Abstract
Abstract In the manufacture of creped tissue products, the adhesion between the tissue sheet and the creping cylinder can be increased by applying one component of an adhesive complex to the sheet and another component of an adhesive complex to the creping cylinder. When the two components are brought into contact at the pressure roll nip, an adhesive complex is formed which adheres the sheet to the creping cylinder.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
144 words
In a method for making creped tissue wherein a tissue web is adhered to a creping cylinder and dislodged therefrom with a doctor blade, the improvement comprising adhering the web to the creping cylinder with an adhesive complex wherein a first water-soluble component of the adhesive complex is applied to the surface of the creping cylinder and a second water-soluble component of the adhesive complex is applied to the surface of the web such that the adhesive complex is formed when the web is brought into contact with the creping cylinder, said first component comprising a polyacid selected from the group consisting of polyacrylic acid, polymethacrylic acid, ethylene maleic acid copolymer, ethylene acrylic acid copolymer, ethylene methacrylic acid copolymer, styrene maleic acid copolymer, and mixtures thereof and said second component being selected from the group consisting of a polyether, a polyamide, and mixtures thereof.
