In the present embodiment, board member 55 is the both sides that are configured in hook 51, but the present invention is not limited to this mode, for example, also can be configured in 55 of board members a side of hook 51.In a word, as long as the structure of board member can eject wire rod 9 by rotation, frame mode in any case can.

The following describes its effect.

When beginning to carry out winding operation, with cartridge device 39 end of wire rod 9 is kept also being fixed earlier, this wire rod 9 is to extract out from the nozzle 21 of wire rod feedway 20 front ends.In this state, make wire rod feedway 20 import and make it to descend, the wire rod 9 from nozzle 21 extractions of wire rod feedway 20 front ends is wound up into 4 li of the slits of bobbin 1 inner peripheral surface as illustrated in fig. 4 from the major diameter peristome 2 of bobbin 1.

At this moment, the rotation of nozzle support 23 is freely, thus, as illustrated in fig. 4, the extraction end of nozzle 21 is naturally towards the top, by a plurality of belt pulleys 22 that are arranged on the wire rod feedway 20, wire rod 9 is depicted mild curve from wire rod feedway body 20A on one side to hanging on the nozzle support 23, on one side wire rod 9 is guided, make the angle of wire rod 9 roughly change 180 degree and from the extraction end non-resistance ground extraction of nozzle 21.Like this, between the extraction end of wire rod 9 and nozzle 21, can not produce excessive frictional force, can not make the tension force of wire rod 9 too high yet.

Because in the online material feeding devices 20 of wire rod 9, on one side that it is gently crooked by pulley 22, on one side it is guided, so the tension force of wire rod 9 is improved.

As shown in Figure 5, when nozzle 21 is directed into the position of passing small-diameter opening part 3, just make gear 25 engagements on combination member 26 and nozzle support 23 cardinal extremities, with the fixed angle of nozzle support 23 at that time angle.The hook 51 of downside hook device 50 is moved, and the hook-type leading section 51A with hook 51 catches on wire rod 9 as illustrated in fig. 6.

Hook 51 is risen, with wire rod 9 by fastening between the sheet 5, and with its guiding circumferential groove 6.Then as shown in Figure 8, by making bobbin 1 rotation, wind the line along circumferential groove 6; What then, make that hook 51 moves to that wire rod 9 will pass through fastens top between the sheet 5.At this moment make hook 51 hook-type leading section 51A towards changing over and the opposite direction of bobbin 1 sense of rotation, wire rod 9 is not come off from hook 51.

Like this, after directing on the circumferential groove 6, make hook 51 revolution as illustrated in fig. 9 to wire rod 9, the hook-type that makes leading section 51A up.Then as shown in figure 10, make board member 55 revolutions, with wire rod 9 tops upward, releasing wire rod 9 combines with hook 51, like this, just wire rod 9 is discharged, and just wire rod 9 can not be draged the residence by hook 51 thus and correctly direct into fastening between the sheet 5 of below, off-position.

Like this, after coiling finishes on the small-diameter opening part 3, make wire rod feedway 20 rise to major diameter peristome 2 once more as illustrated in fig. 11, simultaneously wire rod 9 is wound up into 4 li of slits.At this moment make the rotation of nozzle support 23 become free state again, thus, nozzle support 23 is extracted wire rod 9 out naturally down smoothly from nozzle 21, do not have unnecessary tension force fully and act on the wire rod 9.

As shown in figure 12, nozzle 21 arrive at major diameter peristome 2 above after, under this state with the fixed angle of nozzle support 23.Catch on wire rod 9 ground by hook 41 as illustrated in fig. 13 then and guided, wire rod 9 is directed into fasten between the sheet 7.

Under this state, make bobbin 1 time rotational as illustrated in fig. 14, just wire rod 9 is reeled along circumferential groove 8, then wire rod 9 is directed into fastening between the sheet 7 of will passing through.At this moment, wire rod 9 natures discharge from the hook 41 that is in wire rod 9 tops.After this as shown in figure 16, wire rod feedway 20 is directed in the interior week of bobbin 1 once more, repeat Fig. 4～coiling program shown in Figure 15.

As mentioned above, if use the present invention, because when wire rod 9 being wound up into 4 li of slits, the extraction end of nozzle 21 can freely turn round, thereby nozzle 21 tends to the resistance angle with smallest naturally, frictional force can be not excessive between nozzle 21 and wire rod 9, do not have excessive tension force fully on the wire rod 9 at coiling privileged site place.

Again because the angle of the extraction end of nozzle 21 can be fixed by gear 25 and combination member 26, so on the major diameter peristome 2 or small-diameter opening part 3 of bobbin 1, fastening between

sheet

5 or 7 and when winding the line on

circumferential groove

6 or 8, wire rod can be stablized from the extraction of nozzle 21, can correctly carry out winding operation.

Because the board member 55 that can freely rotate is set in hook 51 sides of carrying out winding operation, can eject and discharging colluding wire rod 9 on hook 51 on the small-diameter opening part 3, thereby can be when discharging wire rod 9 draged on hook 51 and fully can wire rod 9 correctly be put on the position of regulation occurrence positions skew ground.

Like this,, just can correctly be wound up into wire rod 9 on the position of regulation coiling of bobbin 1, can improve the shape and the feature accuracy of made deflecting coil if adopt the present invention.

Figure 17 represents an alternative embodiment of the invention.
