Abstract: A machine and a method for controlling such a machine that includes a feeder unit and a sawing station, the feeder unit being located upstream the sawing station. The sawing station includes a first sawing unit including a set of first saw band(s) and a pair of first support rollers, and a second sawing unit including a set of second saw band(s) and a pair of second support rollers, wherein the location of each support roller is adjustable in the transverse direction. The support rollers are configured to engage the timber body. The method is characterized by the steps of feeding the timber body by means of the feeder unit into the sawing station during the timber body dividing operation. The pair of first support rollers engage the timber body, positioning the pair of second support rollers at an initial mutual distance correlating to the real width of the timber body, and decreasing the mutual distance between the pair of second support rollers during the timber body dividing operation until reaching.

Abstract: Method and calculating unit for curve sawing of a block in a cutting direction with at least a first circular saw blade. The method comprises determining a radius of the curve sawing, by measuring the curvature of the block in the direction of cutting; calculating a vertical inclination angle of the first circular saw blade in a vertical plane relative to the cutting direction in the block, based on the determined radius of the curve sawing; inclining the first circular saw blade with the calculated vertical inclination angle; and sawing the block in the cutting direction with the inclined first circular saw blade along the determined radius of the curve sawing.
