ABSTRACT:
An apparatus for rounding the circumference of a wood log which is supported by two sets of three drive rollers at spaced points between the ends of the log to establish a geometrical center. A knife is positioned extending the length of the log for cutting off a portion of the log for rounding the circumference of the log. The lower rollers are connected together through a shock absorber to accommodate varying diameters and one roller of each set is connected together by a torsion bar. One of the lower rollers of each set is positioned upwardly relative to the other lower roller an amount for allowing the apparatus to provide a maximum yield from different diameter logs. The rollers are of a plurality of self-cleaning, rotatable drive discs. The apparatus may include debarking arms. And the apparatus may sort the rounded up logs by diameter size.
