to manufacture decorative cover layers, industrial insulating materials and core-layers of decorative molded laminates.
