Abstract
A method for producing a multi-ply web including at least three plies of flexible material, such as paper and nonwoven material, by means of gluing the plies. The method includes the steps of embossing first and second webs of flexible material separately between a respective embossing roll and a respective impression roll; applying glue to one side of each of the embossed first and second webs; feeding the first and second webs and a third web separately into a laminating nip. The third web is between the first and second webs, and the glue is applied to sides of the first and second webs facing the third web so that the first, second and third webs are combined in a single step. The laminating nip is formed between the first embossing roll and a laminating roll.
