Abstract:
1. An apparatus for re-shaping and stranding a plurality of formed wires each having a cross-sectional area, comprising: a bobbin holder for holding a plurality of bobbins wound with formed wires; a stranding head for receiving and guiding formed wires unwound from said bobbins; a stranding die for converging and consolidating said formed wires received from said stranding head: a reduction tube device between said bobbin holder and said stranding die, said device comprising a plurality of reduction tubes, one for each formed wire, said reduction tubes being interconnected by a plate and each being oriented to maintain a relatively straight path for the formed wire passing therethrough; said bobbin holder, stranding head and reduction tube device being rotatable relative to said stranding die to cause said formed wires to strand together when passing through said die; and wherein each said reduction tube has; a reservoir for containing lubricant having a first open end and a second open end in alignment with said first open end; a guide mechanism closing said first open end of the reservoir for guiding formed wire into said reservoir; and a wire shaping mechanism closing said second open end of the reservoir for shaping the formed wire when said formed wire is pulled therethrough, the wire shaping mechanism reducing the cross-sectional area of the wire by 24% at most.
