SOLUTION: According to this tail thread ending method, a winding start filament is held on a thread holding part extending in the circumferential direction on the surface of the end part of a paper tube, and subsequently, in a package formed by a tail thread 1 wound to be engaged with a regular traverse area and a thread taken up in the regular traverse area, the tail thread 1 is cut by a blade surface and the tail thread 1 is drawn out. The scissors has a blade surface formed by one member, the member is curved, a blade surface is formed on the substantially end part, and the blade surfaces are brought into sliding contact with each other to fulfill a cutting function.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tail yarn joining method and a tail yarn cutting scissors. For details,
A tail yarn that can be easily pulled out and spliced by cutting the tail yarn using a blade surface in a package in which the yarn to be wound is gripped by a yarn gripping portion that extends in the circumferential direction on the end surface of the paper tube. And a scissor for tail thread cutting.

[0002]

2. Description of the Related Art First, tail yarn joining will be described.
In order to continuously use the wefts and processed yarns of the woven fabric, the tail yarn 1 which is the starting yarn and the yarn 2 of the surface layer of the yarn package to be used next are continuously connected. In order to be able to use the thread, a thread connecting operation generally called a tail transfer shown in FIG. 1 is performed.

[0003] As a method for connecting the tail yarn, there is a yarn package shown in Fig. 2 wound up by a general winding method described in JP-A-62-280172 or JP-A-6-321424. After the wound yarn package form grips the starting yarn on the yarn gripping portion, the tail bunch 3 is formed, and the tail yarn 1 wound until the tail bunch 3 is engaged with the regular traverse region is formed. In the tail yarn joining operation, the tail bunch is removed by hand and the tail yarn 1 is pulled out to join the yarns. Further, in a package in which the tail bunch 3 is removed in advance and the yarn end is fixed with a tape, the tail tape is peeled off, the yarn is pulled out, and the yarn is connected. Further, in the yarn package shown in FIG. 3 wound by the winding method described in Japanese Patent Application No. 10-251598, the shape of the wound yarn package is such that the yarn grip extending circumferentially on the end surface of the paper tube is provided. A tail yarn 1 wound from the gripped point to the engagement with the normal traverse area without forming the tail bunch 3 from the gripped point, and a yarn wound in the normal traverse area The tail yarn 1 protruding from the yarn gripping portion toward the normal traverse region is drawn out and spliced by hand. However, it is not possible to remove the tail bunch 3 by hand and pull out the tail thread 1 or to manually pull out the tail thread 1 that is in direct contact with the paper tube from the thread gripping portion toward the regular traverse area and connect the thread. There has been a problem that the work efficiency is very poor and difficult, and a work load is caused.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to grasp a thread which starts to be wound on a thread grasping portion extending in a circumferential direction on an end surface of a paper tube, and then until the thread is engaged with a regular traverse area. In the package formed from the tail yarn wound on the regular traverse region and the tail yarn wound on the tail yarn, the tail yarn can be easily pulled out by cutting the tail yarn using the blade surface. . Also, in the tail yarn heading toward the regular traverse region without forming a tail bunch from the yarn gripping portion,
By cutting using the blade surface, the tail yarn can be easily pulled out and spliced. As a secondary effect, it is possible to recycle the paper tube by cutting the paper tube without damaging it.

[0005]

Means for Solving the Problems In order to solve the above problems, the tail yarn connecting method of the present invention mainly has the following configuration. That is, in a package in which a yarn to be wound is gripped by a yarn gripping portion extending in the circumferential direction on the end surface of the paper tube, a tail yarn joining method of cutting the tail yarn using a blade surface and pulling out the tail yarn.

Further, the scissors for tail yarn cutting of the present invention mainly have the following configuration. That is, in the scissors which are constituted by one member and which have a function of cutting the member by bending the member, forming a blade surface at a substantially end portion thereof, and rubbing the blade surface, at least one other than the blade surface is provided. Scissors having a blade surface.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, in a package in which a yarn starting to be wound is gripped by a yarn gripping portion extending in a circumferential direction on an end surface of a paper tube, a blade surface serving as a means for cutting a tail yarn is shown in FIG. 4 may be a sharp blade surface 4 of a commercially available cutter, or a thread cutting scissors blade surface 5 as shown in FIG. More preferably, a slightly obtuse blade surface that does not damage the paper tube is preferable.

[0008] The slightly obtuse blade surface is constituted by a single member as shown in FIG.
A scissor having a function of cutting a blade surface by forming a blade surface at a substantially end portion thereof, and a part other than the blade surface is additionally processed so that the blade surface 6 has a slightly obtuse angle. It may be any one of such members as a part of which is additionally processed so as to have a slightly obtuse blade surface.

Further, in a package in which the yarn to be wound is gripped by a yarn gripping portion extending in the circumferential direction on the end surface of the paper tube and wound without forming a tail bunch from the gripped point, as shown in FIG. A part of the scissors, which is constituted by one member, has a function of cutting the member by bending the member, forming a blade surface at a substantially end portion thereof, and cutting the blade surface by rubbing the blade surface. The work efficiency can be further improved by using a thread which is additionally processed so as to have a slightly obtuse angled blade surface 6 and tying the thread.

[0010]

The present invention will be specifically described below with reference to examples. Nylon 6 yarn with a 100 cm tail yarn wound on the surface of the paper tube by gripping the starting yarn in a slit groove for yarn grip extending in the circumferential direction at the end of the paper tube and forming a yarn layer portion from there. For each of the 40 packages, we asked 20 men and women, each of whom is connecting the tail, to perform the tail thread cutting work. The safety was good (〇 or ×) or the workability was good (〇 or ×). Whether there is a paper tube scratch (visual) (3)
Answers were obtained for two evaluation items. The method of cutting the tail yarn was performed using the blade surface 4 of the commercially available cutter shown in FIG. 4 (Example 1), and the method performed using the blade surface 5 of the commercially available thread cutting scissor shown in FIG. Instead, only one blade is used in the manner of using a cutter) (Example 2), and another blade surface is formed on the side opposite to the blade surface of the threaded scissors rubbing portion shown in FIG. What was done with blade surface 6
(Example 3) was evaluated. Table 1 shows the results.

[0011]

[Table 1] In Examples 1 to 3, the good safety rate was 63% or more and the good workability rate was 75% or more, which was good. In particular, in Example 3, both the safety and workability good rates were 9
At 8%, the paper tube scratch rate was 0%.

[0012]

According to the tail yarn joining method and the tail yarn cutting scissors of the present invention, in a package in which the yarn to be wound is gripped by the yarn gripping portion extending in the circumferential direction on the end surface of the paper tube, the tail yarn is cut by the blade. By cutting using the surface, the tail yarn can be easily pulled out and spliced. Also,
Even if the tail yarn is headed toward the normal traverse region without forming a tail bunch from the yarn gripping portion, the tail yarn can be easily pulled out and spliced by cutting using the blade surface. As a side effect,
By cutting the paper tube without damaging it, the paper tube can be recycled.
