Title
(EN) ZIPPER AND ZIPPER ARRANGEMENTS AND METHODS OF MANUFACTURING THE SAME
(FR) FERMETURE A GLISSIERE, AGENCEMENTS ET PROCEDES DE FABRICATION DE CETTE FERMETURE
Abstract
(EN)
A zipper arrangement for use in manufacturing thermoplastic bags that includes a zipper and at least one slider. The zipper includes first and second opposing tracks (26, 32). The first track (26) has a first profile (28) and the second track (32) has a second profile (34). The first and second profiles are releasably engageable to each other. The first track has one or more spaced primary notches (12a) interrupting the first profile. At least one slider (16b) is inserted onto the first profile via a respective one of the primary notches (12b). The slider is adapted to engage and disengage the first and second profiles in response to movement along the zipper. The second track may have one or more spaced primary notches (12b) interrupting the second profile. The spaced primary notches of the second track are generally aligned to respective ones of the primary notches of the first track. At least one slider is inserted onto the aligned pairs of primary notches via a respective one of the aligned notches.

L'invention concerne l'utilisation d'un agencement de fermeture à glissière, dans la fabrication de sacs thermoplastiques comprenant une fermeture à glissière et au moins un curseur. La fermeture comprend des première et seconde glissières opposées (26, 32), la première glissière (26) présentant un premier profil (28) et la seconde (32) un second profil (34). Ces premier et second profils peuvent s'emboîter l'un dans l'autre, de manière amovible. La première glissière comporte une ou plusieurs premières encoches (12a), espacées, créant une rupture dans le premier profil, au moins un curseur (16b) pouvant s'insérer sur le premier profil, en passant par l'une de ces premières encoches (12b). Le curseur est conçu pour coupler et se désaccoupler des premier et second profils en réponse à son déplacement le long des glissières. La seconde glissière peut comporter une ou plusieurs premières encoches (12b), espacées, créant une rupture dans le second profil. Les premières encoches, espacées, de la seconde glissière, sont généralement respectivement alignées sur les premières encoches de la première glissière, au moins un curseur pouvant s'insérer sur les paires de premières encoches alignées, en passant par l'une de ces encoches.
