Method for suppluing sliders

Method for supplying sliders which are 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, and when the sliders, which are capable of being arranged at a predetermined position where they function as inner guide, are supplied from a slider supplying machine to a slider assembling machine by means of the revolving motion, the sliders, which are being supplied, are provided with a groove extending in parallel with said axis and formed by the inner guides protruding upwards from the upper surfaces of the slider bodies, a flat guide plate, which is disposed between the slider supplying machine and the assembling machine, engages with said groove so that the upper surfaces direct in a vertical direction and that at the same time, the sliders hung down in a vertical direction are supported in a condition wherein side surfaces of the adjacent sliders are adjacent to each other in order to align and guide the sliders in a constant direction.
