Abstract

Dans les fermetures à glissière selon l’invention (1, 21, 31, 41),la couture des éléments de la fermeture (10, 10', 32, 42, 52) est effectuée avec un premier fil de couture (8) pour coudre les premières et deuxièmes pattes (11, 12, 61, 62) à une bande de la fermeture (2)et avec un deuxième fil de couture (9) pour coudre les deuxièmes pattes (12, 62) à la bande de la fermeture (2)du côté plus proche des têtes d’engrènement (13, 63) que le premier fil de couture(8). La couture des deuxièmes pattes (12, 62) est effectuée avec une couture à double point effectuée avec le fil d’aiguille (9a) et le fil de dessous (9b) du deuxième fil de couture (9). Des gorges de retenue (15, 15', 65) permettant de recevoir et de retenir le fil de dessous (9b) en une position plus proche de la bande de la fermeture (2) que les surfaces (12a, 62a) des deuxièmes pattes (12, 62) situées en regard des premières pattes sont formées sur les surfaces (12a, 62a) situées en regard des premières pattes. Lorsque les rangées d’éléments (3) gauches et droits s’engrènent, elles s’engrènent avec stabilité, l’interférence des têtes d’engrènement (13, 63) d’un élément de la fermeture (10, 10', 32, 42, 52) avec une partie traversante (7) étant réduite par la couture à double point du fil de couture (9)prévu pour coudre l’autre élément de la fermeture (10, 10', 32, 42, 52). En outre, il est ainsi possible d’assurer un excellent camouflage même lorsque la bande de la fermeture (2) est soumise à une force de traction latérale une fois engrenée, en évitant l’exposition des rangées d’éléments gauches et droits (3) depuis la zone située entre les éléments de la partie recourbée en forme de U (2c) de la bande de la fermeture (2).
