Abstract
A method and apparatus for manufacturing reclosable bags having slide zippers on a form-fill-seal machine is provided. In a first embodiment the sliders are preapplied to the zipper and the bags are made using conventional form-fill-seal techniques. In a second embodiment a coil of sliders is fed into the form-fill-seal machine where the sliders are applied to the zippers by an insertor mechanism. In a third embodiment a magazine of individual or connected sliders is used to feed a slider insertor mechanism which then applies the sliders to the interlocked zippers. In a fourth embodiment bulk sliders are introduced into a vibratory feeding bowl which then orients and feeds the sliders to the slider insertor mechanism.
