A zipping apparatus includes a zipper, a first connecting portion, a first channel, and a first rod. The zipper extending in a parallel axis includes crosslinking teeth and a tab movably coupled to the crosslinking teeth. The tab is configured to open and close the zipper. The first connecting portion is coupled to the zipper and extends in the parallel axis. The first channel is disposed along the first connecting portion and extends in the parallel axis. The first rod is configured to be positioned within the first channel, such that the first rod is configured to provide structure to the zipper assembly when positioned within the first channel.

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.

The present disclosure discloses a zipper comprising two zipper tapes and a zipper puller. The two zipper tapes are fastened or separated at the same time via the zipper puller; each zipper tape includes a fixing seat, a side barrier strip and a barbed strip, wherein the side barrier strip and the barbed strip are integrally formed on one side of the fixing seat, a slot is formed between the side barrier strip and the barbed strip, the barbed strip on one set of zipper tape fits into the slot on the other set of zipper tape, the end of the barbed strip away from the fixing seat is provided with barbs, the slot is provided with barb grooves, and the barbs on one set of zipper tape fit into the barb grooves on the other set of zipper tape. The present disclosure further reduces the production cost of zippers.

A switch clasp comprising a first part and a second part. The first part comprises a fastening structure adapted to secure the first part to a first item. The second part comprises a fastening structure adapted to secure the second part to a second item, said second part having an attractor adapted to attract a complementary attractor in the first part when the first and second parts are brought into engagement. At least one of said first part and second part including a sensor responsive to engagement and disengagement of the first and second parts to switch from a first condition to a second condition whereby a signal corresponding to the condition is output

The disclosure discloses a method for forming a rubber layer on a surface of a resin material. In the method, painting is first performed on the surface of the resin material to form a painting layer, using a paint to which a pigment has been added; then, rubber coating is performed to form a rubber layer on the painting layer. The method of the disclosure may be used in surface treatment of a fastener product. The disclosure further discloses a slide fastener, a buckle and a snap button using the method of the disclosure. The method of the disclosure may solve a conventional problem that a rubber coating is likely to fall off a resin surface, and the rubber on the surface of the resultant fastener product is less likely to fall off.
