<p>TITLE: METHOD AND APPARATUS FOR PROCESSING TREES INVENTOR: DONALD G. CASTINE A method and apparatus for processing trees in which a clamp holding a severed tree for processing pulls the tree through a set of delimbing blades, while at the same time the blades are moved in the opposite direction along the tree trunk. A system of pulleys and cables driven by a single hydraulic cylinder moves a movable boom and a processing head in one direction relative to a stationary boom, while a clamp assembly is moved in the opposite direction relative to the stationary boom.</p> |
