The invention relates to a circular knife device (10) for cutting to size sheet-like materials, in particular paperboard and/or textile materials, in particular cover boards and/or covering materials, wherein the circular knife device (10) defines a cutting plane in which the sheet-like materials are arranged and are moved in a transport direction (14), having at least one circular knife (46) and an associated circular knife axis, wherein the circular knife (46) is rotatable about the circular knife axis, wherein the at least one circular knife (46) is movable parallel to the cutting plane and perpendicularly to the transport direction (14) with the result that a blank width of the sheet-like materials is settable in a variable manner, wherein the at least one circular knife (46) is mounted so as to be pivotable about a pivot axis (52) arranged substantially perpendicular to the cutting plane such that cuts at an angle to the transport direction (14) and curved cuts of the sheet-like materials are able to be executed.

A device for shaping a folding region of a lying outstretched book cover includes first and second shaping tools for book blocks having straight and round spines, respectively. A countertool has two counter shaping rails. In a working position, one of the shaping tools is aligned with an inner face of the spine region of the book cover and is configured to raise the spine region of the book cover between the two counter shaping rails to form a spine strip. A single actuator for the shaping tools is in each case arranged in the working position. A tool beam is in each case arranged in the working position and configured to be coupled to the single actuator. Each shaping tool has two shaping rails which are spaced apart, laterally adjustable and are designed so as to be adjustable collectively to change a distance therebetween.

A preheating station for different shaping tools for shaping a folding region of a lying outstretched book cover includes a plurality of receiving spaces for the different shaping tools for shaping different book covers lying outstretched. At least one heating element is arranged in a region of each of the receiving spaces and a temperature sensor is connected to the heating element. A control device is connected to the one heating element and the temperature sensor. A sensor is connected to the control device and configured to detect at least one identifying feature of the different shaping tools received in the preheating station.

A shaping tool for a device for rounding a spine region and for shaping a folding region of a lying outstretched book cover, the folding region being adjacent on either side of the spine region, in accordance with a shape of a spine of a book block, which subsequently forms a book together with the book cover, includes a fixed, convex central shaping strip. Two convex outer shaping rails laterally adjoin the central shaping strip and are laterally adjustable according to a required rounding and width of the spine region of the book cover.

A creasing device is provided that includes a counter-rotating male drum and female drum. The male drum carries a conventional creasing ring with a central rib flanked by shoulders. The female drum comprises a central channel aligned with the creasing rib on the male drum; and a pair of projecting lateral ribs on each side of the central channel that are aligned with the shoulders on the male drum. The lateral ribs press a sheet of the card or paper stock against the shoulders of the creasing ring to better define the edges of the crease and to reduce the tendency of a printed coating on the stock to crack during subsequent folding. The pair of lateral ribs may be provided by a pair of inserts. Alternatively, both ribs and the central channel may be provided by a single insert.

A method for providing a stack of book covers for production of finished books includes supplying a task stack of book covers having identical cover formats and stacked one above another in an unknown or known sequence. Each book cover in the task stack includes an identifier comprising cover information. The book covers are separated out and conveyed from the task stack as separate book covers in a sequence that does not change until a completion signal is transmitted. The separated out book covers are counted, an identifier on each separated out book cover is detected, and cover information is read out of the respective identifier stored. The separated out book covers are deposited on top of one another in the sequence in which they were separated out for forming a detected stack. An identifier is stored that identifies the detected stack together with the temporarily stored cover information.

A sheet processing apparatus that can suppress a reduction in a quality of a finish of a fold part of a stack of center-folded sheets without losing an ease of center-folding. The sheet processing apparatus comprises a creasing unit for forming a folding stripe on a sheet so as to facilitate folding the sheet, and an acquisition unit for acquiring information related to a thickness of the sheet. One or more sheets to be provided with folding stripes are determined, from among a plurality of sheets to be folded, according to the information related to the thickness of the sheets, and each of the determined one or more sheets are provided with a folding stripe.

The invention relates to a case maker comprising a cardboard feed, a blank feed, a glue applicator, the joining device, a turn-in device, a delivery unit and a control unit, with a spreading device of the cardboard feed being arranged downstream of a first cardboard cutting mechanism in the product flow in order to position the cardboard blanks produced from a common cardboard sheet by means of the first cardboard cutting mechanism spaced apart from one another.
