The yield of sawlogs with the special view upon certain elements of sawing quality

This paper gives a review and analysis of certain investigations carried out so far, concerning the effect of specific factors of processing in sawmills that have an influence on the quantitative and qualitative yield of raw material. The importance of the sawing quality has been emphasized as a significant element in the quality of sawn boards and the volume effectiveness of sawlogs. The investigations of effectiveness of oak sawlogs, that are of a lesser quality, at sawing on the frame saw and head band saw have been described and the results have been given. The accuracy of sawing and the roughness of the sawn surface on boards that had been produced on frame or band saws have been measured and compared. The investigation had been carried out in a limited scope which has made it impossible to generalize the given results. The majority of the results are in line with the data from the references.
