  • System for producing veneer from deteriorated core logs
    Patent number: 4239071
    Abstract: A system for producing veneer from deteriorated or hollow core logs. The log is rotated about its longitudinal axis in a lathe by means secured to the log at or near its outer circumferential surface. Two kerfs are cut around the circumference of the rotating log and the veneer blade is then brought to bear against a portion of the rotating log between the kerfs such that a sheet of veneer is cut from that log portion. The length of the veneer blade is no less than the distance between the inner kerf edges and no greater than the distance between the outer kerf edges.
