Abstract: The invention comprises a tool turret for a turning machine whose operational axis has a wider spacing from the bed of the carriage than the spindle axis of the turning machine. The tool turret has an inner rim with inner turning tools and an outer rim with outer turning tools, the inner and outer turning tools being angularly offset in relation to each other. In order to bring the inner and outer turning tools into operating position during the stepwise further movement of the turret, successive operational angles must be variable. Because of the wider spacing of the operational axis from the bed of the carriage, the turret disc carrying the tools can be made larger with the result that more tools can be provided thereon or the spacing between the tools can be enlarged. The changeover with unequal angles can be accomplished by means of a regulated direct current motor, the operational angle being fed into the regulation circuit as the desired value.

Abstract: A method of and apparatus for continuously casting molten metal are disclosed wherein the flexible band element used to enclose the peripheral groove of the casting wheel of a wheel-band type machine is relatively untensioned and supported along at least a portion of its path of travel by a highly flexible porous support belt through which a coolant may be directed to impinge upon the external surface of the flexible band. The flexible band element, in cooperation with the support belt, provides improved cooling efficiency and a longer life expectancy for the band.
