The invention relates to a method for producing sandwich panels comprising a metal skin plate, a core layer of foam material and, if desired, a cover plate, the metal skin plate being provided, in the longitudinal direction of the sandwich panel, with outwardly projecting profiling in the form of a number of furrows with a cross section which is substantially trapezium-shaped, the method comprising the following steps: a. the metal skin plate is positioned substantially horizontally, in such a manner that the furrows are open at the top; b. the furrows are filled with a first quantity of foaming agent, in such a manner that the furrows, after the foaming of the foaming agent, are substantially completely filled; c. after the foaming agent in the furrows has been substantially completely foamed, a second quantity of foaming agent is arranged above the metal skin plate in order to form the core layer by foaming; d. if desired, a cover plate is applied during or after the foaming of the core layer. The invention also relates to a device for carrying out the method and to a sandwich panel produced in this way. <IMAGE> |
