Abstract

L'invention concerne une installation pour la production, largement automatisée, de semelles de chaussures à usage orthopédique, comprenant un dispositif de mesurage de la plante du pied, un dispositif de production de supports orthopédiques pour chaussures, réalisée sur la base des résultats des mesures, ainsi qu'un système de traitement de données recevant les résultats des mesures du dispositif de mesurage, avec retouchage, par exemple lissage éventuel, et les transformant en données de commande pour le dispositif de production. Le dispositif de mesurage effectue un balayage, sensiblement ligne par ligne, de la plante du pied, ce qui fournit une topographie de la plante du pied sous la forme de coupes hypsométriques. A cet effet, un ou plusieurs détecteurs électromécaniques (13) se déplacent dans le sens longitudinal au-dessus de la plante du pied, de manière à suivre les variations en hauteur. Le mouvement des détecteurs (13) est converti en signaux électriques par l'intermédiaire d'un potentiomètre linéaire (25). Le dispositif de production présente une tête de façonnage, par exemple une fraise, qui est déplacée suivant un tracé hélicoïdal au-dessus de l'ébauche des supports des chaussures. Les données relatives à la hauteur de la fraise sont déterminées, de façon largement automatisée, par le système de traitement de données à partir des résultats fournis par le dispositif de mesurage.
