Abstract

L'invention concerne une courroie transporteuse (1) qui comprend un maillon (21) qui s'engage avec une première tige (11) de façon à pouvoir tourner et de façon à pouvoir se déplacer dans la direction du déplacement (la gauche sur la figure) et qui est fixé par les deux extrémités d'une deuxième tige (12) près du côté arrière (côté droit sur la figure) de la première tige (11), et un fil métallique (31) qui relie la première tige (11) et la deuxième tige (12) selon un cheminement en spirale. Un excès de métal de soudure (17a) est formé, par soudure, sur le côté avant (côté gauche sur la figure) entre la surface interne du maillon (21) (la surface sur le côté supérieur sur la figure) et la deuxième tige (12). Le bord (65) sur les deux extrémités du fil métallique (31) est formé de façon à être positionné sur le côté arrière. Ainsi, le bord (65) du fil métallique (31) n'entre pas en contact avec l'excès de métal de soudure (17a) quand la courroie transporteuse (1) tourne et se déplace. L'excès de métal de soudure (17a) ne s'abîme donc pas et la fiabilité de la courroie transporteuse (1) est améliorée.
