Abstract
Methods are provided for making slider-operated fasteners for use in reclosable plastic bags using at least a double index and dual unit operations. The methods involve forming two preseals, forming two notches within the preseals, applying two sliders into the previously formed notches, and applying two end stops proximate the previously applied sliders by having the various stations perform their respective functions, either simultaneously or at generally the same time, on different parts of the fastener spaced approximately at a double index. Also provided are methods of producing finished bags by applying the slider-operated fastener to a flat web of plastic film and conveying the web to a vertical or a horizontal form-fill-seal machine.
