1 to 4, the seamless elastic belt with a branched structure includes an upper woven belt 1 and a lower woven belt 2. The upper woven belt 1 includes upper warp yarns 3, upper covered warp yarns 4, and upper weft yarns 5. The lower layer woven belt 2 is knitted by crossing the lower layer warp 6 and the lower layer covering warp 7 with the lower layer weft 8, and the upper layer covering warp 4 crosses only the upper layer weft 5. When the lower layer covered warp 7 is knitted by crossing only the lower layer weft 8, it becomes the branch portion 9 of the elastic belt, and the upper layer covered warp 4 and the lower layer covered warp 7 become the upper layer weft 5 and the lower layer weft yarn 8, it becomes the joint portion 10 of the elastic belt, and the elastic belt has a plurality of branch portions 9 and the joint portions 10 alternately arranged Become.

When the branched portion 9 is knitted, the upper covered warp yarns 4 function to form the upper woven belt 1 by intersecting with the upper weft yarns 5 in the same way as the upper warp yarns 3 are knitted. Similarly, the lower covering warp yarns 7, like the lower warp yarns 6, function to form the lower woven belt 2 by interlacing with the lower weft yarns 8. As shown in FIG. When knitting the joint 10, the movements of the upper warp 3, the upper weft 5, the lower warp 6 and the lower weft 8 do not change, and only the movements of the upper covered warp 4 and the lower covered warp 7 change. To change the operation in which the upper covered warp 4 intersects only the upper layer weft 5 and is knitted to the operation in which the upper covered warp 4 intersects both the upper layer weft 5 and the lower layer weft 8. , the single-layer weft structure is changed to a two-layer weft structure. For the same reason, the operation in which the lower covering warp 7 crosses only the lower weft 8 and the lower covering warp 7 crosses both the upper weft 5 and the lower weft 8 is knitted. to change from a single layer weft structure to a two layer weft structure (illustrated by the transition from FIG. 2 to FIG. 3).

In processing by a conventional knitting machine, a plurality of warp knitting needles are passed vertically and one weft knitting needle is passed horizontally to form a knitted fabric by crossing the warp and the weft and weaving them. Based on this, the present invention adds one weft knitting needle as an upper layer weft knitting needle and a lower layer weft knitting needle, and the warp knitting needles are the upper layer warp knitting needle of the upper layer weft 5 and the lower layer warp knitting needle of the lower layer warp 6. , the upper covered warp knitting needles of the upper covered warp 4 and the lower covered warp knitting needles of the lower covered warp 7 . When knitting the bifurcation 9, the upper warp knitting needles and the upper covered warp knitting needles and the upper layer weft knitting needles are crossed to form the upper layer woven belt 1, and the lower layer warp knitting needles, the lower covered warp knitting needles and the lower layer weft knitting needles are formed. are crossed to form the lower layer woven belt 2 . When knitting the joint part 10, the processing operations of the upper weft needles, the lower weft needles, the upper warp needles and the lower warp needles are not changed, and the upper and lower covered warp needles and the lower covered warp needles are passed up and down in a larger range. By doing so, it is possible to intersect both the upper layer weft 5 and the lower layer weft 8 during knitting. That is, the crossed upper weft 5 and lower weft 8 can be regarded as one weft that is a combination of the upper weft 5 and the lower weft 8 .

At least two upper layer warps 3 are arranged between two adjacent upper layer covered warps 4, and at least two lower layer warps 6 are arranged between two adjacent lower layer covered warps 7. are placed. When knitting the branched portion 9, the functions of the upper layer warp 3 and the upper layer covered warp 4 are the same, and the functions of the lower layer warp 6 and the lower layer covered warp 7 are also the same. It only functions to increase the warp content of the When knitting the joint portion 10, the upper layer covered warp 4 and the lower layer covered warp 7 are knitted by crossing both the upper layer weft 5 and the lower layer weft 8 to knit the upper layer woven belt 1 and the lower layer woven belt. 2 are knitted as the same woven belt. To ensure the content of the upper covered warp yarns 4 and the lower covered warp yarns 7 so that no delamination occurs in the joint 10 even after a series of tests during production, for example after being stretched multiple times. is required.

The lower layer weft 8 and the upper layer weft 5 are composite wefts made of nylon yarn and heat-fusible yarn. When cutting the elastic belt, a heat cutting process is used to melt the heat-sealing yarns in the composite wefts closed to avoid fraying at the cut.

The heat-sealing yarn is one of high-temperature polyester material or polyamide low-temperature material, the present invention adopts nylon low-temperature material, and the content ratio of the heat-sealing yarn is different according to different production requirements. to select.

A method of manufacturing the elastic belt is as follows.
