A method is disclosed for the production of an air-permeable laminate film with a textile surface and elastic and non-elastic regions. At least one film strip that is elastic in the crosswise direction is introduced, as an elastic insert, between two material webs of fiber non-woven fabric having a web width greater than the width of the film strip. The segments of the material webs made of fiber non-woven fabric that are in direct contact next to the insert are connected, forming a non-elastic region of the laminate film. Subsequently, the laminate passes through an ultrasound bonding station, in which the elastic insert is melted by means of point-shaped bonds, while maintaining the substance of the fiber non-woven fabric, thereby connecting the elastic insert with the fiber non-woven fabric cover layers at discrete points and forming air-permeable structures.
