Abstract: The method of manufacturing the secondary paper roll for the tissue paper products including: a multi-ply forming step (51) of multi-ply forming single-sheets S11 and S12 from primary paper rolls, reeled out from the plural primary paper rolls JR in the continuous direction so as to form a multi-ply continuous sheet S2, a chemicals applying step (53) of applying chemicals to the multi-ply continuous sheet S2, a slitting step (55) of slitting the multi-ply continuous sheet S2 into each product width of the tissue paper products or several fold widths thereof, and a winding step (56) of coaxially winding the respective slit multi-ply continuous sheets S2 so as to form plural secondary paper rolls R of each product width of the tissue paper products or several fold widths thereof.

Abstract: Provided is a method of manufacturing a secondary paper roll for tissue paper products, the method being capable of applying chemicals at low cost and easily switching the execution of the application of the chemicals. The method of manufacturing the secondary paper roll for the tissue paper products including: a multi-ply forming step (51) of multi-ply forming single-sheets S11 and S12 from primary paper rolls, reeled out from the plural primary paper rolls JR in the continuous direction so as to form a multi-ply continuous sheet S2, a chemicals applying step (53) of applying chemicals to the multi-ply continuous sheet S2, a slitting step (55) of slitting the multi-ply continuous sheet S2 into each product width of the tissue paper products or several fold widths thereof, and a winding step (56) of coaxially winding the respective slit multi-ply continuous sheets S2 so as to form plural secondary paper rolls R of each product width of the tissue paper products or several fold widths thereof.
