Abstract
The apparatus utilizes twin casting drums and a cast-on site removed from a sump formed between the two drums. The apparatus forms a completely uniform continuous metal sheet without a molten center when the sheet emerges from between the casting drums. Complete solidification of the metal sheet does not take place on a single casting drum, allowing for sheeting of substantially greater thickness to be uniformly cast.
