Quality lumber drying, sawing logs obtained during parallel to taper
The paper considers the question of quality lumber drying, sawing logs obtained during parallel to taper. It is noted that the issue of quality of drying should be addressed in conjunction with the development scheme of cutting logs into lumber. Orientation of logs in a taper to get more thick and wide boards. According to the literature sources indicated that the quality of timber in some cases higher than that obtained by traditional methods of cutting. Projected higher the strength of the decrease in the cutting of the fibers. It is noted that there is not enough information about what the quality will be such after the passage of lumber production operation chamber drying, how big will the losses due to defects in drying. Take into account that warping internal layer is greater than the outer, while changes in length of the board. Acquires interest in the question of what surface should be taken as a base for machining. Moreover, the allowance for machining because of the gage board width and cross-hogging should be minimal.
