FIG. 2 is a right side view of the disk 22 as viewed from the yarn path Z in FIG. 1. The yarn Y is guided by the lower yarn guide 49, the guide roller 28 and the upper yarn guide 50. This shows the relationship between the state in which the yarn path Z is formed and the rotation direction of the disk 22 and the wax body 12 with respect to the yarn path Z and the arrangement of the pins 40.

As shown in FIG. 2, the wax body 12 and the disk 22 rotate in the direction in which the yarn Y is sent out in the running direction of the yarn Y. The yarn path Z is formed at a position offset by the radius of the guide roller 28 with respect to the rotation center O of the disk 22 and the wax 12, and all the pins 40 are on a concentric circle Q centered on the rotation center O (pressing surface 43 is concentric circle Q
The pin 40a is disposed at a position passing through the rotation center O in a direction opposite to the yarn path Z with respect to the rotation center O and in a direction substantially perpendicular to the yarn path Z. The pins 40b, 40c are arranged near the yarn path Z, and the arrangement angle between these adjacent pins 40a, 40b, 40c (the angle formed by connecting two adjacent pins and the rotation center O).
θ ₁ , θ ₂ , and θ ₃ are unequal angles, and the pins 40a, 40b, and 40c are arranged at unequal intervals in the circumferential direction of the wax body 12. In this case, the yarn path Z is made up of the pins 40a, 40b, 40c.
P _b point of intersection with the arrangement circle Q, and p _c, the angle theta ₄ relative to the rotation center O of the pins 40a, theta ₆ is not the same, the angle theta ₆ is larger than the angle theta _4, the yarn path Z is the vertical line The upper thread guide 50 against the guide roller 28 so as to be inclined with respect to

Angle theta ₇ is formed so as to differ for, for example,
Angle theta ₅ is, to be larger than the angle theta ₇ pins 40
b, 40c are arranged.

The unequal spacing of the pins 40a, 40b, 40c is set as follows. That is, the angle difference between each of the arrangement angles θ ₁ , θ ₂ , θ ₃ and the intersection angle θ _P formed by connecting the two intersections p _b , _pc and the rotation center O is set to 10 ° or more. Is located. Moreover, they are arranged such that the mutual angle difference between the arrangement angles θ ₁ , θ ₂ , θ ₃ is 8 ° or more. By satisfying both of the above two conditions, the wax body 12 is uniformly cut to such an extent that no problem occurs.

Next, the operation of the present invention will be described.

As shown in FIG. 1, the yarn Y runs while being sandwiched between the disk 22 and the wax body 12, and is subjected to waxing therebetween. In this case, the thread contact surface 12 of the wax body 12
The pin 40 for positioning a has a tip shape of the pin 40,
Since the portion on the outer peripheral side of the wax body 12 is formed in a cut shape, even if the arrangement radius of the pin 40 is increased as much as possible, the tip of the pin 40 does not contact the outer peripheral edge of the wax body 12. Accordingly, the diameter of the disk 22 can be increased, the running yarn can be stabilized, and the wax body 12 rotates stably, so that the wax body 12 is consumed uniformly. Further, at the tip of the pin 40, an arc-shaped pressing surface 43 that is short in the radial direction and long in the circumferential direction of the wax body 12 is formed.
2 can be prevented, and the tip of the pin 40 can be moved toward the inside of the wax body 12.

During waxing, the wax 12 has its thread contact surface 12a sequentially shaved by the running yarn Y. At this time, the pins 40a, 40b, and 40c are arranged at irregular intervals as described above. As a result, a groove (straight shaved portion) G is formed on the thread contact surface 12a of the wax body 12, and the groove G engages with the pins 40b, 40a, and 40c, and the wax body 12 moves rightward in FIG. Thus, even if the thread contact surface 12a of the wax body 12 is strongly shaved and a new groove G is formed, the formation position of the groove G does not become the same position, and a large number of grooves G are formed. And the wax body 12 is uniformly shaved.

As a result, the wax 12 is prevented from being scraped at the same angular position, and the thread contact surface 12a is scraped evenly, so that the problem that the wax 12 is scraped in a star shape as in the prior art can be solved. It becomes possible.

[0038]

In summary, according to the present invention, the running yarn can be stabilized and the wax body can be uniformly consumed.
