Sammendrag

Sawmill recovery might be improved by pre-conversion sorting of logs to obtain more homogenous timber quality suitable for specified products. To enhance the knowledge of factors influencing timber quality, 670 spruce trees from 11 mature stands were observed during harvesting and timber processing. By means of factor analysis several knot and resin pocket properties were reduced to two principal components, one representing the knots and another for resin pockets. The number of independent variables are not easily reduced, leaving a possibility of applying several of the characteristics of the logs, the trees and of the stands in finding an efficient log sorting algorithm.

Sammendrag

In the Nordic region, two thirds of a sawmill's turnover is being paid to the forestry sector to obtain adequate roundwood supply. As a consequence, an efficient use of each single log is mandatory for a profitable sawmill. This article discusses a few aspects of this task.
