    Abstract: A wire is pulled by squeeze rolls through a drawing die, a guide bushing, a circumferential milling device, and an axially operative shaving die. The shaving die forms a virgin surface on the wire. The milling device is operative closely adjacent to the inlet of the shaving die so as to cut away its chips and prevent jamming thereby and wire breakage. Between the shaving die and the draw rolls clean cladding strips are brought into engagement with the virgin surface of the wire to effect solid-phase bonding thereto under roll squeezing action. They converge in a compartment leading to the rolls and containing a protective or reducing atmosphere. The cutting edge of the shaving die also forms a gas seal around the wire inlet to this compartment.

    Abstract: Apparatus for solid-phase metallurgically bonding metal cladding materials such as copper to a wirelike core of aluminum or the like is shown to include means such as an annular shaving die for cutting metal materials from the entire periphery of the wirelike core to expose a virgin metal surface therearound, means such as a manifold establishing a protective or oxide-reducing atmosphere around the virgin metal core surface for maintaining the virgin metal surface free of bond deterrents, means direction clean metal cladding materials around the virgin metal core surface, and means such as a pair of peripherally grooved rolls squeezing the cladding material against said virgin metal core surface with reduction in the composite thickness of the core and cladding material for bonding the cladding to the core entirely around the periphery of the core.

    Abstract: A BATH OF ALUMINUM IS MAINTAINED AT CERTAIN DEPTHS LESS THAN APPROXIMATELY 2 1/2 INCHES. AT A GIVEN DEPTH BELOW 2 1/2 INCHES A STEEL CORE WIRE IS CONTINUOUSLY MOVED UP VERTICALLY THROUGH THE BATH. THE TEMPERATURE OF THE CORE WIRE AND THAT OF THE BATH AFFECT THE AMOUNT OF ALUMINUM THAT IS RETAINED BY FREEZING ON THE CORE INDEPENDENTLY OF A SUBSTANTIAL RANGE OR WIRE SPEEDS. AT A GIVEN BATH DEPTH LESS THAN 2 1/2 INCHES THE PERCENTAGE OF WEIGHT OF ALUMINUM COATING CLINGING TO THE STEEL CORE MAY BE ADJUSTED SIMPLY BY VARYING THEIR RELATIVE TEMPERATURES.
