A method and a pressing machine for compressing material (7) consisting of particles so that the material is feeded between press surfaces (1, 1'), whereby the cross-sectional area of the material flow decreases in feeding direction of the material. At least one of the pressing surfaces is formed by parallel transfer elements (1, 1'), like balks, moving back and forth in feeding direction, the larger part of the total pressing surface of which is moving in the feed direction at a time than moving backwards. The speed of return motion of the transfer elements is higher than that of the feed motion.
