Description

[Detailed description of the invention] This invention relates to a method for drying sized yarn.

Generally, as shown in FIGS. 1 and 2, a plurality of beams 81
The threads Y1 to Y4 respectively pulled out from ~B4 are formed into a single sheet through the reed blades 11 of the diagonal reed 1, passed through the gluing section S, and after being pasted, are formed into multilayers such as two layers. It is divided and sent to a drying section consisting of a drying cylinder 9, a hot air drying device, etc., and dried. In this case, when dividing into two layers, the threads Y1 to Y4 of each beam are first and θ second beam 81,
Yarns Yl and Y2 let out from B2 and the fifth and fourth beams B5. Thread Y5 drawn out from B4. Divide it into Y4 and insert the split string into the divided part on the downstream side of diagonal reed 1, and
After passing between the attached rollers, the threads separated by the split strings were guided onto the drying cylinder 9 by guide rolls 8A and 8B according to the divisions. As a result, the pitch of the thread, that is, the thread Y
The pitch interval between 1 and Yl and the pitch interval between Y5 and Y4 become narrower, and the adjacent yarns (for example, Yl and Yl) adhere to each other,
It was often left to dry.

By the way, when drying on a drying cylinder after pasting,
It is necessary to prevent adjacent glued threads from adhering to each other. For this purpose, it is conceivable to widen the thread pitch. However, if the conventional dividing method is used to widen the yarn pinch on the drying cylinder, the lengths of the drying cylinder, guide rolls, gluing rolls, diagonal reeds, etc. must be set that long. However, there was a drawback that the device was large in size.

This invention has been proposed in view of these facts, and aims to provide an undivided method for sizing that allows the yarn pitch on the drying cylinder to be set widely without increasing the size of the device. .

That is, the gist of the present invention is to alternately divide the yarn after sizing into two layers, thereby increasing the distance between the yarns and feeding the yarn into a drying section such as a drying cylinder.

The present invention will be described in more detail below based on the accompanying drawings.

As shown in FIG. 3, the threads Y1 to Y4 drawn out from the beams 81 to B4 are put into each of the diagonal reeds 1 one by one. After passing through the diagonal reed 1 and being neatly arranged in a line, the threads are formed into a single sheet by the thread alignment roll 5 and sent to the gluing roll 6.

Furthermore, it is guided by guide wheels 8A and 8B and fed into the drying cylinder 9. This is the same as the conventional method, but the present invention further provides a fourth reed on the upstream side of the diagonal reed 1 when the reed is in progress.
A twill reed 3 as shown in Figure (A) is installed in advance.

In this twill reed 3, long layers 31 and short layers 36 are alternately erected on an opening holder 30. The short strata 63 located between the long strata 31 divides the growth feathers into two gaps 35A and 35B. One of these two gaps 5
58K, a stepped portion 64 is formed.

Next, the operating state of the twill reed 6 will be explained.

As shown in Figure 4), each beam 8 is located above the long layer 61.
Thread the threads Y1 to Y4 from 1 to B4.

In this state, the thread Y1 of the #2 beam 81 is lowered into the gap 55A on the right side separated by the short layer 33 (see FIG. 4(B)). Next, as shown in FIG. 4(C), move the layer holding body 50' to the right side in the figure, and the short layer 5
The yarn Y2 of the second beam B2 is lowered onto the stepped portion 34 in the left gap 35B separated by the second beam B2. Then, as shown in FIG. 4(D), the thread Y3 of the third beam 83 is
The layered holder 30 is moved to the left so that it is above the right # gap 55A, and then the thread Y5 of the sixth beam B3 is lowered. Furthermore, as shown in FIG. 4(g), the layered holder 30 is moved to the right, the thread Y4 of the fourth beam B4 is positioned above the left-hand gap 54, and the chain thread Y4 is then lowered. do. Then, the first and third beams 81 and the yarn Yl of B5 are placed in the gap 55A on the right side partitioned by the short layer separation.
, Y3 is on the step 34 between ljJ 55B on the left.
and the thread Y2 of the fourth beam B2°B4. Y4 are distributed to different levels (Fig. 4(E)). Then, the dividing rod DR2 is inserted between the yarn in the right gap 55A and the yarn on the step part 34 in the left gap 35B, and when the dividing rod DR2 is lifted, the yarn is divided into groups Yl and Y3 and Y2.・Divided into Y4 group. At the time of starting, a split string is inserted between the groups of the divided threads on the downstream side of the diagonal reed 1, and after passing through the gluing section, the threads are passed through the gaffid roll 8 as divided.
A, 8B guide it onto the drying cylinder 9. During normal operation, the twill removal reed 6 and the ``NU'' spool are removed. Then, the yarn from each beam passes through the yarn alignment roll 5 by the diagonal reed, is made into a single sheet, and is guided to the gluing section. Sizing is carried out in a single sheet.The single sheet of yarn that has been sized and sent out from the gluing section by the gluing roll 6 and the squeezing roll 7 is moved to a pair of guide rolls 8A, When reaching 8B, it is divided into two sheets, a group of Yl/Y3 and a group of Y2/Y4, according to the above-mentioned division.In other words, as shown in FIG.
The yarns + and Y3 are guided by the second guide roller 8BiCY, and the yarns Y4 and Y2 are guided by the first guide roller 8A to the drying cylinder 9Vc, respectively. And the yarns Yl and Y3 are in the upstream drying drum 9Ail'l! : The yarns Y2 and Y4 are respectively wound around the drying drum 9A on the upper side of the figure, dried, and then wound around a beam (not shown).

As described above, according to the present invention, since the yarns pulled out from each beam 81 to B4 are divided alternately, the yarn pinches in contact with the drying cylinder 9 are uniformly distributed, and the pitch between the yarns is can be uniformly larger than the conventional one, so
Even without increasing the length of the drying cylinder, etc., the yarn pinch can be set large and the inconvenience of drying while adhering to adjacent yarns can be eliminated.

Furthermore, the fact that the yarn can be pinched to a large extent means that the pitch per yarn can be increased when passing through the diagonal reed, and as a result, the occurrence of fluff accumulation in the reed is eliminated.
