Abstract: An apparatus for realizing a method for applying a flowable substance to a flat or curved product includes a nozzle unit including a nozzle valve having a nozzle end with an outlet opening. The nozzle end has at least one cooling zone. A mechanism supplies the at least one cooling zone with at least one of moist and temperature-moderated air so that condensation water forms as a result of the impact between the supplied moist and/or temperature-moderated air and the at least one cooling zone. A discharge device to which the nozzle end is operatively connected is adapted to discharge the condensation water or the condensation water loaded with dirt particles for ensuring a continuous, unobstructed flow of the flowable substance from the nozzle outlet opening.

Abstract: A method and apparatus for applying a flowable substance to a flat or curved product using a nozzle unit. The nozzle unit includes a nozzle valve that has a nozzle end with an outlet opening. Moist air and/or temperature-moderated air is admitted to a zone of the nozzle end to form condensation when the supplied moist and/or temperature-moderated air hits the nozzle end zone. Drying up or agglutinating of the flowable substance is thereby prevented at the outlet opening of the nozzle end to secure a continuous, unobstructed flow of the flowable substance from the outlet opening.

Abstract: A method for operating a device that applies a force to a print sheet during a folding operation, wherein the print sheet is in a specified starting position prior to the folding operation. Braking-force triggering pulses are directed toward the print sheet to counter the acceleration of the print sheet in the starting phase of the folding operation and/or to counter fluttering movements that occur during the intake of the print sheet. The pulses exert an intermittent, uniform or oscillating force onto at least a section of the print sheet. The pulses are controlled by a control unit which operates based on control profiles resulting from queried operating parameters and/or based on stored control profiles.

Abstract: A device for braking and positioning a print sheet in a processing machine, wherein, along a feeding direction for the print sheet, at least one mechanism exerts a braking force onto the print sheet, to position the print sheet in connection with an operation of a downstream-arranged processing station.

At least a second mechanism is operative to generate at last one frictional force that acts upon the print sheet, wherein with aid of at least one of the first mechanism and the second mechanism, intermittent, uniform or oscillating braking forces are generated that act upon the print sheet. A control unit controls the braking forces based on at least one of changeable control profiles resulting from queried operating parameters and stored control profiles.

Abstract: A method and a device for the quality inspection and testing of a flat print product. A print product, including at least one structural element, is initially deposited on a support element and illuminated by at least one light source. At least one image of the illuminated print product is generated using at least one image recording unit. An image is also generated of at least one structural element on the support element and a geometric object of the support element is determined from the at least one structural element of the support element. Actual values for the at least one geometric object of the support element are compared to predetermined desired values for this geometric object and the result of the comparison is used for controlling the further processing of the print product.
