[0053] The machine 01 used for processing sheet paper 02 is also used for inspecting sheet paper 02. These sheet papers 02 are sheet papers 02 of the corresponding substrate 02. The machine 01 may have other devices for processing sheet paper 02, for example. Examples of these devices include: coating devices, such as primer coating devices and / or printing devices and / or painting devices; or forming devices, such as cutting devices and / or punching devices and / or perforating devices and / or folding devices. Therefore, the machine 01 is preferably designed as an inspection machine 01. For example, the machine 01 may also be designed as a sheet paper processing machine 01, preferably a coating machine 01, and in particular a printing machine 01. If a coating machine 01, and in particular a printing machine 01, is shown above and / or below, the corresponding description also applies to a simple inspection machine 01, provided that there is no contradiction. For example, the machine 01 may be additionally or alternatively designed as a forming machine 01. Preferably, machine 01 is designed as a machine 01 for processing single sheets of securities 02, particularly as a securities processing machine 01 and / or a securities inspection machine 01 and / or a securities printing machine 01. For example, machine 01 is designed as a single-sheet printing machine 01, particularly a single-sheet rotary printing machine 01, or more preferably as a single-sheet securities printing machine 01.

[0054] The machine 01 has at least one inspection device 08; 768 for inspecting the single sheet 02; 768. The at least one inspection device 08; 768 is preferably arranged so as to be able to detect the single sheet 02 passing therethrough. Preferably, the machine 01 is equipped with a conveying path provided for conveying the single sheet 02. The conveying path preferably begins at a substrate feed device 100. The substrate feed device 100 is for example designed as a single sheet feed device 100, in particular as a single sheet pusher 100. Preferably, the machine 01 has at least one single sheet pusher 100. Alternatively, the machine 01 has at least one unwinding device and at least one cross-cutting device.

[0055] The machine 01 has for example at least one single sheet processing unit 200; 500; 600; 700. The at least one single sheet processing unit 200; 500; 600; 700 is for example designed as a single sheet printing unit 200; 500; 600; 700. Depending on the specific embodiment, different printing processes can be implemented.

[0056] The single sheet 02 can for example be formed from paper based on cellulose or preferably based on cotton fibers, plastic polymers or hybrid products thereof. The single sheet 02 can be uncoated or coated before being inspected and / or processed by the machine 01. The single sheet 02 can be unprinted or printed one or more times or otherwise mechanically treated. On the single sheet 02, a plurality of printed sheets, in particular printed sheets of banknotes to be produced, are preferably arranged side by side in a row, and a plurality of such rows of printed sheets or their printed sheets are arranged one after the other in the conveying direction T or are correspondingly arranged in the course of processing the respective single sheet 02.

[0057] The substrate feeding device 100 or the single sheet feeding device 100 of the machine 01 is preferably arranged at the start of a conveying path for conveying the substrate 02, in particular the single sheet 02. The at least one substrate feeding device 100 preferably has, for example, a feeding section 101 designed as a belt table 101. For example, at least one holding device is arranged, which is preferably designed as a pile plate.

For example, the substrate feeding device 100 has at least one non-stop device for uninterrupted supply of the single sheets 02 when a subsequent pile is arranged. The belt table arranged behind the single sheet pile is designed, for example, as a suction belt table. For example, at least one sheet infeed device, which is referred to as a single sheet infeed, is arranged, which preferably comprises an infeed table and at least one movable front stop. The single sheet infeed 100 preferably has at least one vibrating gripper or vibrator. Preferably, along the conveying path provided for conveying the single sheets 02, a receiving drum 102 is arranged behind the vibrating gripper.

The single sheet delivery device 900 preferably comprises at least one single sheet feeding system 904, which is in particular designed as a chain feeding system 904 or a chain gripper system 904. The single sheet feeding system 904 comprises, for example, a traction mechanism which is moved by means of drive and deflection devices, which drive gripping devices for conveying the single sheets. The gripping devices have holding mechanisms for receiving and holding the single sheets 02. Grippers, in particular clamping grippers and / or suction grippers for gripping the edges of the single sheets, can be used as holding mechanisms. By means of the single sheet delivery device 900, the single sheets 02 are preferably deposited in the form of a corresponding sheet stack on at least one conveying carriage or, further preferably, on one of a plurality of conveying carriages, for example designed as trays or other types. For example, single sheet guiding devices and / or drying and / or curing devices 906 are arranged in the single sheet delivery device 900. The single sheets 02, which are preferably decelerated by means of braking devices, rest on a front stop and are thus deposited in a line in the form of a corresponding sheet stack.

Single sheets 02 which are considered to have defective or faulty print can then be collected on one of the stacks, while so-called "good single sheets" are deposited on another stack.

[0060] For example, the sheet delivery device 900 has at least two, further preferably at least three output stations 901; 902; 903, in particular arranged one after the other along the conveying path for conveying the single sheets 02.

Stacks comprising a plurality of individual sheets 02 are preferably transported to the substrate feed device 100 and / or removed from the individual sheet delivery device 900. The conveying path of these stacks is not to be counted as the conveying path for conveying the individual sheets 02. For example, at least one full-sheet monitoring device 773 is arranged along the conveying path for conveying the individual sheets 02. This is used, in particular, to detect the arrival of the individual sheets 02 at the intended time and / or the intended shape of the side edges of the individual sheets 02.

Here, the width of the individual sheet 02 is in particular to be understood as its dimension in the transverse direction A. This is preferably independent of whether the width of the individual sheet 02 is greater than or less than the horizontal dimension of the individual sheet 02 which is orthogonal thereto, which further preferably is the length of the individual sheet 02. The working width of the machine 01 preferably corresponds to the working width of the individual components of the machine 01.
