PURPOSE:To prevent a sheet from vibrating, stabilizing it, and improve a degree of printing quality, by installing a sheet holding device such as a suction table or the like, in a running part performing intermittent feed for a continuous sheet, and making it hold the sheet all the time. CONSTITUTION:A sheet 3 drawn out of a sheet roll 1 by a pull roll part 11 is printed with ink of respective colors at plural printing parts 10 and runs intermittently. The sheet 3 passing through the pull roll part 11 is rolled on a winder 13, forming a roll 12. The pull roll part 11 is constituted of a suction roll 26 and a drug roll 27 attaching a pull member 22 to a part of the circumference, and with the presence of the pull member 22, makes the sheet 3 intermittently run. At an intermittent running part of the sheet 3, there is provided with a sheet holding device 28 of a suction table or the like. with this constitution, vibrations and noises in the sheet produced at the time of stopping and starting of the sheet 3 are prevented from occurring, thus printing quality is improvable. |
