Abstract
A method and apparatus for parting a deck of amorphous alloy ribbons in one operation is disclosed. Force is applied to a deck of ribbons to place it under tension. A localized zone in the deck is compressed and rapidly heated to the softening temperature of the amorphous alloy. The deck separates along a seam within the zone due to the tensile force and localized rapid heating. A high quality edge is produced where the separated ribbon edges are free of burrs, meltbeads or substantial cracking and chipping.
