SYSTEM AND APPARATUS FOR CUTTING LOGS INTO SHORTER LENGTHS

摘要

A log processing system contains a row of tipple units for supporting a log to be cut into programmed lengths by saws swing-mounted on carriages selectively positioned on a truck extending beside said row. Each tipple unit has two oppositely extending wings each independently moveable between upwardly sloped and downwardly sloped positions. The tipple units at the cutting positions have their wings lowered out of the cutting range of the saws. Log hold-down arms operate fro m the carriages in conjunction with the saws.
