  • Patent number: 10317814
    Abstract: A powder supply device that includes a powder reservoir including a rotator having a rotation shaft, to store powder supplied from a powder container; and a powder amount detector. The powder amount detector includes a detected member disposed in the powder reservoir, a contact member attached to the rotation shaft, to contact the detected member to vibrate or move the detected member, a detector to detect vibration or a displacement of the detected member, and a detection result processor to detect the amount of the powder in the powder reservoir based on detection by the detector. The powder supply device further includes a controller to supply the powder from the powder container to the powder reservoir based on detection by the powder amount detector. The controller rotates the rotator in discharging the powder from the powder reservoir and supplying the powder from the powder container to the powder reservoir.

  • Patent number: 7337720
    Abstract: A dual-doctor blade assembly that can accurately meter ink delivery to the anilox cells on the anilox roll of a flexographic printing system. The system utilizes a retractable dual-blade configuration in conjunction with an ink chamber and a gap between the lower doctor blade and the anilox roll. The entire configuration can be adjusted for anilox rolls of various diameters. The upper blade in this system contacts the anilox roll at a point after its rotation through the application tray and scrapes ink from the surface of the anilox roll directly into the ink chamber. As the chamber fills with ink, the hydraulic pressure created by the spinning of the anilox roll increases to a point where the anilox cells are filled to the appropriate volume. The gap created between the lower doctor blade and the anilox roll serves two functions.

  • Patent number: 6895861
    Abstract: Keyless inking systems and methods are disclosed which employs a main form roller and a smaller clean-up roller, both in contact with a rotating printing plate. Separate application and subtractive roller systems control the ink film on the form roller. The clean-up roller removes residual ink from non-image areas on the printing plate. The clean-up roller is in ink communication with the main form roller through a vibrating roller. Mechanisms are provided to selectively engage and disengage the various rollers.

  • Patent number: 6892637
    Abstract: A stamp pad holder for use in a self-inking hand stamp. The stamp pad holder has a stamp die box that holds a stamp forming material, ink cartridge and plastic within the die box. The stamp forming material is placed at the bottom of the die box. A pre-inked ink cartridge is placed above the stamp forming material but separated by an impermeable film. The film prohibits ink from flowing from the ink cartridge to the stamp forming material until the film is pulled from the die box prior to use. This permits the ink from the ink cartridge to impregnate the stamp forming material. The die box is then inserted into the hand stamp. A method of manufacturing the die box is also disclosed.

  • Patent number: 6886460
    Abstract: A method for conditioning a printing ink in a printing press includes providing an ink duct roller and a metering device, operating the ink duct roller in conjunction with the metering device for liquefying the printing ink before a start of printing, and providing a further roller for removing the printing ink from the ink duct roller. Removal of the printing ink from the ink duct roller by the further roller is held in a suppressed state, while simultaneously rotating the ink duct roller at a conditioning rotational speed, and simultaneously controlling the metering device pursuant to a conditioning profile, for only partially opening the metering device at least intermittently. A printing press for performing the method is also provided.

  • Patent number: 6786152
    Abstract: An ink metering system for a roller train in a printing machine which in the illustrated embodiment includes a fountain roller and a downstream train of rollers communicating with a plate or form cylinder of the printing press. One or more plating devices (12) are provided which each have a plate-like element (19) adjustably positionable with respect to a respective roller for leveling ink on the surface of the roller before or after passage through a contact zone with an adjacent roller in which ink is pulled off and separated between the rollers. The plating devices are relatively simple in construction and operation and provide stable ink guidance on the roller surfaces that noticeably improves print quality.

  • Patent number: 6748859
    Abstract: An apparatus is provided which combines an interchangeable ink cassette assembly and a printing press drawer. The ink cassette which includes an ink pan, an anilox roll, and a meter roll may be removably attached to a printing press drawer such that the ink pan and the rolls can be removed as an integral unit from the printing press. Removal of the ink pan and rolls facilitates cleaning of the rolls and the pan. Further, a second assembly may quickly replace the removed assembly to reduce significantly the downtime of the press.
