Description

[Detailed Description of the Invention] The present invention relates to an improvement of a wire twisting device.

A double-twisting device that collects core wires and side wires and twists them twice per rotation of the twisting machine body to create twisted wires is well known. The wire transfer capstan was not equipped with a feed-out capstan, and the wire transfer depended solely on the pulling force of the take-up capstan, which not only placed an excessive burden on the take-up capstan but also made it impossible to adjust the tension of the wire. First, high-tension filaments are false-twisted and then final-twisted, which requires a large amount of force, and also causes various inconveniences, such as difficulty in making the tension of the side wires uniform, which adversely affects the quality of the product. There were drawbacks to it.

The present invention has been made to eliminate such drawbacks.

This will be explained below using exemplary diagrams.

The figure shows the overall configuration of the proposed twice-twisting device.

8 is a tension roll, 9 is a rotary bow, 10 is a core wire feeding capstan, 11 is a tension roll, 12 is a measuring device, 13 is a batten, 14 is a voice, 15 is a front plate twisting device, 1
6 is a main shaft frame, 17 is a turn roll, 18 is a twice-twisting rotary bow, 19 is a cradle, 20 is a rear false twisting device, 21 is a take-up capstan, 22 is a winding bobbin, 23 is a drive shaft, and 24 is a stepless It is a transmission.

The core wire and side wires are gathered at the voice 14 and twisted twice to form a rotating bow 1.
8 is twisted twice each time it rotates, and is wound into a stranded wire on the winding bobbin 22.

In this double-twisting device, the present invention provides, in addition to the take-up capstan 21 provided on the cradle 19, a core wire delivery capstan 10 and a side wire delivery capstan that collectively sends out the filament drawn out from the side wire supply bobbin 1. 4.

Next, the effects of the present invention will be described.

It is well known that a take-up capstan is provided in the cradle for wire transfer in a double-twist gathering device, but the present invention provides a take-up capstan in addition to the take-up capstan provided in the cradle.
Since a feed-out capstan for actively feeding the core wire and side wire is provided, the tension of the wire to be transferred can be arbitrarily adjusted by adjusting the feed-out speed by the feed-out capstan with respect to the take-up speed by the take-up capstan. can.

In the present invention, adjustments are made to appropriately loosen the tension of the filaments.

In the conventional double-twisting collecting machine, the wire transfer depended solely on the pulling force of the take-up capstan, so it was inevitable that the tension in the wire would increase.

For the same reason that it takes a large amount of force to twist and tighten a bundle of strongly taut filaments, conventional devices that use a large amount of tension in the filaments have the disadvantage of requiring a large amount of force to heat. Furthermore, there were drawbacks such as the plating peeling off due to contact friction between the strands, and small waves occurring in the final product despite false twisting, which impaired the straightness.

However, in the present invention, since heating can be performed with the tension of the filament moderately relaxed as described above, the above-mentioned drawbacks of the conventional apparatus can be overcome.

Furthermore, in the past, it was extremely difficult to maintain uniform tension on the multiple wires pulled out from the multiple side wire supply bobbins 1, which had a negative impact on product quality. Since all of the filaments that are to be removed are fed together by the side wire delivery capstan 4, the tension on all the side wires becomes uniform, which contributes to improving the quality of the product. An excessive burden was placed on the take-up capstan, but the present invention provides a capstan for sending out the core wire and side wire in addition to the take-up capstan, so the burden placed on the take-up capstan is greatly reduced.

As mentioned above, the present invention is a double twisting device that can achieve exceptional effects compared to conventional devices.
