As shown in the figure, a coil 30 that has been previously wound and shaped externally by a method such as self-fusion is deformed and inserted into the inner periphery of the core 24, and then inserted into the winding groove. A forming method has been adopted in which the coil is shaped again within the coil. However, with this forming method, there are many steps such as winding, shaping, deformation, insertion, and reshaping, and it is extremely difficult to reshape the coil once it has been deformed so that it fits within the groove of the core. There were many malformations.

５を規制する様にしている。 To wind the core 1 in this manner, first, as shown in FIG. 2, an adhesive 13 diluted with a solvent is applied to the winding groove 2 from the application nozzle 12. After the diluted adhesive 13 is applied, the solvent evaporates and the adhesive 4 becomes an adhesive film. This adhesive 4 is used in adhesive tapes and the like, and is called an adhesive or a pressure-sensitive adhesive. Next, the wire 5 is wound in the winding groove 2 whose bottom surface is coated with the adhesive 4. FIG. 3 shows the state before the start of winding, in which the wire supply nozzle 6 that supplies the wire 5 into the winding groove 2 is located directly above the vertical groove 3, and the wire 5 is
is pulled out from the wire supply nozzle 6 along the longitudinal groove 3, and its tip is fixed externally (not shown) by a suitable method such as soldering, wrapping, chuck, etc. A pressure roller 7 is made of a material to which the adhesive 4 does not adhere, for example, tetrafluoroethylene, and escapes from the winding groove 2 before winding starts. That is, the line supply nozzle 6 is provided on a flange 9 attached to the tip of a hollow rotating shaft 8, and the line supply nozzle 6 is press-contacted to the tip of a lever 10 attached to a fulcrum shaft 11 rotatably supported by the flange 9. A roller 7 is rotatably mounted, and before winding starts, the rotating shaft 8 is eccentrically positioned so that the wire supply nozzle 6 does not interfere with the core 1, and the pressure roller 7 escapes from the winding groove 2. The fulcrum shaft 11 is retracted and rotated. Next, when the winding operation begins,
As shown in FIG. 1, the rotating shaft 8 moves to the same axial position as the core 1 and rotates within the core 1 while supplying the wire 5 from the wire supply nozzle 6, and the wire 5 is transferred to the winding groove 2. supplied within. Further, the pressure contact roller 7 is urged toward the bottom surface of the winding groove 2 via the lever 10 by rotation of the fulcrum shaft 11 in a clockwise direction, and the pressure roller 7 is forced to press the wire rod 5 that is supplied to the bonded wire 5. Agent 4
Press and secure with adhesive. Once the winding is complete,
Returning to the positional relationship as shown in FIG. 3, the entire unit comes out of the core 1 while drawing out the wire 5 from the wire supply nozzle 6. Although not shown,
Actually, at this time, when the wire 5 bends 90 degrees from the winding groove 2 and moves to the vertical groove 3, the wire 5 is regulated so that it does not come off the groove.

Reference numeral 14 denotes another flange provided on the rotating shaft 8, which rotatably supports the other end of the fulcrum shaft 11 and supports a second lever 15 attached to the fulcrum shaft 11.
A tension spring 16 is interposed between the flange 14 and the flange 14 to urge the support shaft 11 to rotate clockwise.
17, when the rotating shaft 8 is at the origin position shown in FIG.
This is an air cylinder that rotates counterclockwise against the urging force of the fulcrum shaft 11 to retract and rotate it. 1
8 is a spur gear attached to the rotating shaft 8 and transmits the rotational force of the drive motor 19 to the rotating shaft 8. 20
is a boppin around which a wire 5 is wound, and the wire 5 is supplied from this boppin 20 through the hollow rotating shaft 8 to the wire supply nozzle 16. Reference numeral 21 denotes a feeding table that moves the unit forward and backward, and moves the tip of the wire supply nozzle 6 to a predetermined position of the winding groove 2.
Carry out traverse through the winding. Reference numeral 22 denotes a feed table that moves the unit up and down, and serves to lower the wire supply nozzle 6 and the pressure roller 7 into the wire winding groove 2 and release it out of the groove. 23 is a bracket to which the rotating shaft 8, the drive motor 19, and the air cylinder 17 are attached.

Similarly, the same effect can be obtained by moving the line supply nozzle and the entire unit up and down and back and forth by moving the core 1 in opposite directions with the same stroke. Furthermore, the mechanism shown in Fig. 4 is an example, and its driving method and transmission method are not limited to this, and the key points are the rotation of the wire supply nozzle, the vertical and back-and-forth movements, and the pressure roller's movement. Any configuration may be used as long as rocking motion is possible.

For,
Since the wire is moved relatively parallel to the central axis and is wound while pressing against the contact agent, the wire is aligned in the winding groove, and the wire is of high quality without lifting. A coil is obtained. In addition, since the wire is wound directly on the inner surface of the cylindrical shape, the number of processes is significantly reduced compared to the conventional forming method.
This has a huge effect in terms of productivity.
