Abstract: The aim of the invention is to improve the supply of transfer foil in a coating module in which the image-forming layers of a transfer foil are transferred to a printing material. To achieve this, a partial pressing surface is located in the coating module for transferring the layers of the transfer foil. This permits targeted control of the foil feed. The transfer foil can be fed past a pressure cylinder in an approximately tangential manner and with a limited width.

Abstract: In a method for determining the degree of hardening or drying of one or more printed ink and/or coating film(s) on a substrate, for instance, paper, cardboard, plastic film or composite materials, a faster and more efficient measuring method can be found that furthermore supplies secure and easily interpreted results. The method is to be used in the mass production printing processes comprising intaglio printing, flexographic printing, screen printing or offset printing. The degree of hardening or drying is determined indirectly by way of the change in the mechanical and/or viscoelastic properties of the ink and/or coating films on the substrate that result from the hardening or drying process. The detection of acoustic waves by means of a piezoelectric sensor is used as the measuring method.

The processing machine has at least one printing or coating group and a cylinder that is coupled to a direct drive and is decoupled mechanically from a main drive acting on a gear train of a plurality of sheet transport cylinders and that can be driven in a given way at least relative to the sheet-guiding cylinders. The cylinder having an associated inking group with an inking group roller that can be driven by the main drive and gear train. Printing contact in a contact zone of the cylinder carrying the printing form with an adjacent rubber blanket cylinder is cancelled for cleaning. The inking group roller of the inking group is separated on a drive side from the sheet transport cylinders driven by the main drive and gear train. The inking group roller is coupled on the drive side to the cylinder carrying the printing form.

Abstract: Exposed printing plates are bent in the area of a bending device to form a leading end and a trailing end. Each exposed and bent printing plate is grasped in the area of the bending device at the leading end or at the trailing end of the printing plate by means of a gripping bar and transferred together with the gripping bar to a transporting device. The transporting device transports the printing plate together with the gripping bar toward a printing press, where the printing plate is removed together with the gripping bar from the transporting device in the area of the printing press. While grasped by the gripping bar, the plate is transferred to a form cylinder of a printing mechanism of the printing press.
