  • the ink is further supplied to the printing surface via the other ink distributing rollers.
  • the amount of ink to be supplied to the printing surface is adjusted by controlling the period of time during which the vibrating roller 3 is in contact with the fountain roller 1.
  • the tank 11 When the preceding printing operation has been completed, the tank 11 is first shifted to the forward cleaning position to press the blade 12 against the surface of the fountain roller 1 as shown in FIG. 4, and the fountain roller 1 is rotated, whereby the ink A remaining in the fountain is collected into the tank 11, and the ink remaining on the surface of the fountain roller 1 is almost completely scraped off by the blade 12.

Since the groove 31 having the leading end of the sheet 33 inserted therein extends to opposite ends of the take-up, member 24, the sheet 33 can be readily slipped off by pulling the sheet in either direction.
  • the take-up member 24 from which the sheet 33 has been removed is installed between the opposed bearing members 28, 30 again, and the subsequent printing operation is carried out using a fresh roll of sheet.

Accordingly, the surface of the fountain roller 1 only needs to be cleaned by hand when so required.
  • the arrangement therefore ensures facilitated cleaning work and a shortened replacement time. Since the fountain-forming face 17 of the fountain member 15 is covered with the sheet 33, no ink will adhere to the face 17. For replacement, the sheet 33 needs only to be so moved as to release the used sheet portion from the fountain-forming face 17 and to bring a fresh sheet portion before use into intimate contact with the face 17 without the necessity of cleaning the fountain member 15.
