Abstract: A drying device contains an upper drying head and a lower drying head. The upper drying head is arranged above a transport plane, in which objects to be dried can be transported in a transport direction through the drying device. The lower drying head is arranged below the transport plane. The upper drying head and the lower drying head contain in each case at least one air outlet slot and the longitudinal directions of the air outlet slots essentially extending parallel to the transport plane and transversely to the transport direction, and in which slot planes, in which the air outlet slots extend, intersect the transport plane at angles which are greater than 0° and less than 90°.

Abstract: In a method for treating objects, the objects are transported through a basin by a transporting device. Treatment solution is introduced into the basin by way of at least one feeding device, which is provided with upwardly directed outlet openings. The treatment solution is sprayed upwards by the upwardly directed outlet openings to form jets of treatment solution. The objects are transported through the basin over the upwardly directed outlet openings and a downwardly facing surface of the objects is brought into contact with the jets of treatment solution during the transport of the objects through the basin. There is also described a treatment apparatus for carrying out such a method.

Abstract: A method for detaching a liquid lamella from a substrate edge is provided. A tear-off front is configured at at least one point of the liquid lamella. A width of the liquid lamella is then reduced by guiding the tear-off front along the substrate edge. Thus, the width of the liquid lamella prior to being torn off the substrate edge can be reduced by at least 50%, as compared to an original width of the liquid lamella.

Abstract: A device treats substrates with a liquid, which device has a conveying device by which the substrates can be conveyed in a conveying direction through a container containing a liquid. A weir has an edge over which the substrates can run and which, at least in sections, extends obliquely relative to the conveying direction of the substrates. The weir is used in the device for treating substrates with a liquid. The weir has at least one edge which extends obliquely at least in sections.

Abstract: A continuous separation installation for the galvanic deposition of a substance on objects includes contacting devices having at least one electrically conductive contact arm. The contacting devices are arranged in areas of the continuous separation installation which are free from an electrolyte used for the galvanic deposition of the substance. There is also described an assembly for a continuous separation installation.

Abstract: A method for operating a cleaning apparatus, having a trough and a brush disposed in the trough, in a printing press, includes first, second and third steps. In the first step, a cylinder of the printing press is cleaned by the cleaning apparatus, with the brush bearing against the cylinder. In the second step, the brush is moved away from the cylinder, and a level of a liquid in the trough is changed, resulting in the liquid being brought into contact with the brush. In the third step, the brush is cleaned by the liquid in the trough. A printing press for carrying out the method is also provided.

Abstract: An apparatus for driving a roller of a printing press includes a main motor configured to drive the roller through a first gear wheel and a first freewheel, and an auxiliary motor configured to drive the roller through a second gear wheel and a second freewheel. A brake that is different from the main motor, for example a band brake, is configured to brake the roller during overrunning of the roller following a machine stop signal. A printing press having the apparatus is also provided.

Abstract: A method for operating a printing press having a printing unit and a cleaning apparatus includes, in a first step, starting up the printing unit in order to print therewith, and in a subsequent, second step, displacing the cleaning apparatus into the printing unit running in printing operation and/or out of the printing unit running in printing operation. A printing press for implementing the method is also provided.
