    Abstract: A log processing head with a top knife and moveable feed means and delimbing and/or debarking means pushing a log against the top knife by means of actuators. In order to allow the top knife to follow the contour of the log without damaging a pin holding the knife, a pivot joint is used between the knife and the connection of the pin on the structure.

    Abstract: Apparatus for handling drive cables and hoses used on a tree processing apparatus (10) wherein a processing head (14) travels along a horizontal boom structure (12). The processing head extend cable system (46) includes a single cable (80) which is attached at one end to the processing head and is reeved over sheaves (66, 68) attached to a hydraulic cylinder output member (55), over stationary idler sheaves (82, 86) over an adjustable idler sheave (84) and is attached at the other end to the processing head. The retract cable system (48) includes a single cable (89) which is attached at one end to the processing head, is reeved over a stationary idler sheave 93, over a sheave (70) attached to the output member (55), and is fixed at the other end to the boom structure. The adjustable idler sheave (84) is attached to a member (92) which can be adjusted relative to the boom to adjust the tension in both cables (80, 89). The hoses (106, 107, 108) which travel with the processing boom are connected at one end to the processing boom and are reeved over stationary idler sheaves (114, 115, 116), over sheaves (72, 73, 74) which are attached to the output member (55), and are attached at the other end to the boom structure. The hose tension is also adjustable by means of the member (92).

    Abstract: A debarking blade arrangement is carried by a frame of a tree harvesting head and includes a fixed knife segment that cooperates with three articulated knife segments carried by each of right- and left-hand, articulated debarking arm assemblies which are disposed on opposite sides of a tree stem feed axis. Each arm assembly includes a rear arm section that carries a first knife segment, an intermediate arm section and a front arm section that carries second and third knife segments and is yieldably biased toward the intermediate arm section so as to dispose the second and third knife segments for engagement with a tree stem. A hydraulically-powered arrangement is coupled to each arm assembly for selectively pivoting the entire assembly about a fixed axis and for pivoting the intermediate and front arm sections relative to the rear arm section for keeping the knife segments in debarking engagement with the stem.
