It is freely inserted and inserted, and a wire guide for hooking the thread on the thread guide is provided at the tip of the shifter, and the thread guide is arranged to rotate on the thread guides of the primary heaters on both sides of the shifter. It is an inexpensive device that ensures that the yarn can be hung on the top of the heater.

[0009]

[Action]

 Since the present invention is configured as described above, when threading on the heater, the shifter is rotated in the shifter guide so that the wire guide at the tip of the shifter is directed to the heater side adjacent to one side of the shifter guide. Hang the thread on the thread and lift it up, hook the thread on the thread guide fixed to the upper part, and then lower the shifter. Next, the shifter is rotated 180 degrees, the wire guide is directed to the heater side adjacent to the other side of the shifter guide, and similarly, the thread is hooked on the wire guide and lifted up, and the thread is hooked on the thread guide on the heater and lowered. At this time, the wire guide is hooked and supported by the upper end of the shifter guide. In this way, by operating one shifter provided for every two heaters in the same manner, threads are applied to all the heaters and the false twisting machine is operated to perform false twisting.

【Example】

 Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a drawing false twisting machine. Each weight of the drawing false twisting machine has an upstream feed roller 2 supported by a creel stand 1, a primary heater 3, a balloon control plate 4, a false twisting device 5, A downstream feed roller 6, a secondary heater 7, a second downstream feed roller 8, and a winding device 9 are provided. In this draw false twisting machine, a large number of weights having the above configuration are arranged in parallel.

Each yarn Y drawn from the plurality of yarn supplying packages P1 supported by the creel stand 1 is introduced into each primary heater 3 from each upstream feed roller 2. The yarn discharged from the primary heater 3 enters each belt type false twisting device 5 via the balloon control plate 4, and further passes through each downstream feed roller 6, each secondary heater 7, and the second downstream feed roller 8. It is wound on the winding package P by each winding device 9. The twist imparted by the false twisting device 5 tries to propagate to the upstream feed roller 2, and the twist is thermally fixed by the primary heater 3. The primary heater 3 has a tubular body 22 curved in an arch shape in a heat insulating cover 21 with an opening / closing lid, and has a thread running portion 17 which is a recess on the outer surface of the tubular body 22 on the curved side. is doing.

A large number of primary heaters 3 of the draw false twisting machine are arranged upright in parallel according to the number of weights, are tall, and it is difficult to hang the yarn at the time of starting.
