Method and device for producing a sandwich board

The method for producing a sandwich board having a core layer or a middle layer (14) arranged between two cover layers, comprises fixedly connecting the core- or middle layer with the cover layers, where the middle layer is area-wisely formed in such a way that the middle layer forms a defined cavity structure between the both cover layers, applying and/or inserting the middle layer in a workpiece reception device (4), subsequently coating the middle layer with adhesive at both sides in defined middle layer areas in a flat manner, and feeding the coated middle layer to a pressing device (5). The method for producing a sandwich board having a core layer or a middle layer (14) arranged between two cover layers, comprises fixedly connecting the core- or middle layer with the cover layers, where the middle layer is area-wisely formed in such a way that the middle layer forms a defined cavity structure between the both cover layers, applying and/or inserting the middle layer in a workpiece reception device (4), subsequently coating the middle layer with adhesive at both sides in defined middle layer areas in a flat manner, and feeding the coated middle layer to a pressing device (5) by using a transferring device (10), where the both cover layers are simultaneously connected and/or pressed with the middle layer in the pressing device. The middle layer is coated with adhesive by using an adhesive coating roller device (6) having a coating roller. The adhesive coating roller device has a spin spraying nozzle in addition to the coating roller. The middle layer is section-wisely sprayed with adhesive along a defined outer circumferential edge area by using the spin spraying nozzle. The adhesive is applied with the coating roller at the middle layer area inwardly subsequent to the circumferential edge area. The middle layer is turned around 180[deg] in the workpiece reception device after coating a first middle layer side. The second middle layer side is coated with adhesive in defined middle layer areas. The already coated middle layer side is subjected with heat by using a heating device after turning in the workpiece reception device in such a way that the first adhesive layer applied on the middle layer is heated at a defined temperature of larger than 80[deg] C. The coating roller is contour-adapted by using a control device and/or a regulating device and/or is processed in any space directions along the middle layer side to be coated in such a way that it has
