Abstract
A slitting apparatus for an amorphous metal strip employs a scribing tool to form a scribed line in a surface of the strip as it is transported past the scribing tool. The scribed strip is folded toward the scribed line and creased between mandrels. Then the crease is flattened out against a flattening surface, whereupon the strip cleanly separates into first and second strips. A separating device downstream of the flattening surface moves the newly separated edges apart. A functional relationship between at least some of the radius of the cutting edge of the scribing tool, the scribing force, the tension in the strip and the separating device is described and empirical methods for maintaining these elements with effective operating ranges are given.
