Zusammenfassung:	VARIABLE CURVE LINEBAR ABSTRACT OF THE DISCLOSURE The present invention is a linebar assembly for guiding a cant or log into a saw. It comprises a flexible linebar which can be bent from a straight-line configuration to one approximating a circular arc having a minumum radius of about 30 m. The linebar can be configured into a circular arc which approximates the curvature of a cant or a log having sweep as great as about 100 mm in 5 m of length. The cant is fed into the saw along a circular path to achieve significantly higher lumber recovery. Extended tests have shown that this recovery will be 20-30% greater than that obtained using conventional straight-line sawing methods without any reduction in grade recovery.
