2. Description of the Related Art Filaments such as nylon and polyester obtained by melt spinning are generally wound on a bobbin in a winding step and commercialized, for example, as a cheese-like package. In recent years, the speed of melt spinning has been increasing, and it has become necessary to wind at a high speed of 3000 m / min or more in winding. Such a high-speed yarn winding method is such that while winding a yarn on a bobbin mounted on one spindle of an automatic switching winding machine equipped with two spindles, the middle of the yarn being wound is changed to the other. The automatic switching winding method, in which the thread is hooked by introducing it into the groove of an empty bobbin mounted on the spindle, has become mainstream.

Since the quality of the above-mentioned thread hookability and thread switchability has a great influence on the productivity, it is required to maintain the success rate at a high rate at all times. For this reason, the groove provided on the bobbin greatly contributes to the success rate of the yarn hooking property and the yarn switching property. For this reason, a bobbin having a good thread gripping property is required for reliable threading and switching.

Various bobbins having improved thread gripping properties have been created so far. For example, in Japanese Examined Patent Publication No. 6-13389, a thread-holding groove that is pre-clamped is provided in the circumferential direction in the vicinity of the end of a bobbin, and zigzag grooves are formed on both sides of the groove, which alternately have scale-like peaks.

However, in the prior art, when the crest is formed in a scale shape, the crest does not have a sufficient sharpness difference, so that the thread cannot be hooked sufficiently, and The grip force becomes weak. Therefore, the yarn hooking property and the switching property cannot be sufficiently improved. Further, when the bobbin is made of paper, there is a problem in that the strength of the scale-like crest portion is weak, and thus it is impossible to maintain a gripping force similar to that of a new product when recycled.

Further, regarding the cross-sectional shape of the groove, the opening angle (δ in FIG. 2 and ζ in FIG. 3) of the groove on the outer surface of the bobbin in both the thread introducing portion and the thread gripping portion is the opening angle of the groove at the bottom ( It is preferable that it is larger than γ in FIG. 2 and ε in FIG. 3, and the opening angle of the bottom groove is 30 degrees or less.

It is preferable that the opening angles δ and γ be larger than ζ and ε, respectively. This is because the thread is easily introduced into the groove, and if δ and γ are ζ and ε, respectively.
If it is smaller than the above range, the width of the introduction port of the groove becomes smaller and the easiness of being introduced into the groove of the thread becomes smaller. Since the groove has two kinds of portions having different groove widths, it is easy to guide the yarn into the groove when the yarn is introduced. Therefore, the certainty of catching the yarn in the groove is improved, and the effect of the present invention can be further exerted.

In producing the groove for gripping the thread, a cutter having openable and closable blades at regular intervals is provided on both sides of the thread, and cuts with the blade of the cutter in the circumferential direction of the paper tube. Create a groove to put in. When making this groove, each time the cutter is advanced a certain length, only one side of the blade provided on the side surface is opened and a cut is made in the groove side surface. After that, the blade on the side surface is closed, and the cutter is advanced in the circumferential direction of the paper tube by a certain length, and this time, the blade provided on the opposite side surface opened earlier is opened to make a cut in the groove side surface. By repeating such work, a cut is made in the groove side surface.
