Abstract: Method and apparatus of manufacturing color metal zipper are disclosed. The method includes washing half-finished metal zipper; overlaying a thin film on the upper surface of half-finished metal zipper; feeding color transfer paper; overlaying the half-finished metal zipper on the color transfer paper and positioning same; intermittently advancing the overlaid half-finished metal zipper and the color transfer paper; heating and pressing the overlaid half-finished metal zipper and the color transfer paper in an interval when the advancing stops for uniformly transferring color of the color transfer paper to a portion of the half-finished metal zipper; intermittently advancing the half-finished metal zipper and the color transfer paper again; separating the finished color metal zipper from the color transfer paper while intermittently advancing; and cooling and storing the finished color metal zipper and color transfer paper.

Abstract: A zipper having its tab or slide incorporating an RFID device is disclosed. The RFID device includes an IC disposed on a central portion of a recess of the tab or slide, an antenna in the form of a plurality of closely engaged concentric miniature enamelled wire conductors secured on a zone defined between projections spaced around a center of the recess and a peripheral flange of the recess, and two connections each electrically interconnected the IC and the antenna. In one embodiment, the tab has a ring for putting on an object. The concealed RFID device can be protected. Also, it may not detract from the zipper's external appearance.

Abstract: Method and apparatus of manufacturing color plastic zipper are disclosed. The method includes feeding a continuous row of half-finished plastic zipper, feeding a continuous strip of color transfer film, overlaying the half-finished plastic zipper and the color transfer film and positioning same, intermittently advancing the overlaid half-finished plastic zipper and the color transfer film, heating and pressing the overlaid half-finished plastic zipper and the color transfer film in an interval when the advancing stops for uniformly transferring color of the color transfer film to a portion of the half-finished plastic zipper, advancing the half-finished plastic zipper and the color transfer film again, separating the finished color plastic zipper from the color transfer film while intermittently advancing, and cooling the finished color plastic zipper and the color transfer film. The invention has advantages of high efficiency, high yield, and having a low manufacturing cost.
