Abstract: Plate cylinder driving devices of a printing machine are provided with a drive shaft driving the plate cylinder, a drive helical gear fixed to the drive shaft, and an anti-backlash helical gear rotatably connected to the drive shaft and is biased by at least a spring towards a direction for preventing backlash. Both the drive helical gear and the anti-backlash helical gear are engaged with the main gear, and a plate provided with plural holes accommodating rollers is provided between the drive helical gear and the anti-backlash helical gear. Friction between the anti-backlash gear and the drive gear is reduced by a simple mechanism in the plate cylinder driving devices in a printing machine.

Abstract: A printing press makes an ink reservoir between an ink fountain and an ink fountain roller and supplies ink to the plate cylinder via a ductor roller advancing and retracting towards and from the ink fountain roller. The printing press is provided with the ink fountain, a base supporting the ink fountain, a slide mechanism sliding the ink fountain along the base in order to control the clearance between the tip of the ink fountain and the ink fountain roller, a cleaner removing the ink from the ink fountain roller, an advancement and retraction mechanism for advancing and retracting the cleaner between a contact position to the ink fountain roller and a non-contact position, and a controller. The controller controls the slide mechanism and the advancement and retraction mechanism, enlarges the clearance in order to pass the dirt with the ink through the clearance, and makes the cleaner in contact with the ink fountain roller to remove the dirt with the ink.
