Abstract: An apparatus (101) for peeling release films (142) used in the manufacturing of liquid crystal display devices includes a winding mechanism for winding a pair of tapes (130) to peel a release film off from a polarization plate (141), a release film peeling mechanism, and a detecting means (120) having a mount (122) and several detectors (121). The detectors are installed on the mount for detecting any deviation of the tape. When a deviation occurs, the relevant detector sends a signal to a control unit (150). The control unit then sends out a signal to a power supply (160) of the apparatus to turn off the apparatus. The control unit also sends out a signal to an alarm device, so as to alert relevant personnel of the occurrence of the deviation.
