Abstract

L’invention concerne un procédé de nettoyage d’une sculpture d’un pneumatique identifié endommagé en cours de rechapage, le procédé mis en œuvre par au moins un processeur comprenant un module de traitement qui applique, à au moins un réseau neuronal, les données représentatives des images capturées de la sculpture du pneumatique identifié. L’invention concerne aussi un procédé de rechapage comprenant le procédé divulgué. L’invention concerne en outre un système de nettoyage automatique permettant le nettoyage d’une sculpture d’un pneumatique identifié en cours de rechapage. Figure pour l’abrégé : Fig. 11The invention relates to a method for cleaning the tread pattern of an identified damaged tire during retreading. The method is implemented by at least one processor comprising a processing module that applies representative data from captured images of the identified tire tread pattern to at least one neural network. The invention also relates to a retreading method comprising the disclosed method. The invention further relates to an automatic cleaning system for cleaning the tread pattern of an identified tire during retreading. Figure for the abstract: Fig. 11
