A slide fastener chain includes a first tape and a second tape. A row of coupling elements is fixed along an inner edge of the first tape. A row of coupling elements is fixed along an inner edge of the second tape. The coupling elements of the first and second tapes being arranged such that the coupling elements of the first tape interdigitate with coupling elements of the second tape so as to secure the first and second tapes together. The chain includes a bottom stop. At least one of the tapes is provided with an extension portion which extends beyond a bottom stop portion of the tape. A width of the extension portion is less than a width of a portion of the tape which does not form part of the extension portion.

Slide fastener chain

A slider body of a slider includes a slider main member and a slider sub-member. The slider main member includes at least a portion of a first blade and at least a portion of a second blade which are connected to each other through a guide column. The slider sub-member includes a pair of first flange sections and is assembled with and fixed to the slider main member. The slider can easily be attached to a fastener chain. Since the slider stably has a predetermined distance between the first and second blades, it is possible to secure satisfactory sliding properties and operability of the slider.

Slider and method for repairing slide fastener

The slide fastener attachment method includes: integrating, by welding or bonding, a fastener chain to which a segmented slider has not been attached and a fastener receiving member, and attaching the slider to the fastener chain after the integration. Thus, welding work operation efficiency is improved, and reduction of production cost can be expected.

Slide fastener attachment method

A method of sewing a fastener stringer includes the steps of conveying a fastener stringer and an attached body to a sewing section of a sewing machine in a state with the fastener stringer superposed on the attached body, and arranging an element guide section in the sewing section of the sewing machine, bending a fastener tape in a direction in which a tape bent section opens, guiding the element rows to the element guide section, and sewing the fastener tape to the attached body. Accordingly, the method enables a sewing line formed by a sewing thread to be disposed at a predetermined position and the fastener tape and the attached body to be easily and efficiently sewn together.

Method of sewing a fastener stringer

A fastener attached product is structured such that a slide fastener is sewn to right and left attached bodies which are bent in a U-shape, and the right and left attached bodies are arranged in a tape surface side to which the element rows of the fastener tape are sewn. Further, the right and left attached bodies come into contact with the outer surfaces of right and left flanges which are arranged in a slider, and the element rows are arranged and exposed between the right and left attached bodies. As a result of this configuration, since the fastener tape is invisible from the outside by the attached body, exposing the element rows can provide the fastener attached product with different design from conventional products and eliminate problems due to degradation in the appearance and design which is caused by the exposure of the fastener tapes.

Method of sewing fastener stringer and method of manufacturing product to which fastener is attached

A harness frame of light weight manufactured from a laminated plate material is disclosed. The laminated plate material comprises (a) a composite material layer comprising a resin matrix and a reinforcing layer formed of reinforcing fibers and (b) metallic layers superposed one each on the opposite surfaces of the composite material layer. In a preferred mode, resin sheets and reinforcing layers of reinforcing fibers are alternately superposed, two metallic layers are set in place one each on the vertically opposite surfaces of the superposed layers, and the layers are heated and compressed with a pressing machine to induce thermal welding of the component layers. The laminated plate material has the metallic layers superposed with high adhesive strength on the opposite surfaces of a composite material layer having a plurality of reinforcing layers embedded in a resin matrix.

A coiled slide fastener element made of a synthetic resin monofilament has a coupling head portion, which has an enlarged width by forming bulging portions so that firm coupling of a slide fastener can be realized.

A woven slide fastener stringer has a web section and a woven filament section defining a longitudinal edge portion and including successive loops formed from a woven plastic filament and each having upper and lower legs and is provided with a plurality of tensioning warp threads and a plurality of loop fastening warp threads both interposed between binding warp threads and adapted to draw the upper and lower legs closely together and hold the loops stably in place on the stringer.

Woven slide fastener stringer

In a woven slide fastener stringer of the type which comprises a row of successively interconnected elongated loops of a plastic filament woven into a longitudinal edge of a stringer tape woven of foundation warp and weft threads, and a pair of groups of upper and lower binding warp threads extending respectively over and under the loops and interwoven with the foundation weft thread, the improvements comprising a gap-filling warp thread extending parallel with and between an outermost one of the upper binding warp threads and the next adjoining upper binding warp thread and also between an outermost one of the lower binding warp threads and the next adjoining lower binding warp thread, and passing alternately over and under the foundation weft thread, thereby tensioning the latter thread to sink substantially halfway between the upper and lower legs of each adjacent pair of loops. Preferably, the outermost upper and lower binding warp threads are disposed in registry with each other to make the foundation weft thread lie substantially perpendicualr to the plane of the fastener stringer between the two outermost binding warp threads. The row of loops thus woven is stably secured in place against angular displacement and held at the proper pitch with respect to individual adjacent loops.
