Description

Description: TECHNICAL FIELD The present invention relates to a thread layer reed used for warp preparation, and more particularly to a thread layer reed that can also serve as a yarn alignment comb.

[Conventional technology]

The conventional thread-layer-divided reed has a structure in which a crushed portion 16 is attached to the lower surface between every reed wing 14 as shown in FIG. 2 as shown in FIG. The yarn layer is divided into _two yarn layers y ₁ and y ₂ by pushing down the yarn layer with respect to the yarn layer or lifting the reed.

[Problems to be solved by the invention]

When performing the above-mentioned division work, when the number of the yarn layers to be divided is one, it is very simple and does not cause any problem.
If the yarn layer to be divided there are a plurality, i.e., composed of a plurality of Somaki beams b ₁ ~b ₄ more yarns layers when bisected respectively, Somaki beam b as shown in FIG. 4 it was one of the prerequisites nothing between ₁ ~b ₄ and the split reed 11. Because the yarn layer is divided Somaki beam b ₁ ~b ₄ side relative該筬11, i.e., a direction opposite to the traveling end of the yarn,
This is because it is difficult to achieve the purpose if a deflecting roll or the like exists between the coarsely wound beam and the reed. Further, for example, when such a division work is to be performed immediately after gluing, it is extremely inconvenient and almost impossible with the conventional reed to efficiently perform the work at a very narrow interval between the squeeze roll and the drying zone. .

In the present invention, even when a diverting roll, a draw roll, a glue bath, a squeeze roll, and the like exist between the coarsely wound beam and the yarn layer reed, that is, for example, immediately after gluing, the yarn layer division is very It is an object of the present invention to provide a thread layer reed that can be efficiently and smoothly performed.

[Means for solving the problem]

An object of the present invention is to arrange short reeds every other long reed, and close the closed portion in a gap between the short reed and the fixed reed on one of the left and right sides, and the short reed is closed. This is achieved by a thread layer split reed provided to protrude 2 to 15 mm above the upper surface of the section.

The closing portion may be any material as long as it closes the space between the adjacent long and short reeds so that the warp does not fall below the position, and may be provided using various materials. Further, the structure may be such that the lower reed frame is buried up to the so-called crushed portion, or a space may be provided between the closed portion and the lower reed frame. The distance between the upper surface of the closed part and the lower reed frame is 20 to
It should be 40mm.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings showing an example of a thread layer divided reed of the present invention.

FIG. 1 is a front view showing an example of a thread layer divided reed of the present invention. The reed 1 has left and right reed frames 2a, 2b and a lower reed frame 3,
A short reed 5 is provided every other long reed 4, and a blind portion 6 is provided 2 to 15 mm below the upper end of the short reed 5. The reason why the length of the short reed fins 5 is set to be 2 to 15 mm longer than that of the crushed portion 6 is to hold the thread layer located on the crushed portion 6 so as not to fall during the thread layer dividing operation. If the length of the short reed 5 is less than 2 mm, the thread layer of the crushed portion 6 may come off. If the length is more than 15 mm, the operability when hooking or removing the thread layer during the splitting operation is poor, usually 5 mm. A degree is desirable.

The short reed 5 is located at the center between the long reeds, and the crushed portion 6 may be on either side, but it must be provided on a fixed side.

Next, a specific method of dividing a yarn layer using the above-described yarn layer division reed will be described.

First, an example in which a four-layer coarsely wound beam is uniformly divided into eight layers will be described with reference to FIGS. 5 to 11. The number of warp yarns of the coarsely wound beam is preferably about 200 to 1,000. The reason is that when the number of warp yarns exceeds 1000 and the density is mixed, the linear shape of the short reed dents 5 becomes thin and the strength of the reed becomes weak.

FIG. 5 shows a state in which four yarn groups Ya, Yb, Yc, and Yd are passed through a yarn layer dividing reed 1 which can also serve as a yarn alignment comb. In this case, the dividing sticks Sa, Sb, Sc , Sd.

Figure 6 is a yarn layer split reed to the right to move about 10 mm, the Ayahimo 7 behind該筬1 while the yarn group Ya is divided into two Ya ₁ and Ya ₂ shows a state in which depressed the stick Sa Insert (see Fig. 11).

FIG. 7 shows that after inserting the twill cord 7 in FIG. 6, the stick Sa is raised to the position shown in FIG. 5, so that the yarn groups Ya ₁ and Ya ₂ both return to the position shown in FIG. Move the yarn layer reed 1 about 10 mm to the left to remove the yarn group Ya ₂ from the short reed 5,
a is lowered, and all the yarn groups Ya ₁ and Ya ₂ are lowered. This operation is a feature of the divided reed 1 of the present invention. Another twill yarn 7 is inserted between the yarn layers of the yarn groups Ya and Yb.

In FIG. 8, the same operation as described in FIG. 6 is repeated for the yarn group Yb, and the yarn string 7 is inserted behind the reed 1 while the yarn group Yb is divided into two.

FIG. 9 shows a state in which the same operation as that described in FIG. 7 is repeated for the yarn group Yb, and the entire yarn group Yb is dropped to the lower portion. The twill cord 7 is also inserted between the yarn layers of the yarn groups Yb and Yc.

FIG. 10 shows a state in which the above operation is repeated for the yarn groups Yc and Yd, and the division of each yarn group into two has been completed.

 FIG. 11 is a side view of FIGS. 5 and 6 described above.

Next, a method of dividing into eight layers in a wet state after the squeeze roll 8 will be described with reference to FIGS. 11 and 12. FIG.

In this case, the reed 10 in FIG. 13 does not need to use the thread layer divided reed 1, but may be a normal thread alignment comb. First, the yarn groups Ya, Yb,
Three yarns (not shown) are inserted between the yarn layers of Yc and Yd behind the yarn alignment comb and moved to the rear of the squeeze roll 8 as shown in FIG. , Sb,
Example 1 was replaced with Sc, and a stick Sd was disposed further above, and a thread layer split reed 1 that could double as a thread alignment comb was used.
By repeating the above operation, the wet split rod 9
Shows that it is now possible to insert

 FIG. 13 shows a side view after the eight-layer division is completed.

Note that the thread layer division reed 1 that can also serve as the thread alignment comb behind the squeeze roll 8 can be removed after the completion of the eight layer division.

〔The invention's effect〕

According to the above-described operation, the time required to divide the strand into eight layers on the conventional sparsely wound beam side and to replace the twill cord each time the yarn passes through the thread alignment reed is greatly reduced.

Also, the precondition that there is nothing between the coarsely wound beam and the divided reed, which was a drawback of the conventional divided reed, and the operation of changing the twill string formed on the coarsely wound beam side is completely unnecessary, Multi-layer division in a short time and in a narrow space became possible.
