  • Patent number: 10661544
    Abstract: An application method of applying a film F having a main portion 71, an extended portion 72 connected to a first end 71x of the main portion 71, and an extended portion 73 connected to a second end 71y opposing the first end 71x in the main portion 71 to a base material by an application device having an application mechanism, including the steps of: pressing the extended portion 72 using the application mechanism; applying the main portion 71 to the base material by moving the application mechanism that presses the extended portion 72 from the extended portion 72 to the extended portion 73 via the main portion 71; and stopping the application mechanism moved to the extended portion 73 and separating the application mechanism from the extended portion 73.

  • Patent number: 10507634
    Abstract: An application device that applies an adhesive-backed film to a base material having a bonding surface, along a first direction which is an extending direction of the base material, comprises: an application mechanism having an application unit that applies the film from a first end to a second end in the first direction on the base material by pressing the film; and a film gripping part that grips an end portion of the film on the second end side and can be driven in a second direction that is orthogonal to the first direction and is a direction in which the bonding surface and the film are opposed to each other, wherein the application unit presses the film by moving in the first and second directions relative to the base material.

  • Publication number: 20170144421
    Abstract: An adhering device and an adhering method that can check that an article has been pressed at a predetermined pressing force at a predetermined location when pressing and adhering the article to an adhesive surface. The adhering device presses and adheres an article to an adhesive surface. The adhering device comprises a pressure roller having an outer peripheral face that presses the article, at least one projection provided on the outer peripheral face, and a support body that rotatably supports the pressure roller so that a central axis of the outer peripheral face becomes an axis of rotation. Rolling the pressure roller on the article with an appropriate pressing force forms holes on the surface of the article, and it can be confirmed that the pressing was properly performed.
