Claims17
A sheet fed offset printing machine for printing and processing sheets comprising:
- a plurality of sheet fed offset printing units each including an arrangement of a plate cylinder adapted for carrying a printing plate, a blanket or press cylinder in adjacent contacting relation to the plate cylinder, and an impression cylinder free of contact with the plate cylinder in adjacent contacting relation to the blanket or press cylinder for defining a sheet passage nip therebetween,
- one of said printing units being a coating printing unit having a supply of adhesive material and the plate cylinder and blanket cylinder of said coating printing unit being operable for applying an image forming adhesive coating onto sheets passing through the sheet passage nip of the one printing unit, and
- one of said printing units having an integrated transfer foil apparatus comprising a structural unit that includes a transfer foil supply apparatus, a consumed transfer foil removal apparatus, and guide elements for guiding the transfer foil to and away from sheets passing through a sheet passage nip defined in part by the impression cylinder of the printing unit with which the transfer foil apparatus is integrated whereby a film image is applied on the sheets by the transfer of at least parts of an image forming layer of the transfer film onto the sheets.
