Abstract:
1. A method of producing a sandwich element comprising a lower and an upper skin, a frame joining the skins in an outer portion and a foam between the skins and within the frame comprising the steps of: applying said foam from a discharge orifice of an applicator into a cassette open to the top, comprising said lower skin and said frame, said cassette then being joined to said upper skin, thereby conveying said cassette by a conveyor means in a longitudinal direction and moving said applicator with said discharge orifice so that said foam is distributed in a transverse direction, wherein said applicator with said discharge orifice is moved two-dimensionally, one direction corresponding to said direction of transverse movement and the other direction corresponding to a direction of longitudinal movement in order to optimize a two-dimensional distribution of said foam within said cassette in that said foam application follows said two-dimensional movement of said discharge orifice.
