Patent number: 4468993Abstract: A bucking station for small logs is disclosed, in which a log is scanned to determine its size and shape, the resulting data are analyzed by a computer which determines the optimum locations for cuts, and the proposed cut locations are displayed on the log optically for the operator's inspection. If the operator overrides any of the proposed cuts, the computer recalculates any cuts not specified by the operator. When all cuts have been approved, the log is kicked to a cutting bed, where the cuts are made by means of two independently controllable traveling saws. The cutting bed is preferably defined by three sets of parallel plates. The first set comprises stationary plates having V-shaped upper edges which define a V-shaped trough in which the log is initially received. The second and third sets of plates are vertically movable and, when raised, together define a second V-shaped trough located above the first trough.Type: GrantFiled: June 11, 1982Date of Patent: September 4, 1984Assignee: International Paper CompanyInventors: Jack R.
