Abstract: The present invention comprises several embodiments of a continuous casting machine for uninterrupted continuous production of non-ferrous metals and alloys, the machine having a pair of endless flexible mold assemblies, including mold blocks abutting each other in end-to-end relationship and each having a mold channel in one face thereof, whereby coengaging straight sections of the assemblies of mold blocks form a continuous mold cavity, extending forward and downward from the inlet end at an angle to provide desirable flow levels at the inlet of the cavity, the length of mold blocks in one assembly being preferably half the length of the mold blocks in the other assembly and indexed so that the abutting faces of the blocks of one assembly occur intermediately of the blocks of the other assembly to prevent heat dams from occurring.
