    摘要： Method for manufacturing a tissue product comprises the steps:
    (a) directing a first outer ply into the nip between a first engraved roll running against a first anvil roll;
    (b) directing an inner ply into the nip between a third engraved roll running against a third anvil roll to form an embossed inner ply;
    (c) feeding the embossed inner ply and an un-embossed inner ply towards the first engraved roll downstream of the first anvil roll, wherein either the un-embossed inner ply or the embossed inner ply comes into contact with the embossed first outer ply;
    (d) directing a second outer ply into the nip between a second engraved roll running against a second anvil roll to form an embossed bottom ply;
    (e) feeding the embossed second outer ply towards the first engraved roll upstream of the marrying roll; and
    (f) joining the plies in the nip between the first engraved roll and the marrying roll.
