Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a method for end joining sheet-like bodies formed by a large number of yarns in parallel, and particularly relates to a method for joining sheets together, and in particular, beam-to-beam warping sizing (hereinafter referred to as B to B sizing). Connecting warp beams by warp splicing when switching warp beams in 1. This invention relates to a method for connecting warp beams by warp splicing between finished beams and new beams when weaving a coarse-density fabric.

<Prior art> In the case of conventional BtoB sizing, when the sizing of the Aramaki beam on which a large number of warp threads are wound after the warping process is completed, it is switched to another Aramaki beam on which the same number of warp threads are wound and sizing is performed again. At the time of switching, the yarn end of the previous rough winding beam that has already been passed through the sizing machine is divided into multiple pieces, and the yarn end of the newly installed rough winding beam is similarly divided into multiple pieces. Connect departments to each other. Thereafter, the warp threads were rethreaded through 13 pitched comb-shaped reeds (actually, one warp thread was passed between the reed feathers) attached to the sizing machine.

This method required a changeover time of 90 to 120 minutes until sizing restarted, which affected the work surface sizing operating rate.

Furthermore, when weaving a fabric with a low warp density, the warp beams are usually switched by looming the warp beams after passing through a drawing process or by tying them on the loom using a tying machine.

These methods require a total time of 5 to 6 hours for looming after pulling, and 2 hours for the on-machine tying method, and although the labor of looming can be saved, there is the problem that threads are raised due to tying errors. There is a problem with work efficiency.

<Purpose of the Invention> The present invention technically eliminates the drawbacks of the conventional technology, and provides a method that enables accurate and quick warp splicing without being affected by the thickness of the constituent yarns, the yarn constituent materials, etc. This was reached as a result of research.

That is, in the present invention, when splicing a /-t-shaped body made of warped warp threads formed by paralleling a large number of threads, the terminal part of the previous 7-tipped body and the trailing 7-ted-shaped body are Regarding the method of splicing sheet-like objects over the entire width by stacking the starting ends and gluing the threads at the corresponding positions of each component yarn, a sheet-like object formed by a large number of yarns in parallel. It is an object of the present invention to provide a method for accurately and quickly achieving the connection of comrades.

<4'4 Composition of the Invention> First, a method for joining the ends of a warp sheet in B to B sizing will be described.

FIG. 1 is a schematic side view of the B to B sinong machine, showing a state in which the yarn row is running.

As for the flow of the yarn, the warp yarn a wound around the rough winding beam 1 passes through a tension roll 3, a feed roll 4, a sizing 5, a drying chamber 6, a cylinder dryer 7, and a dancer roller 8.
, an oiling roller 9, and a tip roll 10, the glued warp a'' is wound around the sizing warper purse beam 11.

At this time, the warp threads have passed through 13 reeds A to M.

The adhesive base 2 is shown in FIG. An arm 13 is attached to poles fixed to both sides of the beam stand 12 so as to be slightly wider than the beam width, and is fixed with delts so as to be movable up and down. Also, on the arm 13 is a metal fitting 14 for fixing the reed A-B.
There are two on each side. l-1 as an adhesion method
: As shown in Figure 2, the warp a' wound around the rough winding beam 1
The warp threads a' are sized rapidly and when the sizing is completed, the warp threads a' are held between the rough winding beam IS and the reed A with clips 16, and the portions protruding from the clips are cut.

This becomes the thread end of the warp thread a'. Next, place the Aramaki beam on which the same number of warp threads a have been wound onto the beam stand 12.
The thread ends of the warp threads a are oiled on the reeds A to H, respectively, and then held between the clips 16.

Thereafter, the two arms 13 of the bonding table 2 are lifted up on both sides, and a weight 17 is applied to the end of the warp yarn a' to apply tension uniformly. On the other hand, the warp threads a and a are neatly twisted between the reeds A and B while applying tension uniformly by hand via the presser rod 15 to the ends of the warp threads a. Thereafter, adhesive is sprayed between the reeds A and B using compressed air or an electric sprayer to bond the threads corresponding to each alignment. In order to prevent adhesion to adjacent threads; it is desirable to make the particles of phlegm U as fine as possible, and it is also desirable to cover the reed A-I3 and beam 1 to prevent them from getting wet with adhesive. The adhesive length may be 10 to 20 cn1.

After gluing, apply a jig and cut the boundary line between the unbonded part and the bonded part on the unbonded side (that is, both ends sandwiched by the clips 16).In this case, it is better to make the uncut part α as short as possible. desirable.

FIG. 4 shows a schematic side view of the dock after cutting.

The reason for cutting the unbonded part short (shortening the so-called uncut part α) is that there is a reed in the direction in which the warp threads advance, and if the uncut part α is long, it will get tangled with the adjacent thread at the reed and break. This is because it leads to the occurrence of

Next, iron items with coarse warp density are 1! ′! A method for connecting warp sheet materials when weaving will be explained.

