Abstract

PURPOSE:To obtain a uniform composite yarn free of twist unevenness and loop, etc., by passing the first yarn through the second yarn feeding member, unwinding the second yarn longitudinally from the second yarn feeding member, and winding and doubling the second yarn around the outer circumference of the first yarn. CONSTITUTION:The yarn 2A unwound from the first feeding member 1A is passed through the axial path in the second feeding member 1B and combined with the second yarn 2B unwound from the second feeding member 1B. The second yarn 2B is wound around the first yarn 2A to form a composite yarn by rotating the second feeding member 1B round its own oxis. The produced composite yarn is wound in the form of a package 9.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application of the Invention) The present invention relates to a yarn doubling method and an apparatus therefor, and more specifically, to a method and apparatus for spinning yarn, and more particularly, to a yarn doubling method and an apparatus therefor. be done.

(Prior art and its problems) In order to give texture and characteristics to textiles, original yarns are doubled, or various yarns are combined into doubling and twisting to create unique yarns that suit the purpose. is accomplished.

A conventional doubling device is shown in FIG. A first yarn supplying body and a second yarn supplying body 1B are arranged side by side, and the first yarn (referred to as ``hajito'') is pulled out in the axial direction from each yarn supplying body IA, IB (vertical removal). The two filament bodies and the second filament body 2B are guided to the snell guides 3A and 3B while forming a nog route. Bifilar body 2
A.

2B are then brought together by a guide 4 and given a predetermined degree of tension by a tensioning device 5. The tensioned side fiber bundle is wound onto a winding body 9 that rotates in the direction of arrow 8 via a traverse guide 7 fixed to a traverse spar 6 that interlocks with a traverse mechanism (not shown).

This type of conventional yarn doubling machine simply aligns the yarn bodies 2A, 2B from both yarn supply bodies IA, IB at the guide 40 portion. As a result, both thread bodies 2A and 2B are wound on the winding body 91C in such a manner that they repel each other under the influence of static electricity generated during winding. For this reason, when the yarn is twisted in the next step, a difference occurs in the amount of the yarn body pulled out from the winding body 9, which causes yarn breakage and the like. In particular, when yarns having different shapes or physical properties are combined, there is a large difference in the amount of pull-out during heating, resulting in frequent twisting unevenness, yarn breakage, etc.

(Technical Problem of the Present Invention) The present invention has been solved by the conventional doubling machine, which is used for winding by simply pulling the threads together, and when heated due to repulsion of the thread bodies due to static electricity, differences in physical properties, etc. Due to the difference in the amount of pull out, uneven twisting, thread breakage, and loose! The technical problem to be solved is to create a defect in the yarn, etc. (focusing on it, and to eliminate the conventional defect by winding the 20th yarn body around the first yarn body.

(Technical means of the present invention and its effects) In order to solve the above-mentioned problems, the present invention provides technical means for winding and doubling the 20th filament body around the first filament body while rotating it, and A technical measure is adopted using a second yarn feeder with an axial passage inside it.

Adoption of this means means that the 20th yarn body wound around the second yarn supply body is vertically unraveled with respect to the first yarn body passing inside the second yarn supply body. As the thread rotates, the 20th thread body winds around the 10th thread body. That is, since the second thread body is wound around the tenth thread body and wound around the winding body,
It becomes possible to eliminate the problems of the prior art described above.

(Example) Please refer to FIGS. 1 and 2. One first yarn feeder is fixed to the creel device 10, which is set approximately at the center KfR in the machine width direction,
Two tenth yarn members wound around one first yarn supplier are released from the vertical winding. A second yarn supplying body IBK whose fine details pass through the axis of one of the first yarn supplying bodies.
The filament body 2B is wound. The second yarn supplying body 1B has a passage extending in the axial direction therein. This passage is formed by a glossy braid passing through the center of the second yarn supplying body 1B.

The two 10th filament bodies that have been released from the vertical position are Snell Guide 3.
, the first tension device 5A, and the internal axial passage of the second yarn feeder 1B, and are pulled out in the direction of the Snell guide 4.

On the other hand, the second yarn body 2B, which is vertically removed from the second yarn feeder IB, forms ballooning due to the unwinding, thereby causing the rotation of the two tenth yarn bodies. 1st while turning
The filament is wrapped around two filaments and pulled out to the Snell guide 4. The spun yarn body 11 whose snell has passed through the id 4 passes through the second tension device 5B, and is wound around the winding body 9 rotating in the direction of arrow 8 by the traverse guide T fixed to the traverse spar 6. be done.

In this embodiment, there are two tension devices asA.

5B, but when threads 2A and 2B made of the same material are combined and wound, even when threads 2A and 2B have different thicknesses and physical properties, they have excellent conjugation and familiarity. If it is suitable, the first tension device 5A1r can be omitted. As for the tension degree, for example, when the synthetic fiber yarn of 150d is used as the first filament body 1A, and the synthetic fiber yarn of 75d is used as the 20th filament body 1B, the first tension device 5A has a tension degree of 152,
A tension degree of 15f can be assigned by the second tension device 5B.

In a non-example, the first and second yarn supply bodies IA.

1B is used, but the second yarn supplying body 1B may be used as the final stage, and a plurality of first yarn supplying bodies may be used.

The yarn body 2B of the second yarn feeder 1B as the final stage must be vertically removed, but one person in the first yarn feeder is required to remove the yarn body by rolling the yarn feeder. It can also be a drawer. For example, when combining and winding three types of filaments, two types of filaments that will become $1 filament are pulled together or one is wound around the other filament, and then the third type is wrapped. The second filament wound with
The tenth yarn body may be passed through the internal axial passage of the yarn supplying body and wound around the second yarn body which has been vertically removed and unwound.

(Effects) According to the present invention, since the tenth yarn body is simply passed through the inside of the second yarn supplying body, there is no need to drastically change the design of the yarn doubling machine, and the yarn doubling machine can be installed at low cost. Can be provided. In the present invention, if the pulling speed of the thread body is constant, the winding diameter of the second thread supplying body becomes gradually smaller, and the 20th thread body is pulled out by one unraveling. The length decreases and the number of wraps per unit length increases. However, compared to the number of times of heating in the next step, the unevenness can be ignored and does not reduce the quality of the spliced fibers. Therefore, the feeding of the 20th yarn body from the second yarn supplying body does not require any special control, and the operation is easy.
