A method of producing an embossed structure on a workpiece includes applying texturizing components to a carrier surface of a pressing member and causing the texturizing components to form the embossed structure on the workpiece by pressing the pressing member and the workpiece against one another with the carrier surface facing the workpiece. The texturizing components may be connected to the pressing member by gluing, soldering or welding. An apparatus for performing this method includes two pressing belts which are being pressed against the workpiece passing therebetween, at least one of such belts being provided with the texturizing components at an outer surface thereof by an applicator apparatus arranged upstream of the location at which the belts come into contact with the workpiece. The texturizing components may be removed from the belt after each or after several embossing operations.
