The hooks 1 and 2 are configured to be able to enter and exit from the tips of the nozzles 3 and 4, and the nozzles 3 and 4 are connected to suction means for sucking the conducting wire 5 hooked by the hooks 1 and 2 into the inside. The conducting wire 5 is first wound on a take-up reel (not shown), cut out after being drawn out by a certain length, and one end side is gripped by a gripping means 10.

A description will be given of a winding method using the winding apparatus configured as described above. First, in a state where a pair of magnetic heads 8 are fixed to a jig 7 on the table 6, the gripping is performed in parallel with the magnetic heads 8. The conductor 5 is pulled out from the take-up reel by a certain length while the one end is gripped by the means 10. At this time, one of the nozzles 3 and the hook 1 are on standby according to the height of the groove 9 between the pair of magnetic heads 8, and the height of the conducting wire 5 on the side of the magnetic head 8 is slightly smaller than the height of the hook 1. (See FIG. 1).

In this state, the hook 1 is made to protrude from the tip of the one nozzle 3, and the tip of the hook 1 is positioned below the conducting wire 5 through the groove 9 between the pair of magnetic heads 8.

In this state, the hook 1 causes the nozzle 3
The conducting wire 5 drawn into the inside is further drawn in by the suction of the suction means by air. As a result, the other end of the conductive wire 5 is drawn into the nozzle 3, and then the table 6 is moved in the direction of arrow A from the position facing the hook 1. More specifically, the other nozzle set so that the conducting wire 5 is substantially linear between one end and the tip of the nozzle 3 while the conducting wire 5 passes through the groove 9 between the pair of magnetic heads 8. The table 6 is stopped at the positions of the hook 4 and the hook 2 (see FIG. 4).

It is positioned on the lower side, and in this state, the gripping means 10 is lowered to pull down one end of the conductive wire 5,
The conductor 5 is placed on the hook 1 (see FIG. 7).

Next, the hook 2 is moved into the nozzle 4 to draw the other end of the wire 5 into the nozzle 4, and the other end of the wire 5 drawn into the nozzle 4 is further drawn to the suction means. (Figure 8)
reference).

Thereafter, the table 6 is moved in the direction of arrow B opposite to the direction of arrow A to stop the table 6 at the position of one of the nozzles 3 and the hook 1 (see FIG. 9). Then, at the position shown in FIG.

In this state, the hook 1 is made to protrude from the tip of the one nozzle 3, and the tip of the hook 1 passes through the groove 9 between the pair of magnetic heads 8 and is lifted by the other nozzle 4. It is positioned on the lower side, and in this state, the gripping means 10 is lowered to pull down one end of the conductive wire 5,
The conductor 5 is placed on the hook 1 (see FIG. 12).

Next, the hook 1 is moved into the nozzle 3 to draw the other end of the conducting wire 5 into the nozzle 3, and the conducting wire 5 is further pulled in by the suction means using air, as shown in FIG. The same operation as described above is repeated from the state.

By repeating such an operation, winding of one of the pair of magnetic heads 8 is performed. Note that this winding is formed by a close alignment winding from the lower side of one magnetic head 8. In order to perform such a close alignment winding, the table 6 is raised by the thickness of the conductive wire 5 for each turn.

By the way, after the winding of the other magnetic head 8 is completed, the winding of the other magnetic head 8 is completed. It can be performed in the same manner as the winding.

The first embodiment in which the winding is performed while rotating the table 6 has been described above.
The winding can be performed without rotating the table 6 as in the second embodiment shown in FIG.

The winding method according to the second embodiment shown in FIGS. 13 to 20 will be described below. The description of the winding method of the second embodiment will be started from the state shown in FIG. 13, but the state before this state is the state shown in FIG. 4 described in the winding method of the first embodiment. And the description is omitted.

The one of the nozzles 3 and the hook 1 are raised from the state shown in FIG. 4 to incline the conducting wire 5 between the pair of magnetic heads 8 and the tip of the one nozzle 3 (see FIG. 13). In this state, the hook 2 is projected from the tip of the other nozzle 4 and the tip of the hook 2 is
(See FIG. 14), and in this state, the one nozzle 3 is lowered to move the conductive wire 5 between the magnetic head 8 and the tip of the one nozzle 3 to the other nozzle. 4 is placed on the hook 2 protruding from the tip of FIG.
reference).

Thereafter, the hook 2 is moved into the other nozzle 4 to draw the other end of the conductive wire 5 into the nozzle 4, and the conductive wire 5 is further drawn by the suction means using air. As a result, the other end of the conductive wire 5 is connected to the nozzle 4
(See FIG. 16).

Thereafter, the table 6 is moved in the direction of arrow B opposite to the direction of arrow A to stop the table 6 at the position of one of the nozzles 3 and the hook 1 (see FIG. 17). From this state, the other nozzle 4 and the hook 2 are raised to incline the conducting wire 5 between the pair of magnetic heads 8 and the tip of the other nozzle 4, and the hook 1 is moved from the tip of the one nozzle 3.
And the tip of the hook 1 is connected to the pair of magnetic heads 8.
It passes through the upper side of the conductive wire 5 between the one end side gripped by the gripping means 10 and the pair of magnetic heads 8 in the groove 9 between and is positioned below the conductive wire 5 lifted by the other nozzle 4. In this state, the other nozzle 4 is lowered and the conductive wire 5 between the magnetic head 8 and the tip of the other nozzle 4 is placed on the hook 1 projecting from the tip of the one nozzle 3 (see FIG. 18). 19).

Thereafter, the hook 1 is moved into one of the nozzles 3 to draw the other end of the conductive wire 5 into the nozzle 3, and the conductive wire 5 is further drawn by the suction means using air. As a result, the other end of the conductive wire 5 is connected to the nozzle 3
(See FIG. 20).

By repeating such an operation, winding of one of the pair of magnetic heads 8 is performed. It should be noted that this winding is such that the table 6 is raised by the thickness of the conducting wire 5 for each winding so that the close-aligned winding is performed from below the one magnetic head 8. This is the same as the first embodiment.

After the winding for the other magnetic head 8 is completed, the winding for the other magnetic head 8 is completed by using the conductive wire 5 of the remaining half length continuing from the one magnetic head 8. It can be performed in the same manner as the winding.

By the way, the present invention uses one or both of the two winding methods described above for winding a magnetic head other than the magnetic head 8 of the embodiment shown in the drawings. Can be performed. Furthermore, in the above two embodiments, the conductor 5 is hung from above the hooks 1 and 2, but the conductor 5 may be hung from below the hooks 1 and 2.
