Abstract

L'invention concerne une semelle formée d'un seul tenant qui comprend une partie semelle large (1) et une partie semelle intermédiaire (3), une couche intermédiaire (2) étant agencée entre la partie semelle large (1) et la partie semelle intermédiaire (3), et la partie semelle large (1), la couche intermédiaire (2) et la partie semelle intermédiaire (3) étant formées d'un seul tenant. La semelle formée d'un seul tenant est formée par les étapes consistant à placer la partie semelle large (1), la partie semelle intermédiaire (3) et la couche intermédiaire (2) dans un moule et, ensuite, à coller la partie semelle large (1), la partie semelle intermédiaire (3) et la couche intermédiaire (2) dans un état sous vide à une température comprise entre 120 et 130 degrés centigrades ; en raison du fait que la partie semelle large (1), la couche intermédiaire (2) et la partie semelle intermédiaire (3) sont formées d'un seul tenant pour éviter l'utilisation d'une couche de colle, la semelle formée d'un seul tenant présente les avantages d'un assemblage ferme, d'une faible possibilité de séparation de la partie semelle intermédiaire (3) et de la partie semelle large (1), de ne pas être dangereuse pour le corps humain et de ne créer aucune pollution environnementale, de permettre une économie de main d'œuvre, une amélioration de l'efficacité de production et une réduction efficace des coûts.
