Abstract: A printing machine contains a transfer unit for transferring a transfer layer onto a print carrier in a transfer nip. The printing machine further has at least one applicator unit for applying an adhesive to the print carrier. The applicator unit precedes the transfer unit, and the transfer layer is detached from the carrier film in the transfer unit in the regions in which adhesive is applied. By printing units being converted into transfer units or applicator units, the functionality of the printing unit for a printing operation is lost. If the applicator device and the transfer device are located in this order on an impression cylinder of a printing unit, the applied adhesive is not predried sufficiently. To overcome these disadvantages, the transfer unit is a further processing unit and has at least one further processing device which follows the transfer nip and which acts on the print carrier.
