ABSTRACT:
A system that rotatively orients and skew positions a log for lumber processing. A log is placed in centering V's and rough centered. Rotatable scan spindles rotate the log while scanners obtain measurements at spaced locations along the log length and at selected rotative positions. Each angular position is analyzed for an optimum cutting pattern and the spindles are rotated to rotate the log into the most desirable angular position. The log is skew adjusted by the scan spindles and/or knee clamps in a carriage and conveyed to a saw array. A computer controls the cutting action to achieve the selected cutting pattern.
