Description of the Related Art Recently, electric wires used in IT-related computers, such as electric wires connecting a board of a notebook type personal computer and a liquid crystal display, and mobile phones have been used. The wire used for such wire has been thinned to a diameter of 30 μm or less.
Ultra-fine wires of more than 10 μm have been used. [0003] By the way, in the conventional double twisting assembly machine, a stranded wire winding bobbin having a relatively large flange diameter, that is, a large bobbin is mounted on a cradle. For this reason, the rotating diameter of the arched flyer that can be rotated around the cradle must be increased, but in the case of a stranded wire with a low allowable tension such as a very fine wire, due to the centrifugal force and wind pressure generated in the arched flyer, Because line elongation and disconnection occur,
It was not possible to increase the number of revolutions of the twice twisting assembly machine. It is an object of the present invention to provide a two-twisting assembling machine capable of reducing the rotating diameter of an arched flyer as compared with a conventional one. [0005] In general, a copper alloy is used for an ultrafine wire, so that the wire is hard and brittle. However, in a conventional twice-twisting assembly machine, a reverse twist that cancels out the twist of the wire that occurs during twisting. Is not applied to the strand in advance, so that the wire frequently breaks when twisted. Further, the twisted wire may be twisted. When twisting such an ultrafine wire, a tubular twisting machine having a twist is generally used. This is because there is no twisting in the twice twisting assembly machine. Therefore, when twisting back with a double twisting machine,
Since the rotary element feeding device is used outside the main body of the two-twisting assembly machine, a large space is required as a whole, and power is required for both, so that the amount of electricity used inevitably increases. Another object of the present invention is to provide a double twisting assembly machine which does not require a rotating wire supply device outside the main body. [0007] According to the first aspect of the present invention, 2
