Disclosed are a method and an apparatus for forming a laminated substrate free from misalignment which would otherwise occur based on the assumption that, when the laminated substrate is formed by; preliminarily producing at least two rolls of laminate webs having different roll widths; and successively laminating at least two film sheets cut out, respectively, from the laminate webs being fed from the rolls, to one surface of a rectangular substrate, the roll width of each of the preliminarily-produced rolls of laminate webs becomes non-uniform. |

1. A method for sequentially laminating, to one surface of a rectangular substrate, at least two different types of film sheets each having a shape identical or similar to a rectangular shape of the substrate, to thereby form a laminated substrate, comprising the steps of:
providing (at least) a first roll formed by winding a first laminated web constructed such that a first film continuously extending in a longitudinal direction thereof and having a width a corresponding to one of a long side and a short side of the substrate is laminated to at least a first carrier film through a pressure-sensitive adhesive layer, anda second roll formed by winding a second laminated web constructed such that a second film continuously extending in a longitudinal direction thereof and having a width b corresponding to the remaining one of the long side and the short side of the substrate is laminated to at least a second carrier film through a pressure-sensitive adhesive layer;
performing, in a first feed line comprised in a lamination apparatus and loaded with the first roll, a process comprising:unrolling the first laminated web from the first roll;successively forming a plurality of slit lines each extending in a direction orthogonal to a feed direction of the first laminated web, in a region of the first laminated web on the first carrier film, in such a manner as to allow a distance between adjacent ones of the slit lines to become equal to a distance b1 corresponding to a preliminarily-measured width of the second laminated web, to thereby form, between the adjacent slit lines, a first film sheet including a pressure-sensitive adhesive layer piece;peeling the first film sheet including the pressure-sensitive adhesive layer piece, from the first laminated web;laminating the peeled first film sheet to the substrate transferred to the first feed line, through the pressure-sensitive adhesive layer piece; andtransferring the resulting substrate to a second feed line; and
performing, in the second feed line comprised in the lamination apparatus and loaded with the second roll, a process comprising:unrolling the second laminated web from the second roll;successively forming a plurality of slit lines each extending in a direction orthogonal to a feed direction of the second laminated web, in a region of the second laminated web on the second carrier film, in such a manner as to allow a distance between adjacent ones of the slit lines to become equal to a distance a1 corresponding to a preliminarily-measured width of the second laminated web, to thereby form, between the adjacent slit lines, a second film sheet including a pressure-sensitive adhesive layer piece;peeling the second film sheet including the pressure-sensitive adhesive layer piece, from the second laminated web; andsuperimposingly laminating the peeled second film sheet to an outer surface of the first film sheet on the substrate transferred to the second feed line, through the pressure-sensitive adhesive layer piece. |
