ABSTRACT OF DISCLOSURE This invention relates to a twisting equipment for electrically conductive bare wires with an improved capability of providing continuous length of evenly twisted wires which will find their uses in the manufacture of stranded conductor for communication cable, appliance wire, and for automobile wiring harness. It consists of two major twisting portions. In the first twisting portion, a supply- reel around whose barrel a plurality of element wires are wound, preferably in a parallel alignment in width-direction of the supply reel, is located within an orbit of rotation of a first flyer bow. The wires are twisted once by the full turn of the flyer bow around two main shafts which share a common axis of rotation. The semi-braded product is then introduced into the second twisting portion and the final braded bare wire product is taken on a take-up reel after an additional process of twisting within an orbit of another flyer bow. As the two twisting portions are located in an independent, but adjacent position, feed wires are twisted conjunctively providing higher degree of twists per unit lenght of the product. In the wire twist- ing equipment of the present invention, feed wires are wound around one common supply reel which is located within an orbit of rotation of the flyer bow, instead of feeding a plurality of supply reels corresponding to the number of wires to be twisted.
