Research of quantitative and qualitative utilization of thin beech round logs

This article presents the results of research on conversion of thin beech logs in diameters from 10 to 25 cms and 1,00 m length. Every class of logs been classified in two subgroups A and B according to method of sawing on primary machine (fig. 3). Quantitative utilization of the group A amounted approximately a 29% for diameters 10-11 cms and 53% for diameters 24-25 cms. Qualitative structure of the obtained assortments: squaire edged lumber length 1,00 rn and 0,50- 0,95 m, flooring strips, broomsticks, squares and packing slats shown in Tables 3 and 4. It is satisfactory, particularly for diameters over 16-17 cms. This paper gives technological aspect of conversion of thin and, short beech round logs.
