Abstract

A method for the production of a fleece laminate material that has elastic regions and non-elastic regions. In the method, parallel strips of elastic laminate are laminated in between two webs of nonwoven material, at a distance from one another and the nonwoven webs are directly bonded to one another, in the regions between the strips, and form non-elastic regions. The segments of the fleece laminate material that contain a strip, in each instance, form elastic regions. According to the invention, the elastic laminate has a tacky elastomer core layer and at least one non-blocking outer layer of nonwoven material, applied to the tacky core layer.
