摘要： A method and a feeding chute for feeding logs (10) into a disc chipper by means of the gravity. The logs (10) are supported laterally by means of adjacent bottom portions (31, 32) of the chute (3) and shoulders between those. The logs are turned parallel with the longitudinal direction of the chute by means of a moment (M) which occurs when the direction of the main axis (27) of the ellipse forming the shearing surface of the log deviates from the direction (27') perpendicular to a the direct line (30) drawn via the rotating centre (28) of the blade disc and the centre (29) of the ellipse. The bottom portions (31, 32) of the chute are inclined around a longitudinal axis in such a way that from two adjacent bottom portions of the chute, the one (31) further away from the rotating axis of the disc forms a bigger angle (β') with respect to the horizontal plane than the angle (β") formed by the portion (32) closer to the rotating axis.
