  • Patent number: 8584584
    Abstract: A noncontact web stabilizer is provided in which members located on opposite sides of a web reduce out-of-plane web vibrations. Specifically, a first member is located on one side of a web and a second member is located on the opposite side of the web. Both members are positioned so that the distance between the web and the members decrease in the direction that the web is moving, creating opposing regions of high pressure that force the web toward its nominal running position, thereby reducing out-of-plane web instability.

  • Patent number: 6422552
    Abstract: A movable folder assembly includes one or more folders slidingly supported on a pair of rails and an actuator for moving the folder on said pair of rails. The actuator may include a hydraulic cylinder and a control unit for controlling said hydraulic cylinder. The folder(s) is supported on said rails by bearings. Preferably, the bearings are linear bearings, and most preferably, the folder(s) is supported on at least one of said rails by dual-type linear bearings. The folder(s) may be used in conduction with a former board arrangement in a web-fed rotary newspaper printing press which includes a first and a second row of former boards each row including a first, second and third former board for longitudinally folding one or more ribbons passing over the former boards. The first row of former boards is arranged above the second former board, and a movable folder is located below one of the former boards of the second row of former boards for crossfolding and cutting the ribbons into signatures.

  • Publication number: 20020083854
    Abstract: A tension control device for a printing press having an adjustment roller, with a web of the press passing from a supply roll of the web to the adjustment roller. Means are provided for measuring the tension on opposed sides of the web passing downstream from the adjustment roller, and means are provided responsive to the measuring means for automatically approximately equalizing the tension of the web by adjustment of the adjustment roller on one end only of the adjustment roller.

  • Patent number: 6405098
    Abstract: A control arrangement for controlling web unwinding equipment used for feeding webs to a web-fed rotary printing machine stabilizes a swing roll used to tension the web at a central position via an integrator in a manner independent of the coefficient of friction. A proportional and differential element is connected in parallel with the integrator. The inputs of the integrator and the proportional and differential element are connected directly or indirectly to a swing-roll transmitter whose output is dependent on a position of the swing roll. The outputs of the integrator and the proportional and differential element act on an adder element. The output of the adder element acts directly or indirectly on a brake for braking the rotation of the wound roll.

  • Patent number: 6371020
    Abstract: A web guiding system for a web-fed rotary printing press includes a web guide roller which contacts the printed surface of a print-carrying web. The effective diameter of the transfer cylinder which prints the print-carrying web is the same as, or is an integral multiple of the diameter of the web guide roller.

  • Patent number: 6327975
    Abstract: A web-fed offset printing press has printing units each comprising a plate cylinder, a blanket cylinder, and an impression cylinder, the impression cylinder being movable into and out of rolling engagement with the blanket cylinder via the web. A first printing unit prints a first image portion on the web at prescribed spacings, by moving the impression cylinder away from the blanket cylinder each time one first image portion is printed. A second printing unit prints a second image portion on the spacings left on the web by the first printing unit, also by moving the impression cylinder away from the blanket cylinder each time one second image portion is printed. A variable speed motor rotates each blanket cylinder, while each time the associated impression cylinder is held away to create a space on the web for causing printing of the first or the second printing portion at required spacings.

  • Patent number: 6230616
    Abstract: A storage device for receiving a loop section of a flexible material web (8) moved in a conveying direction (18) between a feed area upstream of the storage device and a discharge area downstream thereof is described, the material web speeds at least periodically differing from one another in the feed area and the discharge area. The speed differences are compensated by a length change of the loop section stored in the storage device. On the feed side the storage device has a first pulling device formed by a suction belt (35, 55) and on the discharge side a separate, second pulling device formed by a parallel suction belt (35, 56). As a result of the parallel suction belts the drawn-in loop section is securely held by vacuum over most of its length, whereas between the pulling devices a tensile force-free loop partial section (4a) is moved to and fro in the store longitudinal direction with substantially no shape change in accordance with the store filling.

  • Patent number: 6220157
    Abstract: A printing press includes a pair of in-line central impression cylinders which rotate about parallel axes. A web which is printed on the central impression cylinders is advanced from one of the cylinders to the other along a path which is perpendicular to the axes. The web is advanced from an unwind to the first central impression cylinder along a path which is parallel to the axes, and the web is advanced from the second central impression cylinder to a rewind along a path which is parallel to the axis. The web path between the central impression cylinders is relatively short, and the printed side of the web does not contact any rolls except possibly a laydown roll before the second impression cylinder. The central impression cylinders and the plate rolls are driven by different servo motors, and a controller controls the servo motors for adjusting the repeat of the printed images.

  • Patent number: 6189449
    Abstract: A web width adjusting device comprises a pressure force applying unit for applying pressure force to one side surface of a paper web which is successively traveled through two or more printing sections. Further the web width adjusting device may also include a counter pressure applying unit to apply counter pressure to the other side surface of the paper web. The pressure applying unit (and the counter pressure applying unit) deformes the paper web in a wavy surface which causes the width of the paper web to be shortened. The adjusting factors for the web width are controlled by automatic control system which detects traveling condition of the paper web, the generation of shears in printing, etc.

  • Patent number: 6053107
    Abstract: A preprinted web having a plurality of first repeating images is reprinted with a plurality of second repeating images which are in register with the first images. A register mark is printed on the web for each of the first images. When the web is reprinted, the positions of the register marks are sensed and compared with the positions of the second images, and the unwind tension of the web is adjusted to maintain the relative positions substantially constant.
