PURPOSE:To save energy for a work, and to elevate the rate of operation of a wire twisting machine, by installing a bobbin to which plural steel strands have been bundle-wound, in a flyer, drawing out and twisting these strands, and after that, winding them in the outside of the wire twisting machine. CONSTITUTION:A strand supplying bobbin 1 to which plural steel strands for constituting the same layer of a twisted wire structure have been boundle-wound is installed in a state that it has been held by a cradle 28, in a flyer 20 of a wire twisting machine 2. Subsequently, a parallel strand bundle 3 drawn out from the bobbin 1 is wound round a twist back flow preventing roller 6 by 1 piece each and more than once, respectively, through guide rollers 4, 5, and after that, is led into an end plate 7. The end plate 7 has a small hole placed so as to be similar to the twisted wire structure. Each strand is bundled, keeping a similar figure with the twisted wire strcuture by feeding it to a voice 8 through each small hole of this end plate 7, and at this stage, it is twisted by rotation of the flyer 20. Subsequently, this strand bundle is drawn out to the outside of the wire twisting machine 2 through guide rollers 9, 10, and is wound round to a winding bobbin 15 after prescribed twist has been given. |
