À cet effet, l'invention propose un dispositif de traitement de surface qui comprend au moins : un boîtier d'injection cylindrique pourvu d'une section d'ouverture principale et d'une section d'ouverture auxiliaire; un joint d'étanchéité adsorbant annulaire qui scelle l'espace entre le boîtier d'injection et la surface d'un objet; une buse qui pulvérise des substances de traitement de surface vers la surface d'un objet; un mécanisme pour déplacer horizontalement la buse qui déplace la buse horizontalement de manière alternative sur toute la surface de l'objet; une courroie plate servant à recouvrir l'ouverture de la section d'ouverture auxiliaire; et un moyen de génération de vide qui permet de décompresser l'espace délimité par la surface de l'objet, le boîtier d'injection, le joint d'étanchéité adsorbant et la courroie plate. Un moyen de déplacement, de type roue mobile, est présent à l'intérieur du dispositif, le mécanisme qui permet de déplacer la buse horizontalement étant conçu de façon que la buse est déplacée horizontalement dans une direction qui croise la direction de déplacement du dispositif de traitement de surface, et la buse étant également déplacée de manière alternative dans une direction qui croise la direction dans laquelle la buse se déplace horizontalement.
