Method and apparatus for manufacturing reclosable bags

摘要

A method and apparatus for manufacturing reclosable bags having slide zippers (54) on a form-fill-seal machine (100) is provided. In a first embodiment (Fig. 5) the sliders (54) are pre-applied to the zipper (10) and the bags are made using conventional form-fill-seal techniques. In a second embodiment (Fig. 8) a coil of sliders (128) is fed into the form-fill-seal machine (100) where the sliders (54) are applied to the zippers (10) by an insertor mechanism. In a third embodiment (Fig. 9) a magazine (134) of individual or connected sliders (54) is used to feed a slider insertor mechanism (130) which then applies the sliders (54) to the interlocked zippers (10). In a fourth embodiment (Fig. 10) bulk sliders (54) are introduced into a vibratory feeding bowl (136) which then orients and feeds the sliders (54) to the slider insertor mechanism (130).
