Abstract

La présente invention concerne une imprimante pour pneumatique qui est apte à exécuter une impression, avec une précision supérieure lorsqu'elle est comparée à une imprimante pour pneumatique classique, sur un pneumatique auquel aucune roue n'est fixée. L'imprimante pour pneumatique (10) exécute l'impression (10) sur un flanc d'un pneu et comprend : un support de pneumatique (30) sur lequel est placé un pneu (93) avec une paire de flancs (93a) du pneu (93) orientés verticalement dans le sens vertical indiqué par une flèche (10a); un moteur DD (29) pour faire tourner le support de pneumatique (30) dans le sens de la circonférence du pneu (93); et une tête à jet d'encre (53) pour exécuter une impression sur le flanc supérieur (93a) de la paire de flancs (93a) du pneu (93) placés sur le support de pneumatique (30). L'imprimante pour pneumatique est adaptée de telle sorte que le support de pneumatique (30) soutienne le flanc inférieur (93a) de la paire de flancs (93a) à partir du dessous dans le sens vertical.
