Publication number: 20220339907Abstract: For bonding together two or more plies of cellulose fibers, the plies are fed to a lamination nip between a ply-bonding rotating element and an anvil element. The ply-bonding rotating element has rollers with a cylindrical surface provided with small protuberances co-acting with larger protuberances provided on a cylindrical surface of the anvil rotating element. The plies are bonded, if necessary with the aid of a functional fluid, not containing adhesive, due to the effect of the pressure between the protuberances.Type: ApplicationFiled: September 24, 2020Publication date: October 27, 2022Applicant: Korber Tissue S.p.A.Inventors: Graziano Mazzaccherini, Andrea Petrone, Matteo Galoppini
