  • Patent number: 7771336
    Abstract: In a variable cut-off length type rotary printing machine, to perform processes such as a process of folding a cut-off sheet with a high degree of accuracy, a folding machine includes a cut-off unit capable of varying and cutting a cut-off length of a web fed from a printing machine of the rotary printing machine, and a processor (such as a folder, etc.) for processing a sheet 10a cut off by the cut-off unit. Between the cut-off unit 50 and the processor, the folding machine further includes a first belt conveyor for conveying the sheet at a speed equal to the web, and a second belt conveyor for receiving the sheet from the first belt conveyor at a speed approximately equal to the sheet conveying speed of the first belt conveyor, then varying the conveying speed to a speed approximately equal to the sheet conveying speed of the processor, and delivering the sheet to processor.

  • Publication number: 20080202368
    Abstract: An ink supplying unit supplies a water-based ink having a predetermined water content set in advance. An ink form roller receives the water-based ink from the ink supplying unit. A plate cylinder is in contact with the ink form roller, and receives the water-based ink from the ink form roller. A water-content decreasing unit decreases the water content of the water-based ink on the ink form roller.

  • Publication number: 20080115682
    Abstract: A cleaning device that cleans an ink-supply path of a printer including a plurality of cylinders that constitute the ink-supply path. The cleaning device supplies cleaning solution from a cleaning nozzle to an ink-transfer cylinder in the state where the ink-transfer cylinder is not in contact with an ink-source cylinder, and a blanket cylinder is not in contact with a recording medium. After the cleaning solution is supplied to all the cylinders, a cleaning-solution collecting cylinder is brought into contact with an inking cylinder to collect waste cleaning solution therefrom. A cleaning-solution removing blade removes the waste cleaning solution from the cleaning-solution collecting cylinder.

  • Patent number: 5787812
    Abstract: An object of the present invention is to provide an economical and highly operable blanket mounting apparatus in which the width of a cylinder gap on a blanket cylinder is further decreased to eliminate a printing trouble such as shock-streak and to shorten the non printing length. To achieve this object, a flat bar 15a, 15b is installed at each end of a blanket 2, a notch 16 with the same size as that of the leading edge flat bar 15a is formed in a cylinder gap 3, the leading edge flat bar 15a of the blanket 2 is inserted along a leading edge opening 3a of the notch 16, and a tail edge 2b of the blanket 2 to which a flat bar 15b is fixed is reeled by a reel bar 14, by which the cylinder gap opening is blocked by the leading edge flat bar 15a.
