  • Patent number: 8789491
    Abstract: A cap sheet metal (and pivot sheet metal) is configured to be able to move linearly with a cap arm (and an arm stay) via engagement between an engagement hole and a fitting shaft. Furthermore, the cap sheet metal (and the pivot sheet metal) can move pivotally with respect to the cap arm (and the arm stay) using the fitting shaft, which engages with the engagement hole, as a pivotal shaft. Thus, even if, for example, the direction of biasing toward the applying roller deviates or a positional relationship with the applying roller deviates slightly, the liquid holding member moves and pivots in the bias direction depending on the deviation. As a result, the contacting pressure of a contacting portion on the applying roller can be made uniform.

  • Patent number: 7896966
    Abstract: An applying amount to an applying medium is controlled in a liquid applying apparatus. Specifically, before driving a pump, a circulation speed decision processing (S3) is carried out. According to this decided speed, a speed of the circulation flow generated in a liquid holding space is controlled in a pump operating process (S4). This controls a pressure in the liquid holding space. As a result, a state of flow of the applying liquid at a contact member of a liquid holding member in contact with the applying roller is changed, and an amount of the applying liquid adhering to an applying roller and going out of the contact portion is controlled. This can control the amount of the applying liquid to be applied to the applying medium.

  • Patent number: 7445693
    Abstract: Two axially parallel rolls are pressed against each other in a device for producing and/or treating a moving material web. Sensor elements are arranged in the force transmission path running from the force-producing elements via the rolls, outside roll bodies of the two rolls. As a result of displacing the sensor elements out of the roll bodies of the rolls, the production of the rolls is less complicated and less expensive. No sensors have to be embedded in the roll bodies, which opens up the possibility of using standard rolls. In addition, the occasional grinding of the rolls can in this way be performed without any regard to the sensor elements. Nevertheless, the pressure prevailing between the rolls can continue to be measured directly, since the sensor elements are arranged in the transmission path of the pressing force.

  • Patent number: 7323056
    Abstract: A coating apparatus is provided in which entrained air flow of an applicator roll and a web is removed and occurrences of misting and coating irregularity are suppressed to thereby realize a uniform coating liquid film and a uniform coating state. A coating apparatus includes an applicator roll arranged to abut on another roll so as to form a nip portion therebetween and to transfer a coating liquid to be coated on a surface of a web passing through the nip portion. The coating apparatus further includes a coater head provided on an upstream side of the nip portion in a rotational direction of the applicator roll so as to supply the coating liquid onto a surface of the applicator roll and a boundary air remover provided between the nip portion and the coater head on the upstream side of the nip portion so as to prevent air from entering the nip portion.

  • Patent number: 7211151
    Abstract: A coating liquid application apparatus is provided which can apply a coating liquid, such as a coating agent for improving a weatherability of a printed surface, to the printed surface of a print medium automatically and at high speed. For this purpose, this invention uses application mechanisms to apply the coating liquid to the print medium that was ink-printed with an image. Each application mechanism has a pair of rollers supplied with the coating liquid. Multiple stages of such application mechanisms are provided. The print medium is passed between the paired rollers successively from one application mechanism to another to apply the coating liquid to the print medium in a plurality of stages.

  • Patent number: 7056385
    Abstract: A paper dispenser for the optional distribution of saturated or dry paper from a paper roll or a folded paper sheet. A container filled with fluid is arranged in a housing from which the fluid is conveyed against the paper sheet to be moistened and is activated by a feed drive. In order achieve a more operationally secure transport of the paper sheet the intention is for the paper dispenser to have a hand-operated conveyor apparatus for the conveyor drive of the paper sheet. The fluid is conveyed from one of the extraction cylinders submerged in the fluid bath to one of the transfer cylinders loading onto one of the extraction cylinders, which is arranged on at least one side of the paper sheet.

  • Patent number: 7018475
    Abstract: Two axially parallel rolls are pressed against each other in a device for producing and/or treating a moving material web. Sensor elements are arranged in the force transmission path running from the force-producing elements via the rolls, outside roll bodies of the two rolls. As a result of displacing the sensor elements out of the roll bodies of the rolls, the production of the rolls is less complicated and less expensive. No sensors have to be embedded in the roll bodies, which opens up the possibility of using standard rolls. In addition, the occasional grinding of the rolls can in this way be performed without any regard to the sensor elements. Nevertheless, the pressure prevailing between the rolls can continue to be measured directly, since the sensor elements are arranged in the transmission path of the pressing force.

  • Patent number: 6955721
    Abstract: A coating apparatus for applying a coating liquid to a printing substrate. The coating apparatus has a rotatable first roll and a rotatable second roll, each having a surface energy. The second roll is positioned adjacent to the first roll and defines with the first roll a first nip through which the printing substrate passes A metering device is provided for applying a substantially uniform layer of coating liquid onto the second roll. The second roll in turn transfers the coating liquid to the printing substrate. The surface energy of the second roll is greater than the surface energy of the coating liquid. In one embodiment, the metering device includes a rotatable third roll and a doctor blade contacting the third roll, each having a surface energy. The surface energy of at least a portion of either or both the third roll and doctor blade is less than the surface energy of the coating liquid.

  • Patent number: 6849124
    Abstract: An improved method and system for cleaning a cylinder of a printing press. One method involves soaking a strip of cleaning fabric on a press with a low volatility organic compound solvent. Excess solvent, if any, is removed to place the strip of cleaning fabric in functional equilibrium with the solvent. The cleaning fabric is then used to clean a cylinder. Alternatively, the strip of cleaning fabric is soaked on site by contacting the strip of cleaning fabric with the solvent and wrapping the strip of cleaning fabric into a cleaning fabric supply roll. The cleaning fabric is then brought in engagement with a printing press having a cylinder to be cleaned without disposing a sleeve around the fabric roll and without substantially disturbing the distribution of the solvent in the fabric roll and detrimentally affecting the cleaning ability of the fabric.
