Abstract
Adhesive (a1, a2) as a pattern of deposits is applied on both sides of a hydrophilic spunbond non-woven inner ply (B) of low grammage and no or low adhesion ability. Together with this inner ply (B) a three ply planar absorbent product is made with tissue outer plies (A,C) by exerting pressure on the adhesive such that the adhesive penetrates through the inner ply (B) for achieving ply bonding between the inner ply (B) and the opposite outer ply (C). The different adhesive patterns do not disturb each other because they do not coincide.
