  • Patent number: 10518495
    Abstract: A cover tape feed device is provided to feed a cover tape onto the surface of a bead core. The cover tape feed device includes a conveyance member that is capable of reciprocating between an advanced position and a retracted position. The conveyance member moves from the retracted position to the advanced position while supporting the cover tape and conveys the cover tape onto the surface of the bead core. The cover tape feed device includes a guide roller for guiding a feed of the cover tape, which is arranged to be rotational at a position farther from the bead core than the conveyance member is from the bead core, and a transmission mechanism that converts movement from the retracted position to the advanced position of the conveyance member into rotation in a tape feeding direction of the guide roller.

    Abstract: A method and a system for producing a printing form for a printing process on a printing press, produces a first printing form based on first image data and prints a printing image on a printing substrate with the printing form. Printing presses without inking zones do not permit regulation of quantitative ink supply with inking zones screws. To permit a printer to manipulate ink density on a printing substrate even after exposure of a first printing plate within a printing press without inking zones, correction values are generated in the vicinity of the printing press in regions on the basis of at least a printing image printed on the printing substrate. The correction values are then used for correcting printing originals on which printing is based and/or screened image data and at least one second printing form is produced on the basis of at least the correction values.

  • Publication number: 20110107932
    Abstract: A platen support mechanism that movably supports a platen unit to which a platen is attached has a platen positioning mechanism that positions the platen unit in a specific posture at four locations, bosses that protrude from both sides at the front in the front-back direction of the printer, and shaft ends that protrude from both sides at the back in the front-back direction of the printer. The platen unit is thereby positioned in a specific posture at the closed position regardless of play in the platen support mechanism. As a result, the platen is positioned to the printing position in a specific posture with a constant gap to the nozzle surface of the print head.

  • Publication number: 20110100240
    Abstract: A printing press includes a printing form cylinder, a blanket cylinder, an impression cylinder, an adjusting device for setting a printing pressure between the blanket cylinder and the impression cylinder, a control device for throwing the pressure of the blanket cylinder on and off relative to the impression cylinder and springs for producing bearer ring pressure between bearer rings of the printing form cylinder and bearer rings of the blanket cylinder. The springs are integrated into coupling links and are connected to at least one of the two devices in such a way that, as a result of the actuation of that device, the springs are also adjusted, in order to keep the bearer ring pressure at least substantially constant.

    Abstract: A method of preparing cylinders for printing on a web during auto transfer operations is provided. The method includes the steps of printing images on a web with at least one first printing cylinder; accelerating at least one second printing cylinder so that the at least one second printing cylinder has a surface velocity that equals a velocity of the web; adjusting a phasing of the at least one second printing cylinder with respect to the web during the accelerating step and before the surface velocity of the at least one second printing cylinder equals the velocity of the web; moving the at least one first printing cylinder away from the web and moving the at least one second printing cylinder towards the web; and printing images on the web with the at least one second printing cylinder. A printing press configured for auto transfer is also provided.

  • Patent number: 7878118
    Abstract: A registration system for a rotary press including circumferential and sidelay registers designed to interface to the press unit using more direct motion translation. In particular, to go from rotational motion of a motor to linear motion of the adjustment with fewer transitions. Also discussed are measurement systems which measure the adjustments made to the plate cylinder more directly by measuring the linear movement of components acting on the cylinder as opposed to the movement of the motor or power source of the registration system. These systems can provide for more accurate movement to the various elements.

    Abstract: A method is presented for automatically controlling the spacing between printer drums. The printer includes at least two print drums (920.1, 920.2) whose parallel rotation leads to image transfer, either between the drums or onto a printed surface. First the pressure a signal indicative of the pressure between the two print drums is obtained by a measurement unit (930), and then the gap between the drums is automatically adjusted in accordance with the indicator signal by a gap adjuster (940).

One plate roll carriage and one anilox roll carriage are operatively attached to the support platform along each opposite side of the support platform by a common linear guide arrangement. The plate roll carriages are positioned along the linear guide arrangements by two plate roll linear positioners operatively attached between the support plate. The anilox carriages are positioned along the linear guide arrangements with respect to the plate roll carriages by a pair of anilox roll linear positioners operatively attached between the plate roll and anilox roll carriages. The support platform is also transversely movable with respect to the printer frame for lateral registration.
