Defects in Hardwood Veneer Logs: Their Frequency and Importance

Abstract

Most southern hardwood veneer and plywood plants have some method of classifying logs by grade to control the purchase price paid for logs bought on the open market. Such log-grading systems have been developed by experience and are dependent to a large extent upon the ability of the grader and his knowledge of veneer grades and yields required for the specific product produced by his company. These rule-of-thumb grading systems are often very inaccurate and inconsistent. Manufacturers of both high and low grade veneer recognize the need for a veneer-log grading system that can be easily and uniformly applied. Research agencies and industry have joined forces to solve this problem.
