Process and system for removing printing in metallic packages used in drinks, food and other applications in general, comprising the removal of ink before the cure thereof, by means of spray with ink remover liquid and non abrasive friction. Preferably, said liquid is an alkaline aqueous solution, which is sprayed onto the package surface simultaneously with the friction thereof with a soft and non abrasive element. In a preferred embodiment, said friction results in the rotation of the package around the longitudinal axis thereof, which is mounted on a rotative support, and the soft non abrasive element in contact with the surface thereof keeps motionless.

L'invention porte sur un procédé et un système pour retirer une impression dans des boîtes métalliques utilisées pour des boissons, un aliment et d'autres applications en général, comprenant l'élimination de l'encre avant la cuisson de celles-ci, au moyen d'une pulvérisation d'un liquide d'élimination de l'encre et d'un frottement non abrasif. De préférence, ledit liquide est une solution aqueuse alcaline qui est pulvérisée sur la surface de la boîte simultanément avec le frottement de celle-ci avec un élément doux et non abrasif. Dans un mode de réalisation préféré, ledit frottement conduit à la rotation de la boîte sur son axe longitudinal qui est monté sur un support rotatif, et l'élément doux non abrasif en contact avec la surface de celui-ci reste immobile.
