Abstract: In order to make holes with different spacings between them, a punching tool is provided with punching dies on its circumference and interacts with an impression cylinder. Between two punching operations, either of the punching dies and the impression cylinder is driven, at times, at a circumferential speed that is greater or smaller than the movement speed of the material web that is to be punched or is stopped briefly and, until the next punching operation, brought once again to a circumferential speed that corresponds to the movement speed of the material web that is to be punched.

Abstract: Sheets of different formats, i.e. of different format lengths, are transported in a feeding direction one behind the other; and at a certain conveying speed, to at least two collecting drums, which have essentially cylindrical lateral surfaces. Each of these collecting drums is driven about an axis of rotation at a circumferential speed, which corresponds essentially to the feeding speed of the sheets. The first incoming sheet is secured temporarily on one of the collecting drums, while the following, second sheet is secured temporarily on the other collecting drum. At a suitable point in time, the two sheets secured on the collecting drums are detached from the collecting drums and brought together with the third fed sheet to form a sub-product or end product.

Abstract: In order to punch a moving material web there are two punching units present, which are arranged one after another in the direction of movement of the material web. Each punching unit has two punching tools, which interact with a rotatably mounted back-pressure cylinder that can be driven. The punching tools are arranged on a rotatably mounted drive shaft that can be driven, and their position can be adjusted in the direction of the longitudinal axis of the latter and locked in various working positions. Each punching tool has a cylindrical base, to the periphery of which a punching strip which is provided with at least one punching shape is fixed such that it can be replaced. The drive shafts can be driven independently of the associated back-pressure cylinder.

Abstract: In order to form two longitudinal folds in a material web, there are two plow folding units which extend in the vertical direction and are arranged behind one another in the movement direction of the material web. Each of the plow folding units has two guide elements for the material web, which guide elements are arranged in the manner of a gable or saddle roof. The guide elements are arranged behind one another in the movement direction of the material web and enclose a folding angle between them. The folding angle between the guide elements of the second plow folding unit which is arranged downstream of the first plow folding unit has a magnitude of at least 100°, preferably of at least 140°.

Abstract: In a cylindrical knife holder rotatable about its longitudinal axis, at least one groove, which is open towards the peripheral surface thereof, is present. The groove extends in the direction of the longitudinal axis of the knife holder. Inserted exchangeably in this groove is a perforating knife, the perforating edge of which protrudes over the peripheral surface of the knife holder. The perforating knife, which can be clamped in the groove by means of a releasable clamping device, is supported, at its end lying opposite the perforating edge, on a stop element disposed in the groove. The stop element rests on supporting elements distributed over the length of the groove, which are adjustable in directions running transversely to the longitudinal extent of the groove. The supporting elements define the once set radial position of the perforating knife.

Abstract: In order to form stacks, of which each forms a book block, folded sheets are provided with an adhesive application or layer of adhesive before they are placed on one another. Said adhesive application is applied to the sheets adjacent to the folded edge of said sheets and extends in the direction of said folded edge which comes to lie in the spine of the book block. The adhesive can be applied as a continuous track or as a track which is interrupted multiple times, or else in a punctiform manner. The sheets are joined to one another in the stack by means of said adhesive application, with the result that they maintain their position within the stack during further transport of the stack.

Abstract: In a material web which is printed in a digital printing station and moved in an advancement direction, a first material-web strand, which is formed by at least one printed material-web portion, is combined with a second material-web strand, which is formed by two printed material-web portions, by folding. The two material-web strands are connected to one another by an adhesive. Subproducts are then severed from the thus interconnected material-web strands by cross-cutting. These subproducts comprise a first printed sheet, severed from the first material-web strand, and a second printed sheet, connected to the first printed sheet and severed from the second material-web strand. The subproducts are then positioned one upon the other to form a stack, the subproducts being connected to one another by an adhesive in the region of the subsequent folding line. The stacked subproducts are then folded about a folding line to form an end product.

Abstract: The invention concerns a gathering device (10) with a revolving body (14) for the formation of sheet stacks (34, 35) from individually delivered sheets (30, 31). Thanks to a device (23) for generating a holding force, preferably by electrostatic charging, which is arranged essentially outside the outer surface (16) of the revolving body (14), the sheets (30, 31) can be secured to the revolving body (14) without the revolving body (14) needing to have receiving positions dictated by mechanical means. Therefore, the receiving positions can be adapted as desired to the particular requirements.

Abstract: A device for forming stacks of sheet products, in particular of paper products, may include the paper products being supplied in an input stream by a feed conveyor to a transfer section. The device may also include at least two set-down tables each including a set-down surface for receiving stacks of the supplied paper products. The set-down tables may move along a circuit-like table-circulating path and may be flexible at least in some segments to conform to shapes of curvatures located in at least some parts and subregions of the table-circulating path. As a result, it is possible for the set-down tables to be guided into the curvatures with a leading front side edge of each of the set-down tables being a leading edge in a circulating direction of the set-down tables. The stacks of stacked paper products may then be transported away from a delivery section by a removal conveyor.

Abstract: A method of producing a newspaper having at least one section which is formed from at least one centrally folded printed sheet.

Abstract: A paper web (8) drawn off from a supply roll is periodically moved past a rotary cutting device (12), by an advancement arrangement (11), at an advancement speed (v1), which is equal to the sheet draw-in speed (v3) of the sheet draw-in arrangement (3) of a high-speed printer (2). Said rotary cutting device severs in each case one individual sheet (31) from the moving paper web (8). This individual sheet is received by a conveying device (13), which leads the individual sheet (31) to the sheet draw-in arrangement (3) at a constant speed, i.e. at a conveying speed (v2), which is likewise equal to the draw-in speed (v3) of the sheet draw-in arrangement (3). Each individual sheet (31) cut off from the paper web (8) thus already moves at the draw-in speed (v3) of the sheet draw-in arrangement (3) at the point in time at which it is cut off, and it maintains this speed until it runs into the printing unit of the high-speed printer (2).

Abstract: A method of producing a newspaper (7, 8, 9) comprises at least one section (3, 4, 5) which is formed from at least one centrally folded printed sheet (1), and an apparatus implements the method.

Abstract: The invention relates to a process and an apparatus for folding sheets (2), in particular printed sheets. A sheet (2) which is fed in a state in which it lies horizontally in a feed plane (7) is fed to at least two incipient-folding rollers (4) by a rectilinear knife (6), which can be moved perpendicularly to the feed plane (7), and is received between the incipient-folding rollers (4) in order to form a fold (8). The sheet is then conveyed away in the direction of the fold without being completely closed. The sheets are conveyed away by at least two removal rollers (5), by means of which the fold is also completed. The sheets are advantageously folded and conveyed away in one process step in the case of the invention, an additional opening step prior to the further processing of the sheet being dispensed with.
