Abstract
Method for producing a multi-ply web comprising at least three plies of flexible material, such as paper and nonwoven material and a multi-ply product produced according to the method. A first and second ply are glued together with a first glue pattern and a second and third ply are glued together with a second glue pattern which, as seen in the thickness direction of the multi-ply web, is substantially aligned with the first glue pattern.
