ABSTRACT:
A bundle of hexagonal billets, each billet being coated with a shear transmitting medium, is extruded through one form of die having a plurality of hexagonal die apertures, to produce simultaneously a plurality of individual hexagonal wires. The bundle may be extruded through another form of die having a single die aperture with a transverse cross-section registering with the transverse cross-section of the bundle, to produce simultaneously a plurality of individual hexagonal wires. In each case, the billet material is advanced against and through the die by means of frictional or viscous drag force exerted along the surface of the billet material toward the die. The foregoing operations may also be applied to drawing.
