Method of manufacturing secondary paper roll for tissue paper products

A facility for manufacturing a secondary paper roll for tissue paper products, the facility continuously manufacturing a plurality of secondary paper rolls for tissue paper products from a primary paper roll, the facility including:

• a multi-ply forming unit for multi-ply forming single-sheets from primary paper rolls, reeled out from the plurality of primary paper rolls along the continuous direction so as to form a multi-ply continuous sheet;
• a chemicals applying unit for applying chemicals to the multi-ply continuous sheet;
• a slitting unit for slitting the multi-ply continuous sheet into each product width of the tissue paper products or several fold widths thereof;
• and a winding unit for coaxially winding the respective slit multi-ply continuous sheets so as to form a plurality of secondary paper rolls of each product width of the tissue paper products or several fold widths thereof.
