APPLICATION OF: FOR: METHOD FOR PROCESSING TREES AND APPARATUS USED THEREIN A B S T R A C T An improved method of processing a sheared tree is pro- vided, utilizing an improved processing apparatus. The trunk of the tree is held, by a holding means, adjacent its butt end and the tree trunk is positioned lengthwise of the boom member of the apparatus. A first portion of the tree trunk is delimbed by moving a carriage, including a first delimbing means, along the trunk from the butt end to a first predeter- mined point. The carriage includes a gripping means which grips the trunk at a first gripping point intermediate the butt end and the first predetermined point. The hold on the tree trunk adjacent the butt end is released and a first bolt is bucked (severed), the first bolt being defined generally by the butt end and the first gripping point. A second portion of the tree trunk is delimbed by moving the carriage, the grip- ping means and the tree trunk gripped thereby, relative to a second delimbing means, toward the holding means, the second portion being defined by a gripping point and a second prede- termined point along the tree trunk or the end of the usable portion of the trunk, whichever comes first. The second delimb- ing means is oppositely disposed along the boom member from the holding means. A second topping means is provided for topping a second bolt defined generally by the first gripping point and the second predetermined point, the second topping means being adjacent the second delimbing means along the boom i member. The method and apparatus disclosed herein permits delimbing to occur during both the outward movement of the carriage and the return of the carriage, thus utilizing the entire operational cycle a d permitting the delimbing of a tree trunk substantially longer than the travel of the carriage. ii
