Claim Text:
1. A method for continuously manufacturing liquid crystal display devices, which is adapted to use a strip-shaped film laminate comprising a polarizing film having an adhesive layer formed thereon and being of a width corresponding to one of long and short sides of a rectangular panel, and a carrier film peelably laminated to the adhesive layer, a plurality of transversely extending, longitudinally spaced cut lines being formed in the polarizing film and the adhesive layer, a plurality of polarizing film sheets being defined each between longitudinally adjacent two of the cut lines, each of the polarizing film sheets being classified, based on a defect detected by a preliminary inspection, into either a defect-free normal sheet having a length corresponding to the other of the long and short sides of the rectangular panel, or a defect-containing defective sheet; the method comprising the steps of: feeding the plurality of polarizing film sheets carried by the carrier film, with respect to a plurality of rectangular panels being sequentially conveyed, sequentially toward a lamination position for lamination to each of the sequentially conveyed rectangular panels; using a controller provided for determining whether the polarizing film sheet is a normal sheet or a defective sheet and; when one of the polarizing film sheets is determined as the normal sheet by the controller, positioning a sheet peeling device at a forward, operative position wherein the sheet peeling device acts on the strip-shaped film laminate which is being fed along a first sheet feeding path, to have the normal sheet peeled from the carrier film, and fed to the lamination position so as to laminate the normal sheet to one of the rectangular panels fed to the lamination position in synchronization with the feeding of the normal sheet; and when one of the polarizing film sheets is determined as the defective sheet by the controller, operating a sheet path changing device into an operative position so as to move said sheet peeling device backward apart from the strip-shaped film laminate to thereby direct the strip-shaped film laminate along a second sheet feeding path which bypasses the lamination position, to have the defective sheet fed with the carrier film toward a carrier film take-up position, so that the polarizing film is taken up together with the carrier film, by a predetermined length corresponding to the length of the defective sheet in the feeding direction, wherein operating the sheet path changing device comprises moving each of a plurality of rollers from a first position to a second position.
