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.

L'invention concerne un ensemble de curseurs pour sacs plastiques, par exemple, et l'assemblage de ces curseurs de manière à pouvoir les utiliser avec des machines de formage-remplissage-scellage. Les curseurs sont orientés et assemblés en chaîne mécaniquement ou par collage. L'assemblage mécanique des curseurs peut s'effectuer par encastrement ou par montage latéral sur une courroie. L'assemblage par collage des curseurs comprend le rubanage, le soudage, l'encollage ou la fusion. Les curseurs et les chaînes de curseurs s'accumulent en cartouches, en chariots, en rouleaux à âme creuse, en bobines ou en plateaux qui sont ensuite connectés à des machines de formage-remplissage-scellage de manière à fixer les curseurs à des fermetures à glissière et à fixer ces fermetures à glissière munie de curseurs à des sacs.
