The invention relates to a method (100, 101) for producing a spunbonded fabric (1) and to a device (200, 201) with an embossing pattern (10). In the method, a spinning material (2) is extruded through a plurality of nozzle holes of at least one spinneret (3, 30) in order to form filaments (4, 40), and each of the filaments (4, 40) is stretched in the extrusion direction using a stretching air flow (5, 50), wherein the filaments (4, 40) are laid on a perforated rack (7) of a conveyor device (8) in order to form a spunbonded fabric (1). The aim of the invention is to allow an efficient, technically simple, and inexpensive process of introducing the embossing pattern into the spunbonded fabric. This is achieved in that the perforated rack (7) has an embossing structure (9) with an embossing pattern (10), the filaments (4, 40) are pressed into the embossing structure (9) using the stretching airflow (5, 50), and the spunbonded fabric (1) formed in this manner is provided with the embossing pattern (10).
