VORRICHTUNG UND VERFAHREN ZUR HERSTELLUNG VON DRAHT UND AEHNLICHEN LAENGLICHEN ELEMENTEN UND DAMIT HERGESTELLTER DRAHT.

摘要

An apparatus and method used in making wire and similar elongate members, and wire made using same, are provided wherein rods are extruded using a filled billet technique which comprises disposing the rods (44) in a can (40) comprising the filled billet and additional steps are employed which comprise placing the rods (44) in adjoining side-by-side relation to define a geometric pattern and fixing together at their ends those rods (44) defining the periphery of the pattern to define a dense pack (45) of the rods (44) wherein the placing and fixing steps are achieved prior to the step of disposing the rods within the can (40), and wherein the dense pack (45) and hence the rods (44) are adapted to fit snugly within the can (40) during the disposing step and separable filler means (46) is added between and around the rods (44) whereby the fixing step assures that during extrusion the rods (44) are reduced in cross-sectional area in a better controlled manner. An apparatus and method used in removing the can (40) from around the extruded rods (44) are also provided together with an apparatus (133) and method for separating the extruded rods.
