Definitions

  • a printing machine is known in which such a sheet turning device is arranged between the printing units.
  • the printing cylinder and the transfer drums of this printing machine are at an angle to each other, which causes a same constellation of the printing units to each other.
  • the bow turning device is designed so that this constellation is maintained during recto printing. This ensures that the channels of the plate cylinder are always in the same position, so that the plate change can be carried out simultaneously in the mode of recto printing.
  • the new printing plates are fed.
  • the position of the cylinder is not changed here.
  • the printing plates are fed simultaneously and fixed with the known means on the cylinder circumference of the plate cylinder 11, 21.
