Abstract
In a continuous molten metal casting apparatus of the wheel-band type, wherein an elongated endless metal band partially closes a groove inscribed about the periphery of the rotatable casting wheel, an apparatus to apply and maintain a fixed, determinable tension to the elongated, endless band. The tension apparatus of the present invention permits the use of greatly elongated casting bands, maintaining a tension thereon, even during electrical power or air pressure supply failure, to thus provide improved band life. The tension wheel is rotatably mounted upon a carriage which slides on a pair of bellows-enclosed shafts, the carriage riding on a plurality of ball bushings. A dual-action air cylinder, attached at one end to the carriage and the other to the tension mechanism frame, operatively tensions the band through the wheel and carriage assembly. A spring loaded pawl attached to the carriage is restrained from engagement with a frame mounted rack during normal operation, which pawl engages the rack to constrain release of band tension should the air supply fail during operation. The apparatus is of a configuration such that it may be used or retrofitted with a great many of the various wheel-band casting machine configurations of past and present manufacture.
