ABSTRACT:
A rotary casting machine with an improved translatable band comprising a rigid frame with a rotary casting wheel having a peripheral groove mounted on the frame, the band and the wheel being relatively moveable to move "damaged" surface areas of the band out of contact with the wheel and present "new" surface areas for molding purposes. An endless band frictionally engages a portion of the wheel, the band having a width greater than the width of the casting wheel. Guide rollers on the frame orient the band properly on the frame and into cooperation with the groove of the casting wheel so as to form a mold. A power source drives the casting wheel and the frictionally engaged endless band. A spout is provided for the addition of molten metal to the groove and band mold. A pusher is provided to adjustably translate the band laterally across the peripheral groove of the casting wheel. In the preferred embodiment, the guide rollers have a width substantially equal to the band width and are reciprocally mounted on the frame. An alternative embodiment provides fixed shaft guide rollers wider than the band and a reciprocation shaft on which the band guide is mounted. Thus, the guide wheels are fixed, and the band guide moves the band to effect lateral translation.
