Sažetak
This paper theoretically and through experimentally researches the performance indicators of sawmill processing of Pedunculate oak (Quercus robur L.) logs in sawn boards. The research covered the sawmilling logs of the oak classified according to the Croatian standards HRN D.B4.028 into two qualitative classes: second and third class. Diameter of processed logs were in range between 30 to 39 cm and 4 m long. Logs were sawn up in the 25 and 50 mm nominal thickness of sawn boards. Automatized line based on vertical log band saw with hydraulic carriage was used for primary sawing up. Secondary sawing was carried out by the classical cross-rip sawing process on machines with individual sawing. Smaller products were made on a band saw and a cross cut circular saw. Quantity yield in live sawing of the oak logs observed in this research was around 57, 29 %, quality yield 87, 89 % and value yield 50, 35 %.
