A method and an apparatus for automatically feeding slider-zipper assemblies to a station where the slider-zipper assemblies can be attached to bag material (8) such as thermoplastic film. The apparatus includes a slider guide (2) having a channel running the length thereof. The channel has a cross section that allows passage therethrough of sliders (20) slidably mounted to a tape of connected slider-zipper assemblies. A tape drive mechanism is located at the outlet of the slider guide. The tape drive mechanism includes a pair of rollers (36,38) that form a nip therebetween. The zipper flanges of the tape are threaded through the nip. The rollers have respective grooves that form a space (41) for passage of the sliders as the tape is advanced by the rollers. <IMAGE> |
