  • Patent number: 10569518
    Abstract: The present invention provides a laminator capable of improving evenness of a pressing force applied from pressure-bonding rolls to a substrate and a film. The laminator includes a first pressure-bonding roll, and a second pressure-bonding roll disposed above the first pressure-bonding roll and configured to be displaceable in a direction toward (a first direction) and a direction away from (a second direction) the first pressure-bonding roll. The laminator further includes a support roll configured to support the first pressure-bonding roll below the first pressure-bonding roll, and a pressure application roll disposed above the second pressure-bonding roll. The pressure application roll is configured to be displaceable in the first direction and the second direction, and is also configured to press the second pressure-bonding roll toward one side where the first pressure-bonding roll is located by being displaced in the first direction.

  • Patent number: 6659152
    Abstract: A laminator comprises a pair of pressure rolls 2 having a substrate 1 and a film 55 sandwiched therebetween and bearings 3 adapted to rotatably support opposite end portions of the pressure rolls. One end of a lever 7 is attached to a housing of each bearing. The other end of the lever 7 extends in an axial direction of the pressure roll 2 and is located inward of the bearing 3. A pressure-applying apparatus 14 applies force to the other end of the lever 7, and applies pressure through the bearing to the substrate 1 and the film 55 between the pair of pressure rolls 2. Further, the pressure-applying apparatus 14 generates bending moment which tends to cause the pressure rolls 2 to be projected toward each other. A shaft 16 is disposed in spaced parallel relation to the pressure roll 2. Extension arms 17 are formed in the housings of the bearings 3. The extension arms 17 are connected to the shaft 16, to thereby enable the shaft 16 to support the bearings 3.

  • Patent number: 6367532
    Abstract: In the film holder of a laminator, film sucking bores are arranged so that pitch P2 in the Y direction and pitch P1 in the X direction become gradually smaller toward laminate roll. Therefore, the laminator capable of stably performing the laminating operation even in laminating the rear end of a film sheet can be provided.

  • Patent number: 6320659
    Abstract: A position of an image or shadow of a clearance measuring mark projected onto a plate with respect to a position of clearance measuring mark on a photomask is sensed as image data by a CCD camera and subjected to an image process by a processor. Based on a relative positional relationship between image or shadow of a clearance measuring mark and clearance measuring mark, the clearance between photomask and plate can be adjusted to a prescribed value by a clearance adjusting device. As a result, a clearance measuring device and method can be provided capable of accurately and inexpensively measuring the clearance between the plate and the photomask in the exposure apparatus.

  • Patent number: 6160611
    Abstract: According to an exposing apparatus and an exposing method of the present invention, a photomask is provided with linear patterns having their linear portions to be transferred onto a plate reduced in length. By moving and stopping photomask in one direction of plate and directing light to photomask, the linear patterns are transferred onto plate. Thus, the exposing apparatus and method are provided capable of efficiently transferring the linear patterns onto the plate by exposure using a small photomask.

  • Patent number: 5682228
    Abstract: An alignment apparatus includes holding devices for holding a photo-mask, a supporting device for supporting a substrate, a detecting device, and force-exerting devices. The photo-mask and the substrate have positioning marks, respectively. The detecting device detects positional errors between the positioning marks on the photo-mask and the positioning marks on the substrate. The force-exerting devices apply forces to a periphery of the photo-mask in accordance with the detected positional errors. When receiving forces, the photo-mask elastically deforms in its plane to move the positioning marks so that the positional errors can be corrected to predetermined values.

  • Patent number: 4743325
    Abstract: A method of sticking film sheet on a panel surface is disclosed in which a continuous web of film is cut to proper length fitted to the size of the panel to make an individual film sheet during continuous sticking operation for producing a film laminated panel. The sticking operation is not interrupted by the cutting operation.A laminator constructed to achieve this film laminated panel manufacture includes block members which are movable toward and away from the tacking station where the leading end of the continuous web of film is tacked to the forward end of the panel, and a cutter mounted on the block members. The cutter severs across the film web as the block members moves toward the tacking station in the same direction and at the same speed as the film web during sticking operation.
