Abstract: The invention relates to a method for producing a sandwich panel made of at least one cover layer (26, 28) to be laminated and at least one core layer material block (8, 8?, 10, 10?, 12, 12?, 14, 14?), characterized by the step of: arranging a core layer material block and a transverse beam (4, 16, 18) made of a previously laminated panel, such that a surface of the core layer material block and an edge of the transverse beam form an area that can be jointly laminated for the cover layer to be laminated and such that the transverse beam is at an angle to the area that can be laminated, and by the following step: laminating the area that can be laminated, so that resin produces a bond between the surface of the core layer material block and the edge of the transverse beam on one side and the cover layer to be laminated on the other side.
