ABSTRACT:
A method of laminating a two-ply product wherein the plies are laminated to one another and adhered to a creping surface in the same pattern. A first ply is directed about a patterned pressure and imprinting roll and laminating adhesive is applied to the first ply in a pattern corresponding to the pattern of the pressure roll. A second ply is brought into contact with the first ply, and the composite web is adhered to a creping surface with a creping adhesive at a nip formed between the creping surface and the patterned pressure roll. The composite web is creped from the creping surface in a pattern corresponding to the pattern of lamination. When creped, the densified laminated/creped portions add strength to the resulting product, while between the densified areas the webs are not adhered to one another and the void areas therebetween provide sites for water absorption. In a second embodiment, an endless fabric or belt may be directed about a smooth pressure roll, such that the knuckles of the fabric laminate the plies to one another and adhere the composite web to the creping cylinder in the same pattern.
