<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a curved cardboard sheet which can readily manufacture a curved cardboard sheet having a desired curved shape while maintaining high strength. <P>SOLUTION: The method is for manufacturing a curved both-sided cardboard sheet 60 by laminating a liner 51 on a one-sided cardboard sheet 52. The method includes: a forming step in which a laminate 50 formed by the lamination of the one-sided cardboard sheet 52 and the liner 51 via a paste agent is held between a pair of curved-shaped electrodes 10, 20 so that the entire surface of the laminate 50 is brought into contact along the curved shape of the pair of electrodes 10, 20; and a lamination step in which the paste agent is heated by applying high frequency current to between the pair of electrodes 10, 20 so that the one-sided cardboard sheet 52 and the linear 51 adhere to each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
