ABSTRACT:
An apparatus for centering a log to allow an optimum yield axis and a maximum radius of rotation of the log to be calculated more accurately than conventionally possible. The angle of rotation of a log M is detected by a rotation angle detector that is engaged with a preliminary axis c about which the log M is rotated. A contour of the log for calculating the optimum yield axis of the log and a contour for calculating the maximum radius of rotation of the log are measured separately. The contour for calculating the optimum yield axis is measured in a fixed-point manner by measuring the log at a plurality of certain measurement points with beam reflection scanners. The contour for calculating the maximum radius of rotation is measured in a comprehensive manner using swing-angle detectors engaged with contact-swinging detection members provided individually in the plural measurement sections.
