THE SUCCESSFULNESS OF SAWMILLING SMALL-SIZED ROUNDWOOD IN CROATIA PART I - SWEET CHESTNUT (CASTANEA SATIVA MILL.)

This research is focused on small-sized roundwood yield factors of Sweet Chestnut (Castanea sativa Mill.). 60 piecess Small-Sized Roundwood were classified in groups according to diameter 15 to 24 cm and sawed by live sawing technique into unedged sawn boards with nominal thickness of 25 mm. All sawn boards were processed into dimension stocks and raw parquet staves by rip-cross sawing. Volume yield of the Small-Sized Roundwood processing into dimension stocks and raw parquet staves was in the range 16.7 % to 41.4 %. Quality yield coefficient of the roundwood processing into dimension stocks and raw parquet staves was in the range of 0.34977 to 0.87923 or 255.33 EUR/m3 to 641.84 EUR/m3 of dimension stocks and raw parquet staves. Log value yield coefficient was in the range 0.06950 to 0.17253 or 50.74 EUR/m3 to 245.15 EUR/m3 of the Small-Sized Roundwood. The results indicate a possibility of rational processing of the researched Sweet Chestnut Small- Sized Roundwood in sawmills.
