Abstract
A method and apparatus for forming a cast metal ribbon with a slit along the ribbon length includes the step of or a means for generating a controlled disturbance of the cast ribbon along a defined and localized width. The disturbance may be generated by a highly defined, needle-sized stream of gaseous media into the ribbon prior to complete solidification, or alternatively, a needle-like ceramic stylus. The dynamic pressure of the gaseous media or depth of stylus may be adjusted to completely penetrate the ribbon, severing the ribbon into multiple ribbons in a single casting; or alternatively, to only partially penetrate the ribbon, forming a score line of weakening and producing multiple ribbons readily detachable from each other along adjoining edges.
