Abstract
An assembly of sliders for zippers for plastic bags and the like and the accumulation of the sliders for use in form, fill and seal machines is disclosed. The sliders are oriented and mechanically or adhesively joined into chains. Mechanical assembly of sliders may be accomplished by snapping sliders together or slideably mounting sliders on a strip. Sliders may be adhesively assembled together by taping, welding, gluing, or melting the sliders. Sliders and chains of sliders are accumulated in cartridges, carriers, coreless rolls, spools or trays which are then connected to form, fill and seal machines for attachment of the sliders to a zipper and attachment of the zipper with a slider to bags.
