Woven and knit substrates having juxtaposed notches with finished edges are disclosed. Such substrates can be used as opposed fastener tapes and fastener elements can be formed, woven, or otherwise added to the opposed fastener tapes in a known fashion. The notched fastener tapes permit the resulting slide fastener to be curved in-plane without buckling either of the opposed the fastener tapes out-of-plane. The finished edges maintain structural integrity of the woven or knit substrates, in stark context to prior art substrates having cut notches. Also disclosed are panelized substrates having curved apertures and incorporating disclosed slide fasteners.

Zippers, including a device for replacing a malfunctioning zipper. In some examples, the zipper includes a plurality of attaching means that fit over the teeth of a malfunctioning zipper. In some further examples, the zipper may function to repair a tear in the material of an item.

A molded-teeth slide fastener tape for use in a slide fastener assembly includes a woven portion and a plurality of resin-based teeth. The woven portion includes a cord arranged along an edge thereof and a plurality of spaced-apart perforations, disposed adjacent to the cord, which pass completely through the woven portion. Each of the plurality of resin-based teeth is integrally molded to the woven portion along the cord. Each molded tooth encompasses at least a portion of at least one of the spaced-apart perforations so that each molded tooth extends through the at least one of the spaced-apart perforations and fully around a cross-sectional shape of the cord.

A marking device performs a marking process onto a long object. The marking device includes a driving source and a marking unit that performs a circular motion in accordance with a driving force supplied from the driving source. While the long object is being transferred, marks are applied onto the long object in accordance with the circular motion of the marking unit. An extent of interference by the marking unit to the transfer of the long object is reduced, thus facilitating higher speed transfer of the long object.

A method for sewing a slide fastener includes forming end edge portion needle drop points in at least two positions, within an overlapped portion in which the work piece is folded, within a range more toward a tip side of an end edge portion of the work piece than half of an overlapped width, and within a range on an inner side of a width of a leg portion of an interlocking element. Sewing is performed with sewing thread passing from a head portion needle drop point to the end edge portion needle drop point of one end portion and sewing thread passing from the end edge portion needle drop point of another end portion to the head portion needle drop point of an adjacent interlocking element each passing either side of the leg portion.
