  • Patent number: 10052830
    Abstract: A film tension control system according to an embodiment of the present disclosure includes a delamination unit installed on a transfer path of a polarizing plate to delaminate a release film from a polarizing film, the polarizing plate including the polarizing film and the release film attached to one surface of the polarizing film, an inspection unit installed on a transfer path of the polarizing film to inspect if impurities are present in an adhesive layer formed on one surface of the polarizing film, a tension indication unit installed on a movement path of the release film to indicate a degree of tension applied to the release film, a re-lamination unit to re-laminate the release film having passed through the tension indication unit on the adhesive layer of the polarizing film having passed through the inspection unit, and a tension adjustment unit installed on the transfer path of the re-laminated polarizing plate to adjust the tension of the optical film and the release film.
