ABSTRACT:
A method for the feeding of long pieces of wood into a disc chipper against a disc (3) equipped with blades in such a way that the piece of wood encounters the bladed disc at a sharp input angle, and a disc chipper. The sharp input angle is achieved by combining with the sharp inclination (.perspectiveto.) of the feeder chute (5) a sharp level slanting angle, whereupon the inclination of feeder chute (5) will be sufficient to feed wood against the blade disc.
