Abstract: Fastener stringer includes a fastener tape provided with a fastener element; and a stop part arranged at an end of the fastener tape. The stop part includes: a magnetic body; an encapsulating member encapsulating the magnetic body; and an injection-molded portion that at least partially covers or surrounds the encapsulating member encapsulating the magnetic body. At least the encapsulating member hinders heat from being transferred to the magnetic body while the injection-molded portion is formed.

Abstract: 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.
