The present invention is one of the worsted spinning process, in the widely installed gill process and Bobinoir process, it is possible to obtain a uniformly prepared sliver as a high drift, in particular It is related with the draft apparatus which eliminated the nonuniform part generate | occur | produced in the fiber bundle by sliver continuous.

Conventional roads (C) and bobbins (D) are either needles such as Faller 10 or porcupine roller 11, as shown in FIGS. 1 and 2, respectively. It was the apparatus which controlled the sliver 12 by (10a) and (11a), and provided a draft.

Moreover, the apparatus which enabled the draft in conjunction with the recent speed-up is, for example, a balloon roller 13a and a lower apron 13b instead of a poler or pocufine as shown in FIG. Needles are used, such as a device in which an intermediate roller 14 composed of) or an intermediate roller 14 of a double apron 14a, 14b is installed as shown in FIG. Draft without.

This makes it possible to achieve high speed and high loft, but compared with using conventional polo or pocup fine,

(1) While the degree of uniformity of the sliver is inferior, the yarn in the spinning machine is often cut.

(2) The effect of correcting the defective sliver of the previous process is small, and sometimes it is encouraged.

(3) In particular, there has been a drawback in that it is completely incapable of preventing the occurrence of non-uniformity caused by terminal continuation of the sliver.

That is, as shown in FIG. 3 and FIG. 4 with respect to the points (1) and (2) described above, any of the high-drift devices developed in recent years are apron-type or a similar type thereof, and can be high-drifted. As a condition, the basic basis is to insert ideally good slivers. However, in practical terms, it is not considered that there is absolutely no intervening of slivers or slivers of defective parts. The defect enlargement is performed beyond the conventional low drift device, and many cases of cutting of the yarn in the spinning machine lead to generation of the yarn and deterioration of the quality of the yarn.

Next, point (3) described above will be described.

As shown in FIG. 5, before the sliver 12 supplied from the can 15 disappears, the sliver 212 pulled out of the full pipe can 215 waiting to be supplied next. A part of the tip 212a of the () is overlapped and joined to the sliver rear end 12a of the can 15.

By the way, in this apparatus, since the needle is not used like electricity, this joining portion does not drift normally and becomes uneven, and this uneven portion must be removed later. Due to this loss of work, the effect of the characteristic high speed and high production was not sufficiently exerted, and the effect was extremely large especially in the case of the completion of the automatic doping device.

On the other hand, in terms of quality, this kind of non-uniformity is sometimes overlooked because it is not surfaced to an observable state, reaches a spinning plane, radiates, and becomes a reflection, which is knitted to produce a product. Only after that, the defect was discovered and there was a possibility of becoming a big problem.

The reason for being hesitant about the adoption of Hydraft Bobina is attributable to this quality insecurity.

In view of the above, the present invention is to coexist the needle and the apron to utilize only the advantages thereof, while controlling the mass movement by the sliver joint connection by the action of the needle, while driving the apron at this front roller By rotating in the towing state, the apron's sliver gripping is made extremely smooth, and by this, the hydra is precisely and surely performed, the uniformity is improved, and the connected slab is connected. It is a new draft device that allows you to get missing slivers.

Hereinafter, the configuration of the present invention according to the embodiment shown in the drawings as follows.

6 and 7 are examples of the draft apparatus according to the present invention, wherein (1) and (101) in the conveying plane are front rollers, and (5) and 105 are rear rollers. In the draft device A shown in FIG. 6, a middle roller composed of a opaque fine roller 2, a balloon roller 3a, and an apron 3b between both front and rear rollers 1 and 5, 3) are arranged in order, and the draft device B of FIG. 7 is a double apron of the upper and lower parts instead of the balloon roller 3a and the apron 3b in the above-mentioned deft device A of FIG. It is set as the high-drift apparatus by arrange | positioning 104a and 104b to the intermediate roller 104. As shown to FIG.

The lower apron 3b or 104b is formed by the rollers 6 and 106 at the foremost part of the plurality of rollers, which are installed at both ends thereof, that is, the pocufine rollers 2 and 102. Drive rotation.

Therefore, the surface of these rollers 6 and 106 is formed in a sawtooth-shaped or coarse surface, and actively pulls out the apron 3b or 104b by a friction force, and rotates it. As a result, any of the intermediate rollers, from the aprons and the balloon rollers, or the double aprons, are rotated by the lower aprons 3b or 104b being pulled out by the front rollers 6 and 106, and thus the rear part as before. The dropping property of the sliver gripping surface generated by the feeding and entering state by the rollers 7 and 107 does not occur, and the sliver 12 and 112 are rotated because they are always tense and rotated. In the middle rollers are fed smoothly.

This apron drive system exhibits its effects particularly when the amount of tripping is high. Also, the Pocu Fine Rollers (2) and (102) are positioned between the front roller (1) and the intermediate rollers (8) or (104) and the needle tips (2a) and (102a) at the slivers (12) and (112). Rotate in the same direction as the transition of the sliver, with some indentation.

As a result, the slivers 12 and 112 moving between the intermediate roller 3 or 104 and the front roller 1 or 101 are of a predetermined thickness here, so that the front roller 1 or ( The final drift in this drift device is received to be spun and discharged in 101), and the fiber is trying to move into a group in the shunting or parallel hunting. The front rollers (1) and (101) are controlled by the Pocu Fine Rollers (2) and (102) that rotate the needle tips (25a and 102a) in the burrs (12) and (112). Is introduced.

Draft is usually hardly imparted between the rear and middle rollers, and a predetermined amount is imparted between the middle roller and the front roller. In the present invention, the amount of drift is, for example, the rear roller and the middle roller (apron). It is 1.00 in the case, 0.90 in the Pocu Fine roller part, and 12.0 times in the front roller.

The sliver is fully stretched in this hydratomic part and is controlled by the Pocufine needles, which results in fewer quarters. Particularly, the grouping of the polymerized fibers by the sliver connection is effectively controlled by the Pocu Fine Roller, which enables the production of a sliver with extremely good uniformity.

As described above, the present invention, in the process of exhaustion, or bobbin process, between the front roller and the rear rollers, the pocufine rollers on the front rollers, and the rear a middle roller consisting of double aprons or balloon rollers and aprons. The apron of the middle roller is driven and rotated by the front roller of the apron installation, and the slender from the rear roller is rotated by rotating the apron. The elongated state does not become a curved shape and is extremely smoothly gripped and derived. Therefore, the high drift is always carried out correctly, and as a comb of the Pocu Fine Fowler is consumed, the fiber is sufficiently controlled. Especially, the slab connected to the sliver is eliminated, so that the uniformity is always good. It is spun and produced as a sliver free.

In addition, according to the present invention, the middle a roller consisting of a lower apron and an upper balloon roller or a double apron that is pulled and rotated by a pookfine roller and a front roller can be easily installed by modifying a conventional road or bobbin. In addition, the high drift can be achieved by the arrangement of the pocu fine rollers and the driving of the apron, and the operation rate can be improved while maintaining the quality and eliminating the work loss of eliminating defective parts of the connection part.

Claims (2)
