Abstract: Method for depositing different products produced by a printing press in a continuous printing operation, the printing press having at least one controllingly variable printing form, includes separating the products from one another in accordance with a control varying the printing form, and feeding the products individually to a further processing location, and a device for performing the method.

Abstract: Gripper bar for a delivery of a printing press, the gripper bar being carried at respective ends thereof by transport chains and having a multiplicity of grippers with gripper fingers for transporting sheets includes a hollow profiled member having a boxlike profile wherein a gripper shaft is receivable, the boxlike profiled member being formed with lateral openings through which the gripper fingers of the grippers extend.

Abstract: Method of introducing an auxiliary sheet pile carrier above a main sheet pile to be removed, the introduction being effected during uninterrupted feeding of additional sheets above the main sheet pile in a sheet travel direction and in synchronism with the travel of a sheet to be deposited, includes controlling respective drives at a sheet delivery by a control device which determines actual data of a printing press, so that the auxiliary pile carrier traverses a velocity profile identical with a velocity profile of the sheet to be deposited in order to avoid relative movement between the auxiliary pile carrier and the sheet to be deposited.

Abstract: Device for contactless guidance of sheetlike material being dragged along a travel path, the device having a guide surface member extending spaced from the travel path and being provided with air-blowing nozzles, includes a guide zone formed in the guide surface member wherein the air-blowing nozzles are disposed in a manner that a common flow pattern or gap flow formed during guidance of the sheetlike material is determined essentially by a first velocity component in a direction of motion of the material along the travel path and by a second and a third velocity component directed towards two side edges, respectively, of the travel path, the second velocity component being associated with one of the side edges and the third velocity component being associated with the other of the side edge.

Abstract: Individual sheets are singled out in a delivery of a sheet-fed rotary printing press. The delivery has a chain delivery with gripper bars extending transversely to the sheet-transport direction. The gripper bars are disposed on revolvingly driven transport chains and carry spaced apart sheet grippers disposed side by side. The sheet grippers grip the leading edges of the sheets and slave them to a main sheet pile. The gripper release is subject to an adjustable control for delayed sheet release, so that selected sheets may be transported beyond the main sheet pile. Revolvingly drivable suction tapes suction-grip the sheets which are released by the grippers with the delay, and they transport those sheets in the transport direction across and beyond the main sheet pile and onto a single sheet depository. The sheet depository is movably disposed in or on the printing-press frame. The suction tapes have upper suction surfaces at a raised position which extend between the sheet grippers.

Abstract: A folding apparatus of a rotary printing machine includes a combination of a plurality of folded-product guiding cylinders including at least one cylinder with adjustable folding blades and impaling pins, and at least one cylinder with folding jaws, and transfer cylinders with gripper devices as well as perforating devices, the folding blades, the impaling pins, the folding jaws, the gripper devices and the perforating devices being adjustably mounted in the respective cylinders adjacent respective outer cylindrical surfaces thereof, a device operatively connected to at least one of the cylinders for automatically adjusting a fold, the adjusting device being actuatable for varying respective operating positions of the folding blades, the impaling pins, the folding jaws, the gripper elements and the perforating elements relative to one another at the respective outer cylindrical surfaces of the respective cylinders, and a remotely controllable drive for operating the adjusting device.

Abstract: Product delivery system for a printing-press folder having a cutting unit for dividing printed webs of material into a multiplicity of printed copies or signatures, and a gripper cylinder includes a device for alternatively feeding cross-folded copies from the gripper cylinder to a device for producing a second longitudinal fold and to delivery units disposed down-line therefrom, on the one hand, and to a further chargeable delivery unit for cross-folded copies, on the other hand, the copy delivery units being chargeable facultatively in accordance with a respective production mode, the alternative feeding device including a first conveyor surface formed of delivery belts encompassing a 90.degree.-turn, a second conveyor surface disposed within the folder and formed of a conveyor belt, and a swivelable diverter for selectively delivering copies alternatively onto the first conveyor surface and onto the second conveyor surface, the swivelable diverter being connectible with a stacker.

Abstract: A device for the controlled removal of pieces of waste material is provided. The device has a non-rotatable cylinder shaft having an outer surface; a cylinder jacket having an inner surface and an outer surface and having at least one through-hole extending between the inner surface and the outer surface of the cylinder jacket, the cylinder jacket rotatable around the cylinder shaft; and sealing strips between the outer surface of the cylinder shaft and the inner surface of the cylinder jacket. The outer surface of the cylinder shaft, the inner surface of the cylinder jacket and the sealing means define a pressure chamber and a vacuum chamber, so that upon rotation of the cylinder jacket around the cylinder sleeve the at through-holes alternately connect with the pressure chamber and the vacuum chamber. The waste pieces are created when a pair of knives disposed on the outer surface of the cylinder jacket cut a moving web.

Abstract: A folder having, disposed in succession in a web-and-copy traveling direction, at least a first longitudinal folding device, driven severing members, and cross-folding devices formed of folding cylinders to which a first copy delivery is assigned, and a second longitudinal folding device to which folding copies are supplied via a section of a conveyor belt which is disposed over a second loadable copy delivery, includes drawing devices disposed upstream of the severing members in the web-and-copy traveling direction, a first drive for separately and controllably driving the drawing devices, a second drive for driving the severing members and the cross-folding devices, and outwardly swingable conveyor belts having a third copy delivery assigned thereto.
