Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a method for producing cover ring yarn using a double twisting machine.

[Prior art] In the conventional manufacturing of covering yarn, as shown in FIG. , the thread 51, 52 that has passed through the spindle 53 is passed through a passage hole provided at the axis of the spindle 53, and is pulled out from the bobbin 54 supported on the spindle 53.
This is done by wrapping it around the Thread 51.52
If the yarn is stretchable, such as an elastic yarn, a pair of rollers (not shown) may be provided before and after the spindle 53 to regulate the degree of stretching of the yarn between them.
The tension cannot be adjusted. Therefore, it is not possible to obtain a covering yarn with a wide variety of variations by adjusting both the tension of the core thread and the threads wound around the core thread. Furthermore, since only one thread is pulled out from the bobbin 54, it is difficult to simultaneously wind two winding threads around the core thread with a predetermined tension, respectively, to obtain a special thread. K Problems to be Solved by the Invention] In view of the above points, the present invention has as its first problem a plurality of winding threads that are simultaneously wound around a core thread, heating of which is performed simultaneously with the covering operation during the covering operation, and , 'iR2 aims to make it possible to change the tension of the winding yarn and the core yarn during the covering.

[Means to solve the problem]

For the first problem, the axial center of the spindle shaft of a double twisting machine has a yarn storage disk that is provided integrally with the spindle shaft and has a yarn guide hole that is continuous with the yarn guide hole provided in the spindle shaft. A large-diameter package is placed concentrically with the small-diameter package in a stationary state and has the same axis as the small-diameter package, and a core pulled out from the large-diameter package The yarn is placed in the balloon guide without passing through the spindle shaft, and the first wrapped yarn pulled out from the small diameter package is guided into the spindle shaft from the top, and sent out of the double twisting machine from the yarn accumulator, and then While guiding the yarn to a balloon guide provided above the spindle shaft, the yarn is double-twisted during this time, and a second wrapped yarn pulled out from a package provided outside the double-twisting machine is guided into the spindle shaft from the bottom thereof. The yarn is fed out of the double twisting machine from the yarn storage disk without interfering with the first wrapped yarn, and guided to the balloon guide provided above the spindle shaft in the same way as the first wrapped yarn. As the three types of yarns pass through, the first and second wrapping yarns are wound around the yarn pulled out from the large diameter package to obtain a covering yarn. To solve the second problem, appropriate tension was applied to the yarns pulled out from each of the large-diameter package, the small-diameter package, and the package outside the double-twisting machine supported on the spindle shaft of the double-twisting machine using tensors. Get the covering yarn.
