supplying the horizontally flowing stream of molten metal to the molding zone where it is in contact with a curved section of the belts 10 and 12 passing about pulleys 14 and 18 serves to limit distortion and thereby maintain better thermal contact between the molten metal and each of the belts as well as improving the quality of the top and bottom surfaces of the cast strip in accordance with the preferred embodiment of the invention the casting apparatus of the invention includes a pair of cooling means 32 and 34 positioned opposite that portion of the endless belt in contact with the metal being cast in the molding gap between belts 10 and 12 the cooling means 32 and 34 thus serve to cool the belts 10 and 12 just after they pass over pulleys 16 and 20 respectively and before they come into contact with the molten metal in the most preferred embodiment as illustrated in fig1 and 2 the coolers 32 and 34 are positioned as shown on the return run of belts 10 and 12 respectively in that embodiment the cooling means 32 and 34 can be conventional cooling means such as fluid cooling nozzles positioned to spray a cooling fluid directly on the inside and or outside of belts 10 and 12 to cool the belts through their thicknesses in that preferred embodiment it is sometimes desirable to employ scratch brush means 36 and 38 which frictionally engage the endless belts 10 and 12 respectively as.
