Abstract (en)

An apparatus for feeding ink from an ink pan (11) to a vibration roller (16), incorporated in a printing press, such as an offset press or a letter press, including a dip roller (13) rotatably in contact with an ink (12) received in the ink pan (11), a doctor blade (14) for forming an ink layer (2a) having a predetermined thickness on the surface of the dip roller (13), a vibration roller (16) disposed downstream of the dip roller (13), and a plurality of small rollers (15a through 15g) interposed between the dip roller (13) and the vibration roller (16) and periodically movable to be alternately in contact with either the surface of the dip roller (13) or the surface of the vibration roller (16). The reciprocation of each respective small rollers (15a through 15g) is controlled independently from the other small rollers (15a through 15g), through a drive mechanism comprising a solenoid (14), by a program memorized in a microcomputer so that the contact time period of the small roller (15a through 15g) in a cycle varies in accordance with a variation of the ink consumption in the widthwise direction of the press.
