Abstract:
1. An information storage-readout-calculation system adapted for use in a manufacturing system for continuously manufacturing liquid-crystal display element by laminating sheets of polarizing composite film on a continuous optical film laminate to respective ones of a plurality of liquid-crystal panels, the continuous optical film laminate comprising a continuous polarizing composite film having an adhesive layer thereon and a continuous carrier film releasably laminated to the adhesive layer, the continuous optical film laminate having a width corresponding to either of a long or short side of the liquid-crystal panel, the system comprising; a removable information storage medium storing information of position of at least one defect detected through a preliminary inspection of the continuous polarizing composite film included in the continuous optical film laminate, a roll of a continuous inspected optical film laminate provided with at least one identification means for identifying the continuous inspected optical film laminate, and a slitting position calculation means for determining defective-polarizing-sheet slitting positions and normal-polarizing-sheet slitting positions by using the position information read out from the removable information storage medium based on the at least one identification means and length measurement data calculated based on a feed length of the continuous inspected optical film laminate fed out from the roll, the defective-polarizing-sheet slitting positions and the normal-polarizing-sheet slitting positions defining positions of at least one defect-containing polarizing sheet having at least one defect and defect free polarizing sheets having no defect, respectively, whereby, the defective-polarizing-sheet slitting positions and the normal-polarizing-sheet slitting positions are usable in the manufacturing system of liquid-crystal display elements for respectively defining at least one defective-polarizing sheet and defect-free polarizing sheets by forming slit lines in the continuous inspected optical film laminate in a transverse direction with respect to the feed direction of the continuous inspected optical film laminate at a side opposite to the continuous carrier film to a depth reaching a surface of the carrier film adjacent to the adhesive layer.
