  • Patent number: 9227390
    Abstract: This invention discloses a numbering and imprinting machine including a number cylinder, moving inker, first cleaning device, second cleaning device, inker position detector, and control device. The number cylinder includes at least one numbering device. The moving inker includes a number inker which supplies ink onto the number cylinder, and is movable between a printing position at which the number inker comes into contact with the number cylinder, and a retraction position at which the number inker separates from the number cylinder. The first cleaning device cleans the number cylinder. The second cleaning device cleans the number inker. The inker position detector detects the position of the moving inker. When the inker position detector detects that the moving inker is set at the printing position, the control device rotates the number cylinder, drives the number inker and controls cleaning operations by the first cleaning device and the second cleaning device.

  • Patent number: 8939078
    Abstract: An ink supply apparatus of a printing press includes at least one inking device. In the inking device, an ink fountain roller is rotatably supported. An ink fountain main body forms a space to store an ink together with an outer surface of the ink fountain roller. A guide member slidably supports the ink fountain main body and guides the ink fountain main body between a first position where the space is formed and a second position spaced apart from the ink fountain roller than the first position. A doctor including a blade is attached to a doctor holding member between the ink fountain main body and the ink fountain roller when the ink fountain main body is located at the second position. The blade abuts against the ink fountain roller and cleans the ink fountain roller.
