DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the method of the present invention and the apparatus used therefor will be described with reference to the drawings showing the embodiments. As shown in FIG. 1, the cylindrical tension disk receiver 10 is provided so as to extend from one side peripheral wall to the other side peripheral wall and from the outer peripheral wall in an obliquely upward direction in the cylinder.
First thread groove (horizontal groove) that allows thread to pass from the lateral direction
11 is provided, communicates with the inner end of the first thread groove 11 inside, and extends in the longitudinal direction (axial direction, longitudinal direction) of the cylindrical tension disk receiver 10, and A second thread groove (vertical groove) 12 that penetrates from one side peripheral wall to the other side peripheral wall is provided. The second thread groove (vertical groove) 12 is adapted to allow a thread to be inserted in the vertical direction. Further, a circular thread stabilizing receiving portion 13 is provided below the second thread passing groove 12.
At the time of use, the lower end screw portion 14 of the tension disk receiver 10 is attached to the mounting portion 1 to which the receiver 10 is attached.

Stick to. As shown in the figure, one tension lower disk (lower plate) 3 is provided at its center with a through hole 18 through which the disk receiver 10 can be inserted. The lower plate 3 has a truncated cone shape. A through hole 19 is also provided in the other tension upper disk (upper plate) 2 in a form in which the lower plate 3 is turned upside down.

As shown in FIGS. 2 and 3, the upper plate 2 and the lower plate 3 are inserted and attached to the tension disk receiver 10 so that the upper plate 2 and the lower plate 3 are overlapped with each other. Insert 6. As shown in FIG. 2, the thread 6 is stretched, and as shown in FIG. 3, the stretched thread 6 is inserted between the upper plate 2 and the lower plate 3.
Then, as shown in FIG. 4, the upper plate 2 is lifted upward with the thread 6. When the thread 6 enters the first thread groove 11, as shown in FIG. 5, the inside of the second thread groove 12 is lowered, and at the same time, the upper tray 2 is lowered. This enables threading with one touch, as shown in FIG. The yarn 6 is stored in the yarn stability receiving portion 13 below the second threading groove 12.

Next, the present invention will be compared with a conventional example. Figure 8
When the thread 6 is abutted between the upper tray 2 and the lower tray 3 to pass the thread 6 and apply tension as in the conventional example shown in FIG. However, according to the present invention, the tension disk receivers 1 located inside the upper and lower tension disks 2 and 3 are easily rubbed with each other.
The thread 6 is prevented from coming off due to the presence of the first thread groove 11, and the thread 6 is prevented from coming off due to the presence of the first thread groove 11. Since the tension can be evenly applied and the upper plate 2 can be lifted by the thread 6 and the thread 6 can be passed through the first thread groove 11 with one touch, the work can be performed quickly. I can do it.
