Abstract
A method of making a press felt, a press felt and a base fabric. The base fabric comprises a surface component on the surface facing the paper web to be dried and a base component below the surface component. The transverse jointing edges of the base component are provided with seam loops, by means of which the base component can be connected into a closed loop. At the first jointing edge of the base fabric the surface component extends for a predetermined distance longer than the base component and forms a seam flap that protects the seam area of the base component.
