JPH06200519A - Joint structure of sheet or the like - Google Patents

Abstract

PURPOSE:To provide a joint structure which has god productivity, high strength and exhibits a joint function by only forming a woven part and a nonwoven part to form a joint part, and constructing the nonwoven part to be connected to the other wove part. CONSTITUTION:A woven part 5a and a nonwoven part 5b of a warp 2 are alternately disposed at designated spaces to form a joint structure in the selvage 1 of woven fabric. In this case, the intertexture of a weft 3 to the warp 2 is partially skipped in the woven direction to be nonwoven, or a part of the warp 2 of the multiple texture is made nonwoven. Subsequently, a joining part is formed on the selvage 1. A fringed body of the warp 2 of the nonwoven part 5b alternates with the woven part 5a of the multiple texture, and the warp 2 of the joint part is fixed to apply equal force to the joint part. Thus, the strength can be increased as a whole.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a woven belt which is mainly used as a reinforcement and joint by being sewn to the periphery of a soft ground burying sheet for civil engineering, a curing sheet for construction and the like.

[0002]

2. Description of the Related Art Conventionally, this type of woven belt has been
Weaved to form a number of laterally elongated holes at specified intervals along the longitudinal direction of the weaving belt, such as those proposed as fixed belts for civil engineering sheets in No. 62-15683 and No. 62-14185. There were things. Further, there is also one in which a large number of vertically elongated holes are formed by fusing with a hot knife along the longitudinal direction of the woven belt and at predetermined intervals.

However, the former one has a slow weaving speed due to a complicated weaving method and is inferior in productivity, and the lateral oblong hole portion is weak against the tensile force in the belt width direction. However, the belt itself was coarsely woven and the belt itself was weak, and I was worried about strength. The latter one has a drawback that the strength of the belt is greatly reduced because the warp is cut.

Therefore, the inventor of the present invention has proposed a woven belt for joints, which solves the above-mentioned problems, by Japanese Utility Model Laid-Open No. 1-177285. The structure is a structure in which one or a plurality of thick cords are alternately formed with a weaving portion and an exposed portion at predetermined intervals along the longitudinal direction of the woven belt. Since the woven belt for joints of sheets and the like has high strength, it has a feature that it can be suitably used as a reinforcement and joint for a soft ground burying sheet for civil engineering and a curing sheet for construction. However, in addition to the warp, a thick cord and a supply device therefor must be prepared, and since the thick cord is not fixed to the woven fabric, there is a drawback that a strong tensile force extends to form an unbalanced joint.

[0005]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned drawbacks of conventional products, and provides a simple and strong joint structure by only weaving warps and wefts that are the same as or similar to the weaving surface. It was developed for the purpose of proposing it.

[0006]

According to the present invention, the joint structure such as a sheet is formed by alternately forming the woven portions 5a and the non-woven portions 5b of the warp 2 in the selvage 1 of the woven fabric at predetermined intervals. Solved the problem. A preferred embodiment of this structure is that the selvage 1 comprises a weft 3 and a woven portion 5a of warp 2 continuous from the woven surface of the woven fabric, and a non-woven portion 5b of only the warp 2, or the selvage 1 is woven. Woven part 5a of multiple weave by weft yarn 3 and entanglement yarn 4 to warp yarn 2 which are continuous from the woven surface of cloth, and woven selvage portion 5c having the same structure as the woven surface and a part of warp yarn 2 of the selvage portion It is a non-woven part 5b.

[0007]

With such a structure, weaving of the weft yarn 3 is partially skipped in the weaving direction with respect to the warp yarn 2 to make it non-woven, or a part of the warp yarn 2 woven by multiple weaves is made non-woven. By simply doing, it is possible to form a jointable portion in the ear portion. Since the tufts of warp yarns of the non-woven portion are present alternately with the weaved portion of the multi-woven portion, there is no movement of the warp yarns of the joint portion, a uniform force is applied to the joint portion, and the overall strength is increased.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an organization chart showing a first embodiment of the present invention. The cross section is shown in FIG. In this example, a woven portion 5a of the warp yarn 2 and the weft yarn 3 is formed on the selvage portion 1 of the plain weave narrow woven fabric, and a non-woven portion 5b for letting the weft yarn 3 escape from the selvage portion and leaving the warp yarn 2 at a predetermined interval. They are formed alternately. As shown in Fig. 2 (b), there is nothing on the back surface of the non-woven portion 5b.
Is only exposed. That is, in order to have such a structure, the non-woven portion 5b in a non-woven state is formed by not weaving all of the wefts 3 continuous from the woven surface of the normal weaving structure.

FIG. 3 is an organization chart showing the second embodiment. In this example as well, the selvage 1 is composed of the woven part 5a and the non-woven part 5b, but the woven part 5a is a multi-weave structure made up of weft yarns 3 continuous from the woven surface of the woven fabric and entangled yarns 4 to the warp yarns 2. In the non-woven part 5b, a part of the warp yarn 2 of the selvage part forms a weave selvage part 5c having the same structure as the weave surface, and the rest of the warp forms the non-woven part 5b. That is, as shown in FIGS. 4 (b) and (c), the non-woven part is formed on the selvage selvage part 5c in which the weft thread is entirely contained and is formed in the same manner as the other woven surface.
5b is present. The above examples are for narrow woven fabrics, that is, woven belts, and such woven belts are sewn to the periphery of a sheet or the like and used for joints. May be contacted.

[0010]

As described above, according to the present invention, since the joint portion is formed only by forming the woven portion and the non-woven portion, the productivity is good, and the non-woven portion is different from other woven portions. Since it has a continuous structure, it is strong enough to fulfill the joint function.
