Description

[Detailed description of the invention] a. Industrial application field The present invention uses a fastener element (occlusal element, hereinafter simply referred to as an element) formed by a coiled continuous filament to simultaneously weave the tape material. This invention relates to a woven slide fastener woven into the element woven portion on one side edge of the .

b. Prior Art Conventionally, in this type of woven slide fastener, the coiled elements to be woven are made of a material that is much thicker and stiffer than the warp and weft, and is woven in a coiled state, so that the reaction force is As a result, the fastener chain tends to extend vertically and the coil loop tends to tilt, so simply weaving an element into the tape end cannot maintain the stability of the pitch of the coil and the good upright state of the coil loop. It was difficult. For this reason, various improvements have been made in this regard.
For example, the warp threads of the element weaving part are arranged more densely than the warp threads of the tape main body (Tokuko Sho 46-7018
No.), but although this could prevent the coil loops from tilting, the fastener chain expanded and contracted in the vertical direction, and there was still a problem with pitch stability.
In addition, the fixing warp is arranged so as to run over two elements and then pass under the basic weft between these elements, forming the double weft between the elements into a loop shape. By placing a pad between the upper and lower legs of the element, the resistance to torsion of the element is improved and the stability of the pitch is improved.
No. 56-60504), but this had a problem in that the fastening chain was thick and lacked flexibility because the fixing warp was bundled with the weft.

c. Purpose of the invention The applicant of the present invention has improved the conventional drawbacks to maintain a good upright state of the coil loop and increase the stability of the pitch of the coil without impairing the flexibility of the fastener chain. Although we previously proposed a woven slide fastener, the present invention is a further improvement on this, which strengthens the maintenance of the normal posture of the occlusal head, which is particularly important for occlusion, and increases weaving stability when weaving elements. The purpose of this invention is to obtain an excellent woven slide fastener.

d Structure of the invention The structure of the invention is as described in the claims for utility model registration, and in particular, the upper fixed warp 2 extending almost straight on the upper surface of the upper leg part c of the element, and the lower leg part of the element as well. In a woven slide fastener having lower fixed warp threads 3 extending almost straight on the lower surface of d and coil tightening warp threads 6 and 6' arranged between the fixed warp threads, at the end of the element woven part on the occlusion head side 〓Warp thread 7 for interlocking
and the weft thread 4 is bent and wound around the warp thread 7 for closing the space, thereby closing the space between the occlusal heads b of the elements. To explain this more specifically according to the illustrated embodiment, the drawing shows that a continuous filament of synthetic resin monofilament is wefted into a double pick to form an element that draws a coil-like loop, and this is attached to the fastener tape section. 1 is a perspective view showing the main part of the woven slide fastener of the present invention, which is woven into one side edge of the tape at the same time as the weaving of the tape.
is a flat coil formed by winding a continuous filament 1' that has been pressurized and deformed at regular intervals in a spiral shape while forming an inverted part a and an occlusal head b by bending it at a pressurized deformation part. Each unit element is connected to other unit elements at both ends, that is, at both inverted portions a, and the flat coil 1 constitutes an element row B as a whole. Reference numeral 2 denotes upper fixed warp threads extending substantially straight along the upper surface of the upper leg portion c of the element, and coil tightening warp threads 6 are alternately arranged between these upper fixed warp threads. Reference numeral 3 denotes lower fixed warp threads extending substantially straight along the lower surface of the lower leg portion d of the element, and like the upper fixed warp threads, coil tightening warp threads 6 are alternately arranged between the lower fixed warp threads. 4 is a weft yarn, and since it is inserted into a double pick by a needle loom, two yarns form one weft, and in the element weaving section, the upper and lower fixed warp yarns that extend almost straight line the upper and lower legs of the element. They are arranged in a loop near the side of the body,
In the tape portion, the tape material is intertwined with the warp threads 5 to weave a tape fabric. When the weft threads 4 run on the upper leg side of the element, the upper fixed warp threads 2 and the coil tightening warp threads 6 are alternately arranged vertically in a plain weave structure, and when the weft threads run on the lower leg side of the element, Also, the lower fixed warp threads 3 and the coil tightening warp threads 6 are alternately arranged vertically in a plain weave structure. Although the upper and lower fixed warp threads 2 and 3 are depicted as straight lines in the drawing, in reality they are slightly wavy up and down due to the tension of the weft thread 4, and run almost straight overall. be. Reference numeral 5 denotes warp yarns for the tape fabric, which are intertwined with the weft yarns 4 to weave the tape fabric. Reference numeral 6 denotes warp threads for tightening the coil, which are alternately arranged between the upper and lower fixed warp threads. 1' is woven at 1/1, intertwined with the weft 4 and the continuous filament 1' to weave a flat coil, and 6' is the interwoven warp 7 and the upper fixed warp. 2nd
Since the weft thread 4 passes below the lower fixed warp thread 3, the coil fastening warp thread 6' is different from the other coil fastening warp threads 6, and the weft thread 4 passes under the lower fixed warp thread 3. 〓 between the upper legs of the elements c
The weft yarn 4 is intertwined with the weft yarn 4 in the middle between the lower leg portion d and the lower leg portion d. 7 is a warp for closing the gap, which is used to fill and close the gap between the legs of adjacent elements at the end of the occlusal head side of the element weaving part.
The weft threads 4 inserted into the double picks are wrapped around the warp threads 7 for closing the gap by turning the weft threads 4, and are bent and arranged.

e Effects of the invention This invention has fixed warp threads extending almost straight in the longitudinal direction of the fastener chain, and coil tightening warp threads arranged between the fixed warp threads to maintain the coil loop in a good upright state and improve the pitch of the coil. This is a more effective version of the woven slide fastener, which has further improved the stability of the element.At the end of the occlusal head side of the woven part of the element, between the legs of adjacent elements, the warp for closing the space is connected by the weft. Because it is bent and wound, the gap between the legs is filled and closed, the occlusal head is maintained in a normal posture, and the occlusion of the fastener is good, and the warp threads for closing the gap are kept in a normal position. The weaving stability during element weaving can be improved by bending and winding the weft and the weft, and these excellent effects are due to the coil tightening warp 6' placed at the end of the coil tightening warp. It has an unprecedented and excellent effect of preventing slippage and allowing it to be held for a long period of time.
