Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a double reed provided with two rows of feathers in the front and back, mainly for use in looms for double-sided pile fabrics such as double-sided towels.

(Conventional technology) Traditionally, there are two types of reeds: single reeds, which have one row of feathers, and double reeds, which have two rows of feathers in the front and back. However, double reeds have their own advantages and disadvantages, such as a wider range of threads that can be used than single reeds.

By the way, in a conventional double reed, a large number of rows of feathers are arranged at a constant interval in the longitudinal direction between the upper and lower reed frames that are parallel to each other at a constant interval, and two groups of feathers are arranged at a slight interval in the front and rear. The positional relationship between the front and rear feather rows was set so that each feather in the rear feather row was located exactly midway between the front feather rows.

(Problem to be solved by the invention) When weaving, for example, a double-sided towel using the conventional double reed as described above, as shown in Fig. Two pile warp threads (also called top threads) a and two ground warp threads (also called bobbin threads) b were passed alternately through the threads at a distance from each other.

By the way, since the pile warp a is not stretched as tightly as the ground warp b in order to form a trap, it is twisted due to the twisting of the pile warp a, as shown by the dashed line in Fig. 4. , there was a risk that the two pile warps a would intersect.

For this reason, for example, when weaving a double-sided towel with different piles (the pile warp has two colors), the other pile warp, which is different from the planned pile warp, will stand out on the surface and the color pattern will be unified in each part of the towel. I was getting used to it. In addition, when characters or patterns are formed at predetermined positions on a towel using pile warp yarns, and the area around the characters or patterns is woven on so-called terry cloth, there are no traps around the towel fabric, such as those shown in Figure 5. This occurs in some places, significantly lowering the value of the product.Therefore, in the past, workers manually cut out the traps using scissors, etc., but this work requires skill and also reduces the value of the product. This method had the disadvantage that (some of the pile warp threads) were cut off, which caused the threads to fall out and weaken the fabric.

This idea was made in view of the points mentioned above.
It is an object of the present invention to provide a reed which can eliminate the above-mentioned conventional drawbacks caused by the crossing of two pile warp threads passed between two feathers.

(Means for solving the problem) The gist of this invention to achieve the above-mentioned purpose is that in a double reed, each feather in the rear row group is The pile warps are arranged to be shifted to the right or left by approximately 1/4 width of the spacing between adjacent feathers, and the two pairs of pile warps are completely separated by the feathers on the front row side or the back row side, and the pairs are separated. This is to prevent the pile warp threads from crossing each other.

(Function) According to the double reed of this invention, the gap between the blades formed by the blades on the front row side and the rear row side is at a ratio of 1:3 in the longitudinal direction of the reed. By passing one pile warp between them and passing the other pile warp and two ground warps in order between the adjacent feathers with wide gaps, weaving is carried out in the conventional manner. During this process, the two pile warp yarns forming a pair are completely separated by the blades of the reed and do not cross each other.

(Example) Hereinafter, an example of this invention will be described based on the drawings.

FIG. 1 is a partially cutaway perspective view of the first embodiment;
FIG. 2 is a partially enlarged sectional view taken along the line -- in FIG. 1.

In these figures, 1 is a pair of upper and lower reed frames,
Each reed frame 1 is supported by support rods 2 at both ends, and is arranged in parallel with each other at a constant interval. And between the upper and lower reed frames 1, 1, there are long thin reed blades 3.
They are arranged as shown in FIG. That is, the front row wing group 3A is arranged at regular intervals in the longitudinal direction near the front end of the reed frame 1, and the feather row group 3A is arranged at regular intervals in the longitudinal direction near the rear end of the reed frame 1. It consists of a rear row side feather row group 3B arranged at intervals, and a front row side feather row group 3A and a rear row side feather row group 3B.
There is a slight gap (for example, about 2 mm) between the two. Then, the front row side feather row group 3A and the back row side feather row group 3
The intervals between the wings 3 of B are equal, and furthermore, the intervals between the wings 3 of the front row row group 3A are the same as those of the rear row row group 3B.
The blades 3 are arranged so that they are shifted to the left by 1/4 width of the spacing between adjacent blades, so that the gap between the blades 3 formed by the blades 3 on the front row side and the rear row side is in the longitudinal direction of the reed. 1:3
It is configured so that

Although not shown in the drawing, spacers are usually provided at both the upper and lower ends of each blade 3 to ensure the spacing between the blades 3, which extends along the longitudinal direction of the reed frame 1. There is. Furthermore, in the embodiments described above, the interval between adjacent feathers 3 is not particularly specified, but this is because it is appropriately set depending on the type of yarn or fabric used.

When using the double reed of the above embodiment,
As shown in Fig. 2, one of the two pile warps a, a forming a pair is passed between the narrowly spaced feathers 3, and
The other pile warp a is passed to the left between the widely spaced wings 3, and the ground warps b and b are passed between the widely spaced wings 3 at an appropriate interval. Therefore, since the pair of pile warps are separated by the wing 3, even if the pile warp a is slightly twisted, the two pile warps will not intersect, unlike in the past. .

FIG. 3 is a sectional view corresponding to FIG. 2 showing a second embodiment of this invention. The blades 3 of 3B are arranged to be shifted to the right by 1/4 width of the interval between adjacent blades, and the method of use is also completely the same as in the previous embodiment. In addition, in FIG. 3, members common to those in the previous embodiment are indicated using the same reference numerals.

(Effects) As explained above, the double reed of this invention is constructed so that the pile warp threads, which conventionally tended to intersect, are separated by the intermediate reed blades, so that the following effects are achieved.

(1) Even if the paired pile warp yarns are twisted due to yarn twisting, they do not cross each other, so even when weaving double-sided piles with different piles, it is possible to This prevents the colored threads from floating up and creates a pile fabric with the desired color pattern.

(2) In addition, when forming characters or patterns using the traps of the pile warp threads, traps do not occur in the surrounding area of the ground as in conventional methods, making it possible to weave double-sided pile with high commercial value.

(3) The feathers are positioned between the paired pile warps, and reed beating is performed in a state similar to a single reed.
The texture and texture of the woven double-sided pile,
It is similar to weaving using a conventional single reed and is of good quality.

(4) It is convenient in that it is structurally the same as a conventional reed, and can be used simply by changing the position of the thread threaded between the blades of the reed, and can be applied to existing looms as is.
