ABSTRACT:
A method and apparatus are provided for continuously slitting amorphous ribbon into a strip without adversely affecting the unique electrical, mechanical and magnetic properties of the material. The method includes the steps of heating a localized zone to approximately the glass transformation temperature and substantially simultaneously indenting the ribbon. The combined heating and indenting force produces a clean, high quality cut edge along the strip. Preferably, the positive engaging force causing indentation is effective to plow softened material to form a crystallized ridge adjacent the cut edge. The ridge is easily removed by a rotating brush. The indenter roller preferably includes a substantially V-shaped peripheral edge to concentrate the heat and force against the ribbon. A control unit is employed to provide the optimum heat, force and speed of relative movement between the indenter and the ribbon.
