INCREASE OF TIMBER OUTPUT WITH HIGH-LOAD CAPACITY BY MACHINE STRENGTHGRADING OF SCOTS PINE HOARDS

The increase of timber output with high load capacity by machine stren gth grading is essential for maximising the value output from German r oundwood. Further it is possible to document the competitiveness of ho me produced timber compared with imported timber from Skandinavia or A merica. Not least the reliable definition of product quality will impr ove the market position of timber against other building materials as concrete, steel or glass. In the study the applicability and reliabili ty of a machine grading system based on the grading criterions MOE in bending, density and knot measurements for Scots pine boards will be e xamined.
