In the gusset 6, the rollers 3 and 4 have known processes for producing the aforementioned 45 at a distance d which corresponds to the thickness of the La plates to be formed in that initially the sand layer is impregnated. In this gusset runs from gniert and then this layer between two fabrics a transducer 7 a mixture 7 of filler, coating is introduced, which is impregnated by the approximately sand and synthetic resin, so that resin contained in the whale sand layer is impregnated . zen a laminate consisting of the plate layer 9 When the sand is sufficiently soaked with resin, 50 and the two glass fiber mats 1 and 2, the fabric layers are also, as the experience shows, the glass fiber mats 1 and 2 of the perfectly impregnated with resin, so that gusset 6 is impregnated together with the filler supplied during curing a solid bond between fiber-resin. The laminate lies on top of the layers and the middle layer is made. Carrying sheet S is on and is carried out via a heating plate 19. However, this process is carried out in practical pre-hardening, after which it is much more difficult and time-consuming to carry out it in the hardening furnace. This would already create a continuous path, as it is, according to its schematic representation, from which rigid cladding may appear. In the simplest form one can manure plates could be separated. The providence imagine the process in such a way that the first direction is used, but in this case a layer of fabric is applied to a film for production. Then 60 of plates with a decorative layer. For this purpose, the sand impregnated with resin is applied and a resin is applied by means of a device 12 to the second fabric layer, which is also applied to the laminate and which has to be covered with a film, since the formed receptacle 13 is grained mineral Matedete laminate in the usual way through a pair of rollers rial 14, for example granular limestone, must run through. The process steps 65 are brought about, which are pressed into the resin by a foam-covered roller 15 which does not pose any particular difficulty in itself, whereupon a curing oven 11 is integrated into the resin layer in the th, but because of its series connection.
