Abstract
Apparatus is disclosed and claimed herein for cutting logs into predetermined lengths with primary use in a hardwood veneer plant. A log conveyor is provided, preferably in two sections, with a cutting station located therebetween. The cutting station is equipped with a pivotally operated chain saw or circular saw which cuts the logs as desired. A log clamp means is provided immediately adjacent the cutting station to engage the log on two sides, preferably top and bottom, with the diameter of the log being irrelevant within wide ranges. When a log is first clamped, the cutting saw passes to square off the forward end of same. Located downstream of the cutting station are a plurality of individually operated log stops that are located in the path of travel of the log moving along the conveyor. A particular stop, depending upon the length of log cut desired, is actuated to move into the path of log travel. Upon engaging the stop, log travel ceases, the clamp means are actuated to hold the log, and the cutting saw makes a pass to cut the log. A cut block of a predetermined length is produced. A graduated scale which automatically indicates the diameter of the log being cut may be ass…
