  • Article with Slide Fastener and Method for Producing Article with Slide Fastener
    Publication number: 20180192748
    Abstract: There is provided an article with a slide fastener affixed thereto. Each of a pair of element members has a plurality of single elements made of a synthetic resin and fixedly integrated and connected to at least one flexible connecting string-shaped member at an equal interval. A slider is formed with an element guide path between upper and lower blades. A fastener-attached member forms an opening and closing part of the article. The pair of element members are directly sewn to a first surface of the fastener-attached member by sewing threads. The element members and the fastener-attached member are inserted into the element guide path of the slider.

  • Method for manufacturing molding hook and loop fastener
    Patent number: 10016023
    Abstract: Provided is a molding hook and loop fastener, in which a barrier erected near left and right side edges of a substrate includes at least two rows of vertical wall arrays, and the vertical wall array includes a plurality of vertical walls disposed alternately. Between the two adjacent, rows of the vertical walls disposed alternately, each of the vertical walls disposed on one row is connected to two vertical walls disposed on the other row via a connecting part, and the connecting part connects one end portion of one vertical wall disposed on the adjacent row and the other end portion of the other vertical wall. Due to this, in the molding hook and loop fastener an outer side and an inner side of the barrier can be divided by the vertical wall array and the connecting part, and flexibility of the molding hook and loop fastener can be improved.

  • Slide fastener slider
    Patent number: 9993049
    Abstract: There is provided a slide fastener slider. A pull tab has a rotatable region including laid-down positions and a stood-up position. Within the rotatable region of the pull tab, a locking pawl is elastically deformed to move a cover portion, and a pawl portion is arranged to be inserted into and removed from an element guide passage in accordance with movement of the cover portion. When the pull tab is completely laid down toward the shoulder mouths and rear mouth relative to the slider body, the pull tab has respective regions in which the pull tab is rotatable over a predetermined angle without exerting any load on the locking pawl.

  • Fastener Element, Fastener Stringer, and Slide Fastener
    Publication number: 20180132573
    Abstract: 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.
