Abstract
Abstract Juxtaposed nozzle openings apply the same or different melts to the surface of a moving cooler surface for producing thin metal strips or foils with a considerable width. The nozzle openings can be staggered in the direction of movement of the cooler surface and apply different materials to produce a metal strip with juxtaposed and sharply defined regions with different characteristics. Amorphous or mixed amorphous/crystalline, or solely crystalline material structures can also be produced. Alternatively, different cooling capacities on different cooler surface areas and different structuring of different cooler surface areas permit the melt to solidify on the cooler surface such that the strips or foils obtained have adjacent regions with different metallic and/or geometrical structures. By geometrical configuration of the cooler surface, foils with a structured surface or with shape-limited individual regions can be used for mass production of small parts from sheet or strip material.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
133 words
An apparatus for forming strip-like or foil-like products from metallic material or metallic oxide material, comprising: at least one storage container means for supplying metallic or metallic oxide melt; a cooler surface movable at a regulated speed; and a plurality of laterally juxtaposed and overlapping nozzle openings coupled to said storage container means and oriented relative to said cooler surface such that action ranges of said nozzle openings overlap one another on the cooler surface, and such that melts from said nozzle openings combine into a closed melt upon contacting said cooler surface, which closed melt is solidified upon combining of the melt from each of said nozzle openings producing a product of uniform metallurgical quality over an entire width thereof, the width being greater than that of each of said nozzle openings.
Claim 2
Independent Claim
133 words
An apparatus for forming strip-like or foil-like products from metallic material or metallic oxide material, comprising: at least one storage container means for supplying metallic or metallic oxide melt; a cooler surface movable at a regulated speed; and a plurality of laterally juxtaposed and overlapping nozzle openings coupled to said storage container means and oriented relative to said cooler surface such that action ranges of said nozzle openings overlap one another on the cooler surface, and such that melts from said nozzle openings combine into a closed melt upon contacting said cooler surface, which closed melt is solidified upon combining of the melt from each of said nozzle openings producing a product of uniform metallurgical quality over an entire width thereof, the width being greater than that of each of said nozzle openings.
