After insertion, when the upward force 74 of the lever 73 is released, the slider 70 is moved downward by the force of the spring 71, and the cap 68 and slider 70 press the deformable ring body 69 from above and below. Due to the pressing force, the deformable ring body 69 is deformed in a circumferentially outward direction and chucks the guide pipe 35 from inside. Since the inner side of the guide pipe 35 is chucked, there is no need to provide an extra length at the upper end of the guide pipe 35 for a portion to be gripped by the chuck. Therefore, the overall height of the guide pipe 35 can be kept low. The technical concept of stacking yarn feeding packages in two stages has the inherent problem that the overall height is high, which tends to cause problems in transportation, transfer, etc., but it is possible to reduce the height. is a huge advantage. Furthermore, the thread end is lightly wound around the upper end of the guide pipe 35, so that the inner chuck 65 does not have any influence on the thread end.

In the above embodiment, the yarn feeding package is transferred to the double yarn twisting machine in a state where it is placed in two stages,
Since it is fed to the double twisting machine as it is,
The labor of supplying the yarn is greatly simplified, and at the same time, it is possible to eliminate clumsiness such as when the upper and lower yarn feeding packages are reversed during yarn feeding.

In the above embodiment, the present invention is applied to a package supplied to a two-stage yarn feeding type double twisting machine, and the two yarn ends of the two yarn feeding packages are wrapped together around a guide pipe. . The two packages inserted into the guide pipe are supplied to the double twisting machine in their set state, and the two yarn ends can be processed simultaneously and efficiently.

In addition, the "non-yarn layer part" at the upper end of the yarn supply package cage
