Abstract

A method for producing an elastic laminate with at least a first top layer and an elastic film, wherein the first top layer is fed along a production direction to a first stretching device, is subsequently stretched transverse to the production direction by means of the first stretching device and is puckered, and is either connected to an extrusion web provided for forming the elastic film such that the top layer is connected to the extrusion web only by portions facing the melt web or is connected to a pre-produced elastic film in that the elastic film is at least incipiently melted on its side facing the first top layer, the first top layer is pressed against the at least incipiently melted side of the elastic film only by portions, and is therefore at least partially embedded in a polymer matrix of the elastic film.
