  • Patent number: 8257638
    Abstract: A suction table 9 is disposed at a cutting action position for a polarizing film F, and holding blocks 9a and 9b, which are different in height from each other, are disposed in proximity to each other along a transport direction on a surface of the suction table 9 to form a suction groove 14. Nip rollers 11 and 12 are disposed on front and rear sides of the suction table 9 to nip opposed ends of the polarizing film F. Further, the suction table 9 suction-holds the polarizing film F in a state that the polarizing film F is inclined with the suction groove 14 located below a portion to be cut. In this state, a laser device 10 scans the polarizing film F along the suction groove 14 to cut the polarizing film F in a width direction.

  • Patent number: 8033364
    Abstract: By rotating a regulating bolt about an axis thereof to move forward/backward with respect to a protrusion portion, a lever is rotated about a shaft portion of an adjusting member. Therefore, the shaft portion of an adjusting member is rotated together with the lever to adjust a gap formed between a disk and a piston. After the gap is adjusted, the regulating bolt is fastened owing to a lock nut and a screw hole of the protrusion portion to thereby fix an forward/backward position of the regulating bolt with respect to the protrusion portion. In addition, a fixing bolt is screwed into a screw hole of a second housing portion to thereby fix a rotational position of the lever. Accordingly, the rotational position of the lever is double-locked.
