A plurality of warp threads includes total N adjacent tightening threads each repeats crossing over N second legs at a side of the first tape-surface and crossing over the weft thread at a side of the second tape-surface so as to tighten the coil-shaped element to the weft thread. Said N indicates a natural number equal to or greater than 2. Each tightening thread includes an exposed portion that crosses over the weft thread and is exposed at a side of the second tape-surface. As the N adjacent tightening threads extend, the respective exposed portions of the tightening threads appear at a side of the second tape-surface one-by-one alternately or one-by-one sequentially.

A cover attachment structure includes a sheet-shaped cover member, a base, and a fastener member. The fastener member includes a first element row and a second element row. The base has a recessed groove extending along a surface thereof. Fastener elements of the first element row and the second element row are received in the recessed groove and locked in the recessed groove in a state in which engaging head portions of the fastener elements engage with each other. The recessed groove is configured such that a minimum groove width thereof in a width direction orthogonal to a length direction of the recessed groove is less than 2 times a length, in the width direction, of either one of the fastener elements received in the recessed groove.

Zippers with two sliders used for certain applications function better if the tooth pitch of the zipper teeth is extremely precise, and the pin/box assembly mounted to each end of the zipper is mounted so that the pins of each pin/box assembly are mounted on one zipper stringer and the boxes of each pin/box are mounted on the other zipper stringer. A zipper of such construction is well-suited for use in fastening a mattress cover, a boat cover, an automobile soft-top, and similar articles.

A monofilament having, in cross section, a first width and a second width being orthogonal to the first width and being greater than the first width is helically wound about the circumference surface of the mandrel. Each helical unit included in the configured helix of the monofilament includes a pair of legs, a first coupling portion coupled between said pair of legs, and a second coupling portion coupled between one leg of said pair of legs and the other leg of a pair of legs in an adjacent helical unit. The second width of said first coupling portion is oriented along the axial direction of the mandrel. The first coupling portion in each helical unit in the helix is pressed such that the second width of the first coupling portion is widened in its width direction, thereby forming an engagement head.

A wide top narrow bottom type double-layer zipper that the width of the interlocked bottom interlocking coils is smaller than the width of the interlocked top interlocking coils; the top interlocking coils and the bottom interlocking coils have the same spiral pitch; the top and bottom layers of the wide top narrow bottom type double-layer zipper are vertically aligned and sewed; the diameter of the polyester coils extend spirally around the respective filler cords of the respective bottom interlocking coils monofilament is about 0.02 mm0.1 mm smaller than the diameter of the polyester coils monofilament that extend spirally around the respective filler cords of the respective top interlocking coils; the engaged tooth line of the top interlocking coils at the top cover panel of the zipper slider and the engaged tooth line of the bottom interlocking coils at the bottom cover panel of the zipper slider exhibit a non-superimposed relationship.

A continuous element slide fastener, which includes: a pair of support tapes, arranged in parallel, wherein a gap is formed between the pair of support tapes, each of the support tapes is formed with a first surface and a second surface which are oppositely arranged; and a pair of continuous-type coupling elements, respectively disposed at an inner edge of each of the second surfaces of the pair of support tapes, wherein each of the continuous-type coupling elements is formed with a connection surface and a fastening surface which are oppositely arranged, and the connection surface is formed with a first protrusion; when the slide fastener is in a coupled status, the highest positions of the first protrusions of the pair of continuous-type coupling elements are located in the gap, and the highest positions of the first protrusions are higher than the second surfaces.

The present invention provides a manufacturing method for manufacturing a fastener-attached product by sewing together a stringer member and a fastener-attached member. The manufacturing method includes preparing the stringer member including fastener elements in a coil shape, a support member, and a connecting part that connects an element row and a support body; performing a stringer attaching step in which the stringer member and the fastener-attached member are sewn together while the connecting part of the stringer member overlaps the fastener-attached member; and forming an attachment sewing part and sewing together a portion of the connecting part of the stringer member and the fastener-attached member with the attachment sewing part in the stringer attaching step. Thus, the fastener-attached product with flexibility improved compared to that in the related art can be provided.
