The present invention relates to a wire
bunching machine, and more particularly to the wire
stranding machine capable of stranding wires evenly.
According to the prior art, the capstan is located inside the rotary
structure and just in front of the winding drum, and the wire material is being
stranded as well as given a tension at the time of passing through the flyer
bow. But because of the long distance between the wire supply position and the
capstan, there may cause an irregular pitch in stranding the wires thereby
resulting in an unevenly stranded product even if the wires were pulled with a
given tension.
A Wire
stranding machine comprising a plurality of stands, each
carrying a pair of bobbins disposed on opposite sides of the stand, wire on a
bobbin being fed through a hollow, rotatable shaft on the stand along with a
core, such as an electric cable core, and to a stranding unit. The number of
stands is equal to the number of wires to be stranded, and each stand carries
means for paying-off wire from either bobbin and means for loading either bobbin
with wire, the wire guiding means of the latter being movable from adjacent one
bobbin to adjacent the other bobbin, whereby one bobbin may supply the wire for
stranding while the other bobbin is being loaded with wire. Drive means,
separate from means which rotates the hollow shaft, rotates the bobbin being
loaded and can drive either bobbin.
