Abstract
A slider having an outer guide that closes a zipper by sliding movement of the slider and an inner guide that opens the zipper by the sliding movement and is formed revolvable on the outer guide. A method for supplying sliders provides sliders that are not entangled with each other and are not clogged when supplied with the inner guide revolved to the outside. The slider has a groove formed by the inner guide protruding upwards from the upper surface of a slider body. A flat guide plate disposed between a slider supplying machine and a slider assembling machine engages with the groove so that the upper surface directs in a vertical direction and, at the same time, side surfaces of adjacent sliders support the slider facing each other in a hanging down condition, and align and guide them in a line in a fixed direction.
Claims22
A method for supplying sliders to be assembled in plastic zippers in order to open and close the plastic zippers, each of the zippers having a pair of male and female hooks formed on surfaces of plastic films, and each of which sliders comprises an outer guide, riding on the plastic zipper so as to constitute a slider body and serving to close the plastic zipper by means of sliding movement of the slider, and an inner guide, serving to close the plastic zipper by means of sliding movement of the slider, said inner guide is disposed on the slider body in such a manner that it protrudes outwards from the slider body and that it is revolvable around an axis which is crossed at a right angle to the plastic zipper, the method comprising:
- supplying the sliders from a slider supplying machine, the sliders having a groove extending in parallel with said axis and formed by the inner guides protruding upwards from upper surfaces of the slider bodies,
- engaging said groove of the supplied sliders with a flat guide plate, which is disposed between the slider supplying machine and an assembling machine, such that the upper surfaces direct in a vertical direction and, at the same time, the sliders hang down in a vertical direction and are supported by the flat guide plate in a condition wherein side surfaces of adjacent sliders are adjacent to each other in order to align and guide the sliders in a constant direction.
A system for supplying sliders to be assembled in plastic zippers in order to open and close the plastic zippers, each of the zippers having a pair of male and female hooks formed on surfaces of plastic films, and each of which sliders comprises an outer guide, riding on the plastic zipper so as to constitute a slider body and serving to close the plastic zipper by means of sliding movement of the slider, and an inner guide, serving to close the plastic zipper by means of sliding movement of the slider, said inner guide is disposed on the slider body in such a manner that it protrudes outwards from the slider body and that it is rotatable around an axis which is crossed at a right angle to the plastic zipper, the system comprising:
- a slider supplying machine configured to supply the sliders, the sliders having a groove extending in parallel with said axis and formed by the inner guides protruding upwards from upper surfaces of the slider bodies;
- a flat guide plate configured to engage said groove of the supplied sliders such that the upper surfaces direct in a vertical direction and, at the same time, the sliders hang down in a vertical direction and are supported by the flat guide plate in a condition wherein side surfaces of adjacent sliders are adjacent to each other in order to align and guide the sliders in a constant direction;
- and
- an assembling machine;
- wherein the flat guide plate is disposed between the between the slider supplying machine and the assembling machine.
