Abstract

PROBLEM TO BE SOLVED: To provide a new method and a related device for producing a composite yarn by blending a filament in view of the fact that, in a conventional spinning machine, a roving cannot be wound on a filament of synthetic fiber. SOLUTION: This device works as follows: a filament 13 of synthetic fiber unwound off a filament bobbin 12 is passed, via a guide roller 14, in between a front bottom roller 6 and a front top roller 7, and then wound, via a guide 15, under unidirectional twisting, by the aid of a traveler 17 rotating along a ring 16, on a filament winding bobbin 18; concurrently, on driving a 1st driving unit 10 in a short time, a roving 20 unwound in a short time off a roving bobbin 19 is wound on the filament 13 under unidirectional twisting, thus producing the objective filament 21, i.e., a composite yarn, where portions entangled with a slub 22 are partially puffed.

FIG. 1 is a side view of a filament composite yarn mixing and manufacturing apparatus according to an embodiment of the present invention, FIG. 2 is a schematic configuration diagram of the filament manufacturing apparatus of FIG. 1, and FIG. 3 is a bobbin roller of each drafting apparatus. 1 is a schematic configuration diagram of a roller stand 1 in which a back bottom roller 2 and a back top roller 3, a middle bottom roller 4 and a middle top roller 5, and a front bottom roller 6 and a front top roller 7 are mounted in pairs. A draft device 9 having a guide 8 attached is provided in the vicinity of the back bottom roller 2 and the back top roller 3, and the back bottom roller 2 and the middle bottom roller 4 of the draft device 9 are provided as shown in FIG.
Is rotated by the first drive device 10, and the front bottom roller 6 is rotated by the second drive device 11.

The filament 13 made of synthetic resin drawn from the filament bobbin 12 passes between the front bottom roller 6 and the front top roller 7 via the guide roller 14, and is guided from the guide 15 to the ring 16.
The filament winding bobbin 18 is wound around the filament 13 by twisting the filament 13 in one direction by a traveler 17 that rotates along with, and the roving 20 drawn from the roving bobbin 19 passes through the guide 8 of the draft device 9. The roving thread 20 guided between the back bottom roller 2 and the back top roller 3 and further pulled out from the back bottom roller 2 and the back top roller 3 has the middle bottom roller 4
And the middle top roller 5 and the roving 20 drawn from between the middle bottom roller 4 and the middle top roller 5 is guided between the front bottom roller 6 and the front top roller 7.

In the apparatus of this embodiment having such a structure, the filament 13 continuously drawn from the filament bobbin 12 passes between the front bottom roller 6 and the front top roller 7 via the guide roller 14,
When the filament 13 is wound in one direction on the filament winding bobbin 18 by the traveler 17 rotating from the guide 15 along the ring 16,
When the driving device 10 is driven for a short time, the roving yarn 20 drawn from the roving bobbin 19 is drafted and drawn out between the middle bottom roller 4 and the middle top roller 5,
The filament 13 guided between the front bottom roller 6 and the front top roller 7 and passing continuously between the front bottom roller 6 and the front top roller 7 is unidirectionally moved by the filament winding bobbin 18. Since the roving yarn 20 that is pulled out in a short time is wound around the filament 13 in one direction, the slab 2 that is a part of the roving yarn 20 is wound as shown in FIG.
The filament 21 in which the part around which 2 is wound is partially swollen is manufactured.

As described above, in the present embodiment, the first driving device 10 is provided to the filament 13 which continuously passes between the front bottom roller 6 and the front top roller 7 and is wound by being twisted in one direction. The roving yarn 20 guided from the middle bottom roller 4 and the middle top roller 5 to the front bottom roller 6 and the front top roller 7 by driving the first and second driving devices 10 and 10 is stopped by the first driving device 10
And the brake draft between the back bottom roller 2, the back top roller 3, the middle bottom roller 4, and the middle top roller 5, and the middle bottom roller 4, the middle top roller 5, and the front bottom roller 6. If the total draft between the main draft and the front top roller 7 is large, that is, the roving 20
Is strongly stretched, and the roving yarn 20 guided between the front bottom roller 6 and the front top roller 7 becomes thin, so that the slab 22 of the roving yarn 20 of the filament 21 becomes small, as shown in FIG. If the total draft is small, that is, if the roving 20 is not stretched,
The slab 22 of the roving thread 20 guided between the front bottom roller 6 and the front top roller 7 becomes thicker, as shown in FIG.
As shown in (b), the slab 22 of the roving 20 of the filament 21 becomes large, and further, by appropriately setting the drive interval of the first drive device 10, the filament 21
The spacing and the length of the slab 22 can be arbitrarily changed.

According to the present invention, while the filament 13 is twisted in one direction and wound, the roving yarn 20 is spun by the drafting device 10 to have an arbitrary thickness and length, and is wound around the filament 13. Since the wound filament 21 is manufactured, the thickness, the length and the interval of the slab 22 can be arbitrarily set, and the filament 21 which has not been obtained until now can be manufactured.

Since the surface of the filament 21 manufactured in this way is smooth, the wound roving 2
Since there is a risk that the slab 22 of 0 moves, by winding another filament on the filament around which the slab is wound so that the slab 22 does not move, or by applying a quick-drying adhesive to the filament 21, The roving may be fixed.

[0012]

As is apparent from the above description, in the method and apparatus for producing a composite yarn of filaments on which rovings are wound according to the present invention, the rovings are wound while the filaments are twisted in one direction and wound. Since a filament wound with a roving yarn is manufactured by spinning the filament into an arbitrary thickness and length and winding the filament around the filament, the thickness, length and interval of the roving yarn in the filament can be arbitrarily set. There is an advantage that the filaments not obtained can be easily manufactured.
