Abstract
Log processing apparatus comprises a cutting machine that defines a substantially vertical cutting plane, feed mechanism that feeds a log through the cutting machine in substantially lengthwise horizontal motion parallel to the cutting plane, a measuring station spaced horizontally and vertically from the cutting machine, and transfer mechanism by which a log is carried in horizontal translatory motion from the measuring station to the feed mechanism. At the measuring station, or before the log reaches that station, it is established in an optimum rotational orientation which is thereafter maintained through transfer of support of the log to a set of jaws on the feed mechanism. At the measuring station a relationship is ascertained between a calculated plane that extends lengthwise in the log and a reference plane defined at the measuring station that has a fixed relationship to the cutting plane. The transfer mechanism comprises supporting elements by which a log is confined against all motion except such translatory motion as is imparted to it by the transfer mechanism. The feed mechanism comprises two pairs of jaws, each pair arranged to clampingly grip a log without causing any…
