Abstract: The present invention concerns a method for producing an image in the edge of a volume of paper sheets. The invention can be used for numerous stationary products, note pads, exercise books, and the like. In the present invention, the images are printed not on the edges but on the paper surface. The method comprises a series of steps: printing-realigning-guillotining. The invention also concerns the insertion of a segmented image, systematically in edges and added in the make-up of a volume, for use in a complex technological process.

Abstract: Machine for the production of flexible material sheets comprising at least one folding unit housing at least one cutting cylinder, to which a suction cylinder is opposed, and a gripping cylinder for transversal folding and/or conveying flat products by suction. A second suction cylinder for a second transversal fold and/or for conveying flat products and a second conveyor cylinder for conveying folded products or flat unfolded products may be associated downstream to said machine.

Abstract: A newspaper producing method can produce a plurality kinds of newspapers different in page numbers and colors by using a single printing unit. This method includes a plurality of printing cycles, each of which produces a plurality of lateral printed rows on each side of a continuous web, with each row having different contents relative to each other, with each row having at least two printed segments in a width direction of the continuous web, and with rows on opposite sides of the continuous web corresponding to each other. This printed continuous web is cut with respect to each of the lateral printed rows and each two-page spread of newspaper, and these cut portions are set and are delivered for every printing cycle. Each set of these portions is folded at a longitudinal central portion of a two-page spread thereof.

Abstract: A device for adjusting conveyors for printing presses that process flat products or further processing units (40) arranged downstream therefrom, in which are received belt movers (1) containing a plurality of individual belts (5) for transporting the flat products, the belt movers including guide rollers (6) and setting rollers (7), which have a drive (2), and use tensioning devices (3) which keep constant the tension in the individual belts (5) of the belt mover (1). Accommodated in the further processing unit (40), whether it be a folder with pins or a folder that works without pins, arranged downstream from the rotary press, are shafts (16, 28, 34) having elements (25, 31, 39), which are arranged in a stationary mount and guide the individual belts (5). Supported on these so as to enable sliding in the axial direction, symmetrically with respect to the machine center (13), are movable elements (20, 27, 36), which guide, drive, and/or prestress the individual belts (5).

Abstract: A folder includes a cutter for cutting a web of material into signatures, a folding device for producing at least one fold in a signature cut from the web of material, at least one delivery device and one conveyor path for directly feeding the cut signatures to the delivery device while avoiding the folding device. The signatures can be guided either by the conveyor path or through the folding device. A signature switch of the conveyor path distributes the signatures to two flies or paddle wheels that deliver to conveyor belt devices that are arranged in parallel to the rotational axes of the paddle wheels.

Abstract: A high speed web cutting and tuck folding machine feeds webs downstream between overlying and underlying runs of feed belts having cutting and tuck folding openings spaced along the belts. Lead segments of the webs are cut at a cutting station and are fed downstream to a tuck fold station where they are drawn through tuck fold openings, folded and stacked. The machine is readily adjusted to vary the length of the cut segments and the relative lengths of the legs of the segments when folded.

Abstract: A sheeting apparatus and method are disclosed for cutting a web of material passing through a printing press into sheets. The apparatus comprises a rotating die roller including a knife mounted longitudinally thereon, the die roller being connected to the printing press transversely to the web and moveable between an engaging position wherein the knife rotates into cutting engagement with the web and a released position wherein the knife does not contact the web. A pair of springs bias the die roller into one of the engaging and released positions and a pair of linear actuators are provided to selectively move the die roller into the other of the engaging and released positions in opposition to the spring bias. The sheeting apparatus further includes a programmable controller for automatically operating the actuators. The method involves cyclically moving the die roller between the released position and the engaging position at intervals to cut the web into sheets of a predetermined length.

Abstract: A device for guiding material webs (A through D; E through H) via an angle-bar deck (2), including a folding section that is arranged on a plurality of planes (3.1, 3.2, 3.3), from where the material webs (A through D), (E through H) enter folding apparatuses (4), (5). Accommodated on longitudinal folding devices (8), (9) are infeed elements (7), which have guide sections (13), (14) that are-able to be operated independently of one another.

Abstract: In a rotary printing machine, a folder operatable in different folding modes, and having a copy-guiding cylinder to which copies severed from a material web by a cutting-cylinder pair are feedable, the copy-guiding cylinder having a circumferential surface wherein gripping and cross-folding elements are accommodated, includes a device having movable circumferential-surface parts guidable by a respective guide element and, during folding-mode changeovers, selectively extendable into the circumferential surface of the cylinder and retractable between stationary and movable segments of the copy-guiding cylinder which are positionable relative to one another.

Abstract: Several printing units are arranged in a row for printing on as many separate webs traveling in centerline alignment and in phase with one another. At least one preselected web, on issuing from one printing unit, is directed over an angled guide rod thereby to be turned 90 degrees out of phase with the other, unselected webs. Subsequently traveling over a triangular shaped former, the preselected web is folded along a centerline thereof, back into phase with the unselected webs. The preselected web, already formed, and the unselected ones, yet unfolded, are then all superposed one upon another, with the fold of the preselected web in register with the aligned centerline of the unselected webs. The superposed webs are then folded by another former along the aligned centerline of the unselected webs. Subsequently fed into a cutting and folding device, the webs are cut and folded transversely into individual multiple-page signatures each having one center spread in addition to the usual inmost center spread.
