Abstract
A two wheel type continuous extrusion apparatus has two rotary wheels having grooves receiving covering material rods, a fixed shoe block arranged therebetween and an abutement receiving a core metal wire. Covering material inlet apertures are provided for communicating passage-ways receiving the covering material rods to a covering chamber for extruding the covering material on the core metal wire to manufacture a composite metal wire. The covering material inlet apertures are inclined relative to a line connecting rotary axes of the rotary wheels such that the covering chamber is positioned on the side of supplying of the covering material rods relative to the connecting line. Consequently, a constraining force for constraining a shoe block becomes small.
