The pressure roller 21 moves together with the wire 13 by the rotation of the winding shaft 12.

Further, since tension is generated and applied to the wire 13 by the rotational friction of the pressure roller 21, the wire 13 can be wound around the winding shaft 12 without the tip 16 of the wire 13 coming off the groove 14.

Further, even when the outer diameter of the winding changes due to the lamination and winding of the wire 13, a constant pressing force can be continuously applied to the wire 13 by moving and following the lever 22. Laminated winding without looseness can be performed.

As shown in FIG. 4, when the winding accuracy is further improved, or when a wire 13 having a deformed shape or a wire 13 having a rectangular cross-section partly rounded by a curve is wound. By providing an inclined portion 32 at the tip of the pressure roller 31 toward a position away from the outer peripheral surface of the guide body 15, the guide body 15 is wound while the wire 13 is wound around the winding shaft 12.
A component force is generated in the direction, and the wire 13
Can be wound with the sides aligned. Also, as shown in FIG.
An annular winding guide 41 that abuts one side surface on the outer peripheral surface of the guide body 15 and guides the other side surface may be provided.

Hereinafter, a winding device according to another embodiment of the present invention will be described with reference to the drawings.

FIG. 6 is a perspective view of a main part of a winding device according to an embodiment of the present invention.

In FIG. 6, reference numeral 41 denotes a main body base made of a metal material or the like, and reference numeral 42 denotes a winding shaft rotatably provided on the main body base 41. A disk-shaped guide body 43 is mounted on the winding shaft 42, and regulates and guides one side surface of the wire 44 following the operation of the winding shaft 42.

Further, a rotatable pressure roller 45 is provided on the outer peripheral surface of the winding shaft 42, and the wire 44 is wound around the outer circumference of the winding shaft 42 while the wire 44 is pressed by the pressing roller 45. The pressure roller 45 is attached to one end of a lever 46 that is swingably or movably mounted on the main body base 41.

The other end of the lever 46 is movably connected to the tip of a cylinder 47. Driving force is supplied to the cylinder 47 and the winding shaft 42 from a winding driving mechanism (not shown in the figure) provided in the main body base 41, and each performs a predetermined operation.
