ABSTRACT:
A method and apparatus is presented for the manufacture of brittle wire by the co-extrusion, or filled billet method. The invention involves a step by step method by which a billet can is specially prepared with a chamfered front end and a concave, collapsible front plate and a uniquely vented rear end. The result is a superior process in which bursting of the can and front end is eliminated, thereby resulting in a superior product, increased yield, improved safety and the like.
