ABSTRACT:
A strip of amorphous metal is separated into first and second strips by scribing a line in a surface of the strip, thus defining first and second parts of said strip located on opposite sides of said scribed line folding and moving said parts of the strip together along the scribed line in the direction which encloses the scribed line close enough to form a crease and then at least partly flattening the strip. The strip separates into the first and second strips as the flattening operation proceeds along the strip. The facing cut edges of the first and second strips are moved apart once they are separated. To extend the life of the scribing tool, the flattening step may be extended to include reversing the crease.
