ABSTRACT OF THE DISCLOSURE Groups of juxtaposed slot nozzles are subject to the action of the same or different melts for producing thin metal strips or foils with a considerable width. The melts are applied as a closed pool to a moving cooler surface, e.g. a rotating drum, where the pool is solidified to a closed metal strip. These groups, which are staggered in the direction of movement of the cooler surface, can be subject to the action of different melts, so that a metal strip is obtained with juxtaposed and sharply defined regions with different characteristics. It is possible to produce amorphous or mixed amorphous/crystalline, or solely crystalline material structures. Alter- natively, by producing different cooling capacities on different surface areas, or by different structuring of different surface areas, it is possible to influence the solidification process of the melt on the cooler surface in such a way that within the strips or foils obtained) there are adjacent regions having different metallic and/or geometrical structures. Through the geometrical configuration of the cooler surface, it is possible to produce foils with a structured surface or with shape-limited individual regions, which permits the mass production of small parts from sheet or strip material.
