摘要： A DEVICE FOR DELIMBING FELLED TREES INCLUDING A PAIR OF SHEAR KNIVES WHICH ARE AXIALLY DISPLACED WITH RESPECT TO EACH OTHER AND ARE ADAPTED TO EMBRACE A TREE TO BE DELIMBED. THE SHEAR KNIVES HAVE AN ARC-SHAPED CROSSSECTION AND OPERATE IN THE AXIAL DIRECTION, EACH KNIFE COMPRISING TWO PORTIONS CONNECTED BY A CENTRAL JOINT, WHICH PORTIONS DEFINE A SEMI-CIRCLE IN THE REST PORTION OF THE DEVICE. THE TWO PORTIONS ARE MOVABLE TOWARD AND AWAY FROM EACH OTHER IN A VERTICAL PLANE COMMON TO THE JOINTS AND THERE ARE PROVIDED MEANS FOR CONTROLLING THE MOVEMENTS OF THE JOINTS AND THE ROTATIONAL MOVEMENTS OF THE KNIFE PORTIONS.
