In an example of the disclosure, first and second print jobs are received at a printer. The first and second print jobs each include production frames. The first and second print jobs are printed with a media roll change occurring during printing. A first finishing device information nonproduction (“FDIN”) frame and a second FDIN frame are printed. The first and second FDIN frames include coded information regarding the first print job and the second print job, respectively. The coded information is for reading by a scanner at a finishing device. A press calibration nonproduction (“PCN”) frame that includes a printer calibration diagnostic is printed. A scanner at the printer is caused to capture the printer calibration diagnostic. A calibration operation is performed at the printer utilizing data or attributes captured from the printer calibration diagnostic.

A device for further processing web- or sheet-type stock comprises a further-processing section, in which stock that is supplied on the input side can be processed into printed products. The further-processing section comprises, in the guide path of a processing line through which the stock has run, at least one first combining device relative to the stock path, which can combine one- or multi-layer stock sections to a bundle; a second combining device which can combine the bundles formed by the first combining device to a bundle stack downstream of the first combining device; and a transverse folding device which is arranged functionally downstream of the second combining device and which transversely forms the bundles or bundle stacks relative to the conveying device on the input side when they exit the second combining device. A device for joining several layers is placed in the guide path, such that it can join several or all of the stock sections combined in the first combining device into a bundle, before they are received by the second combining device and is associated with, are arranged downstream of the first combining device. During production of the products, a combined bundle is stapled before it is combined with one or more other bundles and is then transversely folded. In addition, a longitudinal cutting device is provided in the guide path downstream of the transverse folding device.

A method for separating printed products, that are printed together onto a sheet of printed products, is disclosed. The printed products are printed onto a sheet in a printing press and are separated in a cutting system by a cutting device. Each of these printed products has an identification feature that identifies its respective position on the sheet. The sheet becomes deformed as it passes through the printing press. The separated printed products, which are likewise deformed, as a result of the deformation of the sheet, are inspected, in a quality control device which is located downstream of the cutting system, for compliance with the tolerance, at least with regard to the respective length or width of the printed products. For each printed product that has been identified, in terms of its position, the quality control device detects information relating to an exceeding of the tolerance, at least for the length or width of the printed product, and transmits that information, assigning that information to the position identified on the sheet, to a control unit of the cutting system. Based on the information transmitted by the quality control device, for printed products that are arranged in the same position on the sheet, and which will subsequently be separated in the cutting system, the control unit of the cutting system adjusts the relevant sheet and the cutting device in their respective positions, relative to one another, in such a way that each of the printed products to be separated complies with the respective tolerance. Compliance with the tolerance is achieved in that the position of the sheet and of the cutting device to be adjusted relative to one another is calculated in the control unit using a mathematical optimization method. The sheet is placed on a cutting table in the cutting system. The control unit of the cutting system adjusts the position of the sheet relative to the cutting device, according to the calculated position.

A folding machine for folding fiber products and fiber products formed and stacked thereby are disclosed. The folding machine includes two folding devices, each of which includes a cutting device, a delivery wheel, a folding-line wheel, a platen wheel, and a folding wheel. The cutting device cuts the fiber product and transports the cut fiber product to the delivery wheel. The folding-line wheel is adjacent to the delivery wheel for making a first folding line on the fiber product carried by the delivery wheel, and then the platen wheel folds the fiber product along the first folding line. Subsequently, the once-folded fiber product is transported to the folding wheel. The folding wheels of the two folding devices are adjacent to each other and are used to fold the fiber product passing therethrough for a second time, and thus fiber products with three folds are formed.

The present invention methods for manufacturing absorbent articles that involve the placement of absorbent cores having variable absorbency levels on consecutively aligned absorbent articles within the same manufacturing line. Additionally, the present invention also includes the provision of single packages of disposable absorbent articles that contain a first absorbent article having a first absorbency level and a second absorbent article having a second absorbency level, wherein the second absorbency level is higher than the first absorbency level.
