Abstract: An apparatus is disclosed for transporting packagings from a packaging apparatus having two dropping channels to a transport container. A first transport element has compartments, the center-to-center distance of which corresponds to a center-to-center distance of the dropping channels, receives the packagings from the packaging producing apparatus. A second transport element has compartments for transporting the packagings to the transport container, wherein the center-to-center distance of the compartments of the second transport element corresponds to half of the center-to-center distance of the dropping channels. The apparatus has a transfer unit for transferring the packaging from the first transport element to the second transport element, and to which a positioning device is assigned for positioning the compartments of the first transport element relative to the compartments of the second transport element.

Abstract: A process for treating an imaged printing form, in particular a printing form covered with amphiphilic molecules or with polymers, such as saccharides, includes applying a gum, in particular a microscopic gum layer, to the surface of the printing form in the liquid state. The gum is removed or reduced down to a remaining nanoscopic covering after a short or negligible time interval, relative to the time interval until the application of lithographic liquid, for example dampening solution or printing ink, to the surface. The removal or reduction of the gum is preferably carried out in the still liquid state, i.e. before the applied gum dries on, and preferably immediately after the application. The remaining gum covering protects the printing form against contaminants and increases its hydrophily/hydrophoby contrast. An apparatus for treating an imaged printing form, a re-imageable printing form and a machine for processing printing material, are also provided.

Abstract: An apparatus and method for treating a rotating printing technology surface, especially a re-imageable printing form, with a process liquid, such as cleaning, covering or rinsing liquid, include jet nozzles disposed along a straight line substantially parallel to the axis of rotation of the printing technology surface, and a cloth device substantially parallel to the axis of rotation. The nozzles pivot about a pivot axis substantially perpendicular to the axis of rotation for producing a substantially uniform distribution of process liquid parallel to the axis of rotation. The cloth device preferably has a cloth with segmented or calendered portions substantially parallel to the axis of rotation, for substantially limiting spread of process liquid in the cloth parallel to the feed direction of the cloth and assisting substantially uniform distribution of process liquid parallel to the axis of rotation. Machines for processing printing material and for treating printing forms are also provided.

Abstract: A method for correcting the lateral position of a printing material, includes gripping the printing material with a transport unit, rotating the transport unit in a lateral position correction angular range for correcting the lateral position of the printing material, and rotating the transport unit out of the lateral position correction angular range while retaining the correction of the lateral position of the printing material. An apparatus for correcting the lateral position of a printing material, a printing material conveying system and a machine for processing printing material, are also provided.

Abstract: A sheet processing machine for the processing of sheets of paper, cardboard, and the like, includes at least one processing station, one delivery unit, one sheet transport system including circulating gripper carts, which are driven by individually actuated linear drives, a machine control system and braking devices located in the entry zone of processing stations. The back edge of the respective sheet at its stop position in the delivery unit and/or the at least one processing station lies directly above the back edge of the delivery stack and/or the back edge of a tool or die of the processing station.

Abstract: A method for treating a reusable printing technology surface, preferably a printing form that can be re-imaged, with at least one liquid, for example cleaning fluid, rinsing liquid, solution of amphiphilic molecules or gumming agent, includes rotating the printing technology surface about a cylinder axis, applying the liquid to the printing technology surface in the form of a jet and at a varying angle and contacting the printing technology surface with a movable cloth. The printing technology surface is rotated at a varying rotational speed. The rotational speed is preferably varied in stages, in particular increased, in order to achieve the best possible treatment results, for example cleaning and (re-) covering with amphiphilic molecules. The method can preferably be implemented in a printing press or a plate exposer. A machine for treating a reusable printing technology surface and a machine for processing printing material, are also provided.

Abstract: A sheet brake for braking sheets made from a printing material contains circulating brake elements and at least one sheet support that is disposed between the brake elements and forms a blowing device. The sheet support contains a first nozzle array having air nozzles and a second nozzle array having air nozzles. The air nozzles of the first nozzle array are configured to produce blown air volumetric flows, which are smaller than blown air volumetric flows from the air nozzles of the second nozzle array.

Abstract: A method of orienting a sheet in a sheet punching and embossing machine and a sheet punching and embossing machine includes at least one processing station, a machine control system and a sheet transport system including circulating gripper carts with gripper bridges on which grippers are secured. The sheet is gripped and moved through the machine by the grippers. The sheet transport system includes circulating chains.

The gripper bridge of a gripper cart is connected by spring elements to the travel carts, and the gripper bridge includes a contact surface which can be brought into contact with at least one driven adjustment element of a respective processing station to orient the sheet in the processing station and to lower the gripper bridge into the processing stations.

Abstract: A device for correcting the lateral position of a printing substrate, preferably a sheet of paper, held by a gripper bar and conveyed in a transporting direction has a linear drive that includes a first primary part and a first secondary part configured as a first carriage and associated with the first primary part, and a second secondary part configured as a second carriage. The first carriage and the second carriage are arranged on the same side of the printing substrate in the lateral direction and—to correct the position of the printing substrate in the lateral direction—are movable relative to each other in the direction of transport. Such a device may be used for transporting printing substrates and for correcting the register position of printing substrates in machines for processing printing substrates, preferably printing presses or machines for the further processing of printed products.

Abstract: In a method for producing an air restrictor, use is made of at least one liquid or tacky substance to join perforated plates to one another and to seal the air restrictor. The substance can be, for example, an adhesive contained in capsules. The adhesive is liberated by bursting the capsules inserted between the perforated plates.
