An item may be provided with a body that forms an enclosure. The body may have a body portion that opens and closes along a seam. An elongated magnetic fastener may run along the seam. The magnetic fastener may have first and second strips of elastomeric material on opposing sides of the seam. Magnetic interlocking elements may be partially embedded in the first and second elastomeric strips. The fastener may be formed by injecting uncured elastomeric material having unmagnetized magnetic particles into a mold. While in the mold, a magnetic field may be applied to magnetize the magnetic particles and to align the magnetic particles into magnetized structures. After forming the magnetized structures within the elastomeric material, the elastomeric material may be cured. Once removed from the mold, portions of the elastomeric material may be removed to expose the magnetized structures, which may subsequently be shaped into interlocking fastener elements.

A fastening element may comprise a first panel and the second panel. The first panel may have a first longitudinal edge and the second panel may have a second longitudinal edge. The second longitudinal edge may be spaced from the first longitudinal edge to form a curvilinear gap. The fastening element may comprise a fastening mechanism coupled to the first longitudinal edge using an adhesive. The fastening mechanism may comprise a zipper tape and a plurality of teeth. The zipper tape may be configured by applying the adhesive on at least a portion of the zipper tape and cutting through the adhesive and zipper tape to define a plurality of cut-outs in the zipper tape.

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.

The disclosure provides a pull and a manufacturing method of the pull, which can mount an electronic component inside a handle part without damaging the electronic component and have favorable electronic functions. The pull of the disclosure is to be mounted on a slider for a slide fastener, and includes a ring part, an insertion part, the handle part, and the electronic component. The ring part is to be mounted on the slider. The insertion part is connected to the ring part for receiving an injection material. The handle part is formed sequentially on the insertion part by the injection material. The electronic component is mounted inside the handle part in a process in which the handle part is formed sequentially on the insertion part by the injection material.

Provided is a fastener stringer including a row of metal elements having a plating film formed with improved thickness uniformity without waste, even if the elements are not electrically connected to each other in advance. For each of ten adjacent metal elements of the fastener stinger, 0.6D.sub.1/A.sub.12.0 is satisfied in which A.sub.1 represents an average value of thickness of the plating film for the ten metal elements at element center on either one main surface side of the fastener tape, and D.sub.1 represents thickness of the plating film for each of the metal elements at the element center on the one main surface side of the fastener tape.

A slider may include a slider body, a pull-tab attachment portion provided at the slider body, and a resin-made pull tab attached to the pull-tab attachment portion. The pull tab may include an axial portion and a pair of bars extending from respective ends of the axial portion. The pull-tab attachment portion may include a pair of claws that axially support the axial portion of the pull tab. Each claw may be held by and between the respective paired bars while the pull tab pivots. A width of a terminal end of each claw in an axial direction of the axial portion may be less than a width of a base end of each claw in the axial direction.
