The flange part 11c of one side, the flange part 11a of a side of the core 11 is incorporated in the recess 21a (Fig. 3) of the upper end of winder 21.
Specifically, the nozzle moving mechanism 33 shown in Fig. 1 and Fig. 2 moves the rotary part 39 for being provided with nozzle 31
To the top of winder 21, and make the center of rotation of rotary part 39 consistent with the center of rotation of winder 21.Nozzle moving machine
Structure 33 in this condition declines rotary part 39, using the pressure arranged in the mode coaxial with the center of rotation of rotary part 39
Bar 22 presses the top of above-mentioned core 11.
Core 11 is arranged at by this way winder 21.Then, the flange part of above-mentioned the opposing party is pressed in depression bar 22
In the state of 11c, the reel portion 11b of the delivery port 31a and above-mentioned core 11 that are formed as hexahedral nozzle 31 is faced.
Secondly as shown in figure 8, thread-clamping device 53 is stored so that the wire rod 12 drawn from nozzle 31 is along being arranged at volume
Mode around the core 11 in portion 21 is moved.Store the movement of thread-clamping device 53 is carried out by Xu Xian travel mechanisms 54 (Fig. 1).
And, as shown in figure 9, while winding tool 18 rotates, nozzle 31 is with faster than the rotary speed of winder 21
2 times of rotary speed rotate to the direction of rotation identical direction with winding tool 18.As a result, the quilt in wire rod draws operation
The wire rod 12 of extraction is wound in by rollback to the core 11 arranged in the winder 21, and the wire rod 12 newly sent from nozzle 31
Core 11, forms α convolute coils 17.
The rotary part 39 for being provided with nozzle 31 is rotated using motor 32 (Fig. 1) so that the nozzle 31 rotates.Thus,
Nozzle 31 rotates around core 11.The direction of rotation phase of the direction that the nozzle 31 is turned round around core 11 and winder 21
Same and speed is 2 times of the rotary speed of winder 21.
Thus, the wire rod 12 newly sent from nozzle 31 with roll up from clamping device 53 to the direction shown in the solid arrow of Fig. 9
The wire rod 12 for returning is together while coiling is in core 11.Now, the opposing party of the wire rod 12 newly sent from nozzle 31 along core 11
Flange part 11b be sent, be partial to the flange part 11b of the opposing party and be wound in reel portion 11c.
On the other hand, winding tool 18 rotates by the motor 23 for being installed on pedestal 13 shown in Fig. 1.By drawing in wire rod
Derivative wire rod 12 is extremely set by rollback in the winder 21 away from the winder 21 to go out in operation to make storage thread-clamping device 53
The core 11 put.
If the rollback of reality starts, Ze Xu lines travel mechanism 54 is with roughly equal by the speed of the wire rod 12 of rollback with this
Speed makes the close winder 21 of clamping device 53.Thus, wire rod 12 will not bend between clamping device 53 and core 11, can
The coil of the side in α convolute coils 17 obtained by preventing is bloated.
Now, helical spring 60 (Fig. 6) exerts a force to the storage thread-clamping device 53 to the direction away from winding tool 18, absorbs
Between the amount of the wire rod 12 by rollback and the amount of movement of clamping device 53 produce error, be reliably prevented clamping device 53 with
The bending of the wire rod 12 between core 11.Now, flange of the wire rod 12 for being held by clamping device 53 along a side of core 11
Portion 11a is wound in reel portion 11c by rollback to reel portion 11c, the flange part 11a along a side.
Thus, α convolute coils 17 are formed.The wire rod 12a at winding top and the wire rod 12b both sides of winding terminal are respectively positioned on
The most peripheral (Fig. 9) of α convolute coils 17.The wire rod 12a at winding top be it is in the wire rod 12 drawn in advance by clamping device 53,
