  • Patent number: 6640716
    Abstract: A method and apparatus for imaging material. A section of a medium is photographed with a first camera having a first field of view. The medium is advanced along a feed direction and the section is photographed with a second camera having a second field of view. At least one of the first field of view and the second field of view is shifted from a nominal location by one or more reflective surfaces. An actual advance of the medium is compared with an intended advance of the medium and it is determined whether at least one of a media advance error and a dimensional change in the media exists in response to the comparing step.

  • Patent number: 6604463
    Abstract: A printing web distortion device for imposing a measured amount of distortion into a moving web of substrate, such as paper, to compensate for lateral stretching of the substrate during a printing operation includes a post, which can be vertically adjusted, having a gas nozzle disposed at, or adjacent to, the tip of the post for generating a cushion of a gas. A support enclosure for the post has a source for pressurized gas. The post is able to slide longitudinally within the support enclosure, so that the tip of the post is either raised in an operating mode, so that the post imposes a stretch compensating distortion or, in an idle mode, the post is withdrawn from the substrate, so that no elevating force is provided on the substrate. In the operating mode, the stretch compensating distortion results from an elevating force provided by the post between the tip of the post and the moving substrate resulting from the cushion of gas, which is preferably a cushion of air.

  • 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: 6357349
    Abstract: A device for feeding web material to a printer that is adapted to accept web from an external roll, adequately align the web with the printer and properly tension the web as it passes through the printer. The infeed device includes a pair of parallel guide rods spaced sufficiently apart to allow passage of the web there between. A pair of edge guides, attached to the parallel guide rods define the web path there through. A spring-loaded pressure pad acts in combination with a smooth metal shoe to tension the web. Further tension is applied to the web as it passes a curved smooth metal surface, just prior to entering the printer. The infeed device allows a wide variety of web materials and web thicknesses to be tensioned and fed into the printer.

  • Patent number: 6334390
    Abstract: A pair of calender rollers are placed before, in a direction of travel of a paper web or paper sheets to a first print unit in a printing device. The calendering rollers improve the quality of the paper web or sheets by rolling particles adhering to the web or sheets into the web or sheets. A paper web tensioning device can be placed between the calendering rollers and the first print unit.

  • Publication number: 20010039892
    Abstract: A device for processing of printing defects detected in a printing machine which in a first phase delivers a printed support. The printing defects (20, 21, 22) on the support (1) are detected in a detection station. A database connected to the detection station can simultaneously store information relating to each detected printing defect. The processing device connected to the database can, in a second phase, process the stored information in order to evaluate the quality of overall printing of the printed support and can use various possible scenarios, even before the support (1) is cut in a third phase, to define all those portions (23) of the support which should be removed in order to improve the final quality of the printed product within the limit of a restriction in the number of portions which it has been agreed to cut out.

  • Patent number: 6298782
    Abstract: A system and method for preventing a broken printing web from wrapping about or otherwise fouling the blanket cylinders of printing press units. The system and method includes a web tensioning device located downstream of the printing press units for maintaining tension upon a broken web and pulling the web from the printing press units. The device includes a plurality of web disturbance detectors for detecting a wave, ripple or other disturbance indicative of a web break. A pair of anti-wrap rollers located above and below the web are engaged upon detection of a web break to engage the web between them to exert tension onto the web and pull it from the printing units. The anti-wrap rollers are rotated at a surface speed nominally greater than the surface speed of the printing rolls. The anti-wrap rollers include a plurality of opposed peak and valley portions which enable them to interlock and grip the web along a line of contact.

  • Patent number: 6295925
    Abstract: In a flexographic tag and label press, a mid-driven infeed tension controlling system is installed between the printing/drying section and the converting section of the press. By creating two separate tension zones, one for printing and one for converting, the mid-driven infeed tension controlling system improves color to color registration in steady state run tolerances, improves make ready times and waste factors, and improves the register of products upon the starts and stops of the press as well as facilitating roll changes and random material roll splices.

  • Patent number: 6279472
    Abstract: A rotary printing press has a postprinting processing station where the printed web of paper, stretched out between two pairs of nip rollers, is slit longitudinally into a pair of web halves and where the web halves are subsequently superposed one upon the other. This station includes a tension roller for imparting tension to the web being slit, and a set of turnbars for causing a change in the traveling direction of one of the web halves before being placed in register with the other. The tension roller and one of the turnbars are both automatically driven to their working positions with the start of machine operation and retracted when the machine is set out of operation.
