The new dispensing roll of deadfold stickers comprises a length of flexible carrier tape having a low adhesion surface and a multiplicity of flexible deadfold stickers releasably adhered to the low adhesion surface for easy removal therefrom. Each deadfold sticker comprises a laminate of pliable layers and at least two deadfold wires in spaced parallel alignment embedded in the laminate in a direction transverse to the length of the carrier tape. The carrier tape with releasably adhered deadfold stickers is wound upon itself in the dispensing roll. The dispensing roll is used in automatic machinery to form mouth-foldable deadfold reclosable bags; and the preferred reclosures are those having three creases of fold line formed by two folding steps.

Le nouveau rouleau distributeur d'autocollants de fermeture comprend une longueur de ruban support souple à surface à faible adhésivité et une multiplicité d'autocollants de fermeture souples collés sur le ruban support et faciles à retirer au moment de l'emploi. Chaque autocollant est constitué d'un ensemble feuilleté de couches souples et d'au moins deux fils métalliques de pliure noyés en alignement parallèle dans le feuilleté, dans une direction transversale par rapport au ruban support. Le ruban support portant les autocollants de fermeture est enroulé sur lui-même en un rouleau de distribution. Ledit rouleau est utilisé en association avec des machines automatiques pour former des sacs à embouchure pliante refermable; et les fermetures privilégiées sont celles qui comportent trois plis, formés par deux étapes de pliage
