However, in the present invention, the support of the clamping force adjusting member C is required. By adjusting the position of the pin c2, the clamping force of the yarn t by the solid wax w and the rotary disk 7 can be adjusted, so that the adjustment can be performed easily and quickly, and Support pin c
Since the position of 2 can be finely adjusted, therefore,
Fine adjustment of the clamping force is possible. As described above, since the clamping force of the yarn t by the solid wax w and the rotary disk 7 can be performed by the clamping force adjusting member C without adjusting the pressing force of the pressing member 14, the pressing member 1
The control and adjustment of the pressing force of 4 can be simplified. It is preferable that the solid wax w and the rotating disk 7 are forcedly rotated, but they may be configured to be rotated by running the yarn. Alternatively, it may be fixed.

[0026]

Since the present invention is configured as described above, it has the following effects.

Since the wax unevenness due to the yarn unevenness can be prevented, and the clamping force of the thread between the solid wax and the wax pressing member is adjusted by the clamping force adjusting member according to the thickness of the thread and the like. It is possible to prevent the yarn from being cut.

Since the clamping force of the yarn between the solid wax and the wax pressing member can be performed by the clamping force adjusting member without adjusting the pressing force of the pressing means, the pressing force of the pressing means is controlled and adjusted. Can be simplified.

Since the wax adhering portion due to the thread clamping and the wax adhering portion due to the thread tension are provided, the wax can be sufficiently attached by the wax adhering due to the thread clamping, and the wax adhesion unevenness due to the thread irregularity due to the wax adhesion due to the thread tension. Can be prevented.

By adjusting the position of the support pin, the clamping force of the thread between the solid wax and the wax pressing member is adjusted, so that the clamping force can be adjusted easily and delicately.

Since the support pins are arranged on the yarn introduction side, the solid wax is inclined with respect to the rotating disk, the contact portion between the disk and the wax is reduced, dirt is suppressed, and wax adhesion unevenness is reduced. . In addition, a gap can be formed between the solid wax positioned on the yarn introduction side and the rotating disk, so that the yarn can be smoothly inserted into the gap and the yarn is By contacting the edge portion of the wax, the edge portion of the solid wax can be prevented from being consumed more unevenly and the uneven consumption of the solid wax can be prevented.
