Patent

CA 2385694

A slider-operated fastener (10) comprises first and second opposing tracks (12, 14) including respective first and second interlocking profiles (16, 18) and respective first and second fins (20, 22) extending downward from the respective first and second profiles (16, 18). The first and second fins (20, 22) are sealed to each other by a plurality of spaced preseals (28). After generating each preseal (28), a notch (38) is formed in the profiles and upper portions of the fins (20, 22) at the generated preseal (28). To install a slider (40) is initially positioned within the respective notch (38) and then threaded onto the fastener (10) in response to relative movement of the slider (40) and the fastener. Either before or after the steps of forming each preseal (28) and respective notch (38) and installing the respective slider (40), the fastener (10) is attached to a moving web (50) of plastic film (52). The fastener-carrying web (50) is later folded and sealed to form individual plastic bags (80).

Un fermoir actionné par curseur (10) comprend un premier et un deuxième guides opposés (12, 14) comprenant un premier et un deuxième profils interverrouillables respectifs (16, 18) ainsi qu'une première et une deuxième ailettes (20, 22) faisant saillie vers le bas depuis les premier et deuxième profils respectifs (16, 18). Les première et deuxième ailettes (20, 22) sont scellées l'une à l'autre au moyen de plusieurs joints préalables espacés (28). Après la formation de chaque joint préalable, on forme une encoche (38) dans les profils et les parties supérieures des ailettes (20, 22), au niveau du joint préalable qui vient d'être créé (28). Pour installer un curseur (40) dans le fermoir, le curseur est d'abord placé dans l'encoche correspondante (38) puis enfilé sur le fermoir (10) en réponse à un mouvement correspondant du curseur (40) et du fermoir. Soit avant, soit après la formation de chaque joint préalable (28) et de l'encoche correspondante (38) ainsi que le montage du curseur correspondant (40), le fermoir (10) est attaché à une bande mobile (50) d'un film plastique (52). La bande (50) sur laquelle repose le fermoir est ensuite repliée et scellée de manière à former des sacs plastiques individuels (80).