FIG. 5 is a schematic side view of the loom, in which the warp yarns 23 wound around the beam 21 pass through the pack rollers 22, the healds 24, and the reeds 25, and are woven with the Eh threads to form a woven fabric 27, which is then passed through the surf ace rollers. 26 and is wound onto a cross beam 28.

As shown in FIG. 6, the adhesive base 29 is attached to a table 35 with a reed 30.
31 is fixed, and is a device that is attached to the side frame of the loom so that it can move up and down. As shown in FIG. 7, the bonding method is Bt.

This is almost the same as the case of B sizing. When the warp threads wound around the beam 21 are woven and packed, first, the warp opening □ is closed, the warp threads are held between the back roller 22 and the reed 30 by the clips 32, and the portions protruding from the clips are cut off. do. This becomes the yarn end of the warp yarn 23'. Next, a beam 21 on which the same number of warp threads 23 are wound is separately set up, and the ends of the warp threads 23 are passed through the reeds 30 and 31 and held between clips 32.

Thereafter, the adhesive table 29 is lifted slightly above the warp line and a weight 33 is applied to the ends of the warp yarns 23' to apply tension uniformly. While applying tension uniformly by hand to the yarn end of one warp 23 through the presser rod 34, the warp 23 is
, 23' Overlap comrades neatly. The following bonding method is B
This is similar to the case of to B sizing.

Hot melt type, solution type, etc. can be used as adhesives.
Cellulose acetate, vinyl acetate, polyethylene/ethylene
Vinyl acetate copolymer, butyl methacrylic resin, polypropylene, polyamide resin, chiliester resin, moon? Any polymer such as listyrene and copolymers/polyisobutylene can be used.

It is particularly desirable to use an adhesive solution in which a polymer is dissolved in a solvent such as acetone, ethanol, or methanol, which has a low boiling point, in order to dry quickly.

As for the method of applying the adhesive, spraying of adhesive particles or an adhesive solution is preferable in order to prevent adhesion between adjacent yarns, but roller application using a grooved roller or the like may also be used. It is necessary to achieve adhesion only between the threads of each corresponding alignment without adhesion of the threads.

<Example> The present invention will be explained below with reference to Examples.

Example - When switching beams in B2B sizing of Rouyon 50 denier/20 filament and Ester 50 denier/24 filament, the thread end of the Aramaki beam after sizing and the Aramaki beam set at a new 1° angle were compared. The ends of the threads are guided to the bonding table 2 shown in FIG. 3 and overlapped at the same position, and the threads at corresponding positions on both beams are fixed in a aligned state.

After spraying an acetone solution of acetate flakes (5:1jj-i41ch solution) on this kneaded part with an electric sprayer over a width of about 1300 mm and a length of 150 cylinders, the acetone evaporates and separates the individual aligned warp threads. The glued parts were attached all at once.

After that, this adhesive part is passed through a sizing machine as it is, and the sizing beam 11'! ! , I immediately started regular sizing.

As a result, there is no need to rethread the sizing reed as in the conventional method, and it is now possible to switch beams while the warp threads are still threaded through the reed. Therefore, the conventional method required 90 to 120 minutes to switch the beam before sizing beam, but now it can be changed in 25 to 30 minutes, and 1/3 to 1/4 of the time.
It was possible to significantly improve work efficiency and sizing operation rate.

The main conditions for warving and B to B sizing are as follows.

Example-2 When weaving a tarpaulin base fabric of 840 denier/140 filament nylon 66 warp/weft using the following age and conditions, the warp wound around the beam becomes the machine packing cloth. The thread end of the warp beam that has become empty and the thread end of the newly installed warp beam are guided to the bonding table 29 in FIG. 7 and overlapped at the same position. A solution of acetate flakes in acetone (5% by weight solution) was added to this overlapped part using a dynamic spray device.
+ 1830 Hn After spraying over a length of 150 mm, the acetone evaporated and the individual warp yarns were layered together. After that, this bonded part was passed through the heddles and reeds, and weaving started immediately. As a result, it took only 30 minutes for beam cutting to start weaving. This is a significant time reduction compared to the conventional method, which required 5 to 6 hours to tie the loom through the drawing process, and approximately 2 hours using the loom tying method, and greatly improved work efficiency. It was revised to -1I. The main weaving conditions for the tarpaulin base fabric are as follows: 1&1jl (i2fi4 Water Jet Loo

Sizing and greening.

The beam VJ changing time is shortened by several times, and work efficiency and productivity are improved. Moreover, the present invention
Since this method only firmly connects the yarns, it has been confirmed that it is an effective method for creating strong yarn connections even for materials with weak adhesion strength, such as carbon fiber and delicate glass. .
