METHOD OF MANUFACTURING SECONDARY WHOLE ROLL FOR TISSUE PAPER PRODUCT

摘要

Disclosed is a method of manufacturing secondary whole rolls for a tissue paper product capable of applying chemical solution at low cost and capable of easily switching between application and non-application of the chemical solution. Specifically disclosed is a method of manufacturing secondary whole rolls for a tissue paper product, which comprises a laminating step (51) of forming a laminated continuous sheet (S2) by laminating primary continuous sheets (S11, S12) fed from a plurality of primary whole rolls (JR) in a direction along which the sheets continue; a chemical-solution applying step (53) of applying chemical solution to the laminated continuous sheet (S2); a slitting step (55) of slitting the laminated continuous sheet (S2) into sheets having a width or a several-fold width of a tissue paper product; and a coiling step (56) of forming a plurality of secondary whole rolls (R) having the width or the several-fold width of the tissue paper product by coaxially coiling the slit laminated continuous sheets (S2).
