<P>PROBLEM TO BE SOLVED: To solve manufacturing trouble such as contamination of a manufacturing machine or degradation of finish quality in manufacturing a packaging container by preventing and suppressing generation of dust or paper powder, in cutting of a composite wrapping material sheet, in particular, a composite laminate wrapping material sheet composed by laminating heterogeneous films different in hardness or rigidity such as a paper sheet layer for an intermediate layer and a resin film layer(s) on one surface or both surface sides. <P>SOLUTION: A composite laminate sheet A is introduced into sheet heating means 7, 8 to heat the front surface or/and the back surface of the sheet A to soften a resin film layer 2 located on each surface layer on the front surface side or/and the back surface side by the heating; and thereafter the sheet A is introduced into a cutting means B and cut by a blade part heated by blade part heating means 11a, 12a mounted on the cutting means B. <P>COPYRIGHT: (C)2013,JPO&INPIT |
