Problems solved by technology

Therefore, even if the mandrel is moved to the inside, such a form of equipment cannot be used to manufacture concealed zipper strips with joint heads all facing inward
Since the fixed weft yarn guide bar is placed above the mandrel, the double weft fixed weft yarn will run over the mandrel and become slack when it is removed from the mandrel after weaving along several pitches, so the zipper element cannot be securely locked. be fixed

Embodiment Construction

[0027] The preferred embodiments of the method and equipment for manufacturing the concealed zipper strip of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] The dark woven zipper made by the method and equipment of the present invention is in Figure 4 to 7 Shown in. In the zipper strip 1, a series of connecting heads 4, a series of connecting parts 5 and a series of upper and lower limbs 6 winding zipper elements 2 are woven in the inner edge of a zipper tape 3, and there are two core cables 7 It is inserted through the zipper element 2. The zipper belt 3 is woven by a plurality of ground warp yarns 8 and a double weft ground weft yarn 9. The zipper element 2 is connected to the zipper tape 3 so that the connecting head faces the inside of the zipper tape 3. There are three fixed warp yarns 10 passing over the element limb 6; two of the fixed warp yarns 10 are arranged between the two core cables, and the other fixed w...

Abstract

An apparatus for manufacturing a concealed woven slide fastener stringer comprises a frame disposed at a side where foundation warp yarns of a fastener tape are to be arranged and having core-cord-inserting holes; a mandrel projecting from the frame for shaping a thermoplastic resin monofilament into a fastener element; an anchoring-weft-yarn carrier bar and a foundation-weft-yarn carrier bar both disposed downwardly of the mandrel; a rotor revolvable about the frame and having a monofilament guide hole; an anchoring-warp-yarn heddle disposed above core cords; a foundation-warp-yarn heddle disposed below the core cords; and a hook lever vertically movably disposed before the foundation-weft-yarn carrier bar for pushing the outer core cords downwardly.

Description

Technical field [0001] The invention relates to a method and equipment for manufacturing a concealed zipper strip, in which a zipper element wound with a core cord inserted in it is fixedly woven on a zipper tape to be folded by a weaving device such as a knitting machine Turn inside the inner edge. Background technique [0002] Japanese Patent Application No. 7-67402 has disclosed a method of manufacturing a concealed zipper strip on a knitting machine. The method is to feed a thermoplastic resin monofilament to one side of the zipper belt's woven opening to form it into one The upper and lower limbs ground warp, connecting warp and double weft ground weft of the zipper element are woven into the zipper tape with the wound zipper element, so that the connecting heads face the inner side of the zipper tape, so as to fix the zipper element. [0003] Japanese Patent Publication No. 57-35645 has disclosed a device for manufacturing a regular woven zipper strip and exposing the conne...
