Title (EN) TREAD MANUFACTURING METHOD
(FR) PROCEDE DE FABRICATION DE BANDE DE ROULEMENT
Abstract:
(EN) The invention relates to a method for manufacturing all or part of a tread (2) of a mounted assembly (1) designed to be mounted on a motor vehicle, comprising the following steps: - a step of constructing (103) at least a portion of a tread depending on laying characteristics on a tread bearing surface, said construction step being carried out by adding material by additive manufacturing carried out on said tread bearing surface; - the step of constructing (103) the tread is carried out on the mounted assembly (1), the latter being mounted on the motor vehicle.
(FR) Procédé de fabrication de tout ou partie d'une bande de roulement (2) d'un ensemble monté (1) adapté pour être monté sur un véhicule automobile, comprenant les étapes suivantes: - une étape de construction (103) d'au moins une portion d'une bande de roulement en fonction de caractéristiques de pose sur une surface porteuse de bande de roulement, ladite étape de construction étant réalisée par ajout de matière par fabrication additive mise en œuvre sur ladite surface porteuse de bande de roulement; - l'étape de construction (103) de la bande de roulement est réalisée sur l'ensemble monté (1), celui-ci étant montésur le véhicule automobile.
