    摘要： Apparatus for deep incising longitudinal portions of the periphery of wood poles prior to impregnation with a preservative. The apparatus includes an elongate frame including clamps adapted to hold a wood pole between a pair of incising wheels mounted on said frame and adapted to run longitudinally on laterally opposed surface sections of the pole. Indexing means is provided to partially rotate the pole after the incising wheels have completed a run along the pole in one direction and prior to an incising run in the opposite direction. In one embodiment, electronic timing and control means are provided to automatically complete the incising of the entire surface of the pole once it is properly clamped in the machine. The method of deep incising the periphery of a longitudinal portion of a wood pole including clamping the pole; holding the pole between a pair of laterally opposed incising wheels; running said pair of opposed incising wheels along the pole in a first direction; partially rotating the pole; running the incising wheels along the pole in a direction opposite the direction of the first pass; and, repeatedly partially rotating the pole and incising laterally opposed longitudinal sections thereof until the entire periphery of said pole is deep incised.

    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.
