Abstract

La présente invention a trait à un mécanisme d'entraînement dans lequel une bande d'impression sans fin 54 passe autour d'une poulie d'entraînement 56 et d'une poulie folle 58, les poulies étant écartées pour laisser entre elles et devant un poste d'impression un chemin destiné au passage de la bande. La poulie d'entraînement 56 est soutenue en un point fixe alors que la poulie folle 58 est soutenue dans un berceau 92 par un dispositif souple 94, 96 pour permettre à la poulie folle 58 de se rapprocher ou de s'éloigner de la poulie d'entraînement 56. Ce mouvement est réalisé par un élement à came 130 ayant une position axiale fixe et pouvant tourner pour rapprocher ou éloigner le berceau de soutien de la poulie folle 92 de la poulie d'entraînement 56. Une paire de galets de guidage 140, 142 et une paire de leviers souples 144, 146 définissent les limites lors de la mise en place de la bande 54 sur les poulies.The present invention relates to a drive mechanism in which an endless printing belt 54 passes around a drive pulley 56 and an idler pulley 58, the pulleys being spread apart to leave between them and in front of a printing station a path for the passage of the tape. The drive pulley 56 is supported at a fixed point while the idler pulley 58 is supported in a cradle 92 by a flexible device 94, 96 to allow the idle pulley 58 to move closer or further away from the idler pulley. 'drive 56. This movement is achieved by a cam member 130 having a fixed axial position and rotatable to move the support cradle of the idler pulley 92 closer or further away from the drive pulley 56. A pair of guide rollers 140 , 142 and a pair of flexible levers 144, 146 define the limits when placing the band 54 on the pulleys.
