    Abstract: Bookbinding apparatus adhesive applicator accurately, briefly controls adhesive temperature to a set value by selecting, in accordance with adhesive initial temperature, one of a plurality of temperature-controller heating modes defining different supply powers and supply durations for supplying power to an adhesive-container heater to control its heating temperature. A sensor detects the temperature of the adhesive in the container at applicator start-up, or on restarting a post-standby applicator. In accordance with the detected temperature, one of the heating modes is selected to heat the adhesive. The applicator warm-up time is thus set in response to the state of the adhesive: If solidified, the adhesive is heated and melted in a maximum supply-power, supply-duration mode; if low-temperature liquefied, it is heated and melted in a second-magnitude supply-power, supply-duration mode; and if the adhesive temperature is high, it is heated and melted in a minimal supply-power, supply-duration mode.

  • 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: 8067058
    Abstract: The amount of a paint for forming a porous heat-resistant layer supplied to the outer surface of a gravure roll is adjusted by removing the paint with a blade that is disposed so as to contact the outer surface. A resin blade is used, and the position at which the resin blade contacts the outer surface of the gravure roll is changed as the resin blade wears away. This prevents the amount of the paint for forming the porous heat-resistant layer removed from the outer surface of the gravure roll from changing as the resin blade wears away, so that the excess amount of the paint carried on the outer surface of the gravure roll is removed with good accuracy. An almost constant amount of the paint is thus transferred to an electrode surface from the outer surface of the gravure roll, and a porous heat-resistant layer with an almost uniform thickness is stably formed on an industrial scale.

  • Patent number: 7814860
    Abstract: An adhesive-spreading unit includes a set of rollers, each of which rotates at a higher speed than the preceding one, the first roller being in contact with a tank of adhesive and the last roller sliding in contact with a film on which the adhesive is to be deposited. The unit also includes devices for distancing the rollers from one another and bring them into contact when the film has been loaded into a machine, and a single actuator unit for moving the rollers. The actuator, during the first stage of its travel, brings a rubber-clad roller into contact with the first roller, and during the second part of its travel moves the two rollers to bring the rubber-covered roller into contact with a third roller, which transfers the adhesive to the film and vice versa.

  • Publication number: 20100136243
    Abstract: An apparatus is used to enhance the standing-surfaces of platform-components of an escalator or a moving walkway which moves in a continuous loop. The apparatus is maintained in a constant position relative to the moving parts of the escalator or walkway such that, while in that constant position, all the standing-surfaces continually pass under the apparatus as a result of the continuous loop of the escalator. When the escalator is in operation, an applicator-means of the apparatus applies a flowable enhancement-material, in situ, to the standing-surfaces of the moving platform-components. The material solidifies thereon to enhance the surface characteristics of the standing-surfaces of the escalator, or moving walkway as the case may be.
