摘要： Nip rollers 11 and 12 each including a pair of upper and lower rollers are disposed on an upstream side and a downstream side with a portion to be cut of an optical film F located therebetween. In the nip roller 12, a center axis C of the upper roller 12b is displaced relative to a center axis L of the drive roller 12a in a direction away from the portion to be cut. Upon cutting of the polarizing film F, the upper rollers 11b and 12b are simultaneously moved downward, so that a timing at which the downstream nip roller 12 nips the polarizing film F is delayed. Further, the nip roller 12 pulls the polarizing film F in the direction away from the portion to be cut, so that tension is applied to the polarizing film F. In this state, the polarizing film F is cut by a laser device 10.

摘要： 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.
