The present invention relates to a timber handling plant (1) comprising a timber sorting station (2) and a method for controlling such a timber handling plant (1), wherein the timber sorting station (2) has an infeed end (3) configured for receiving unsorted timber bodies, and comprises an infeed conveyer (4) extending from the infeed end (3), and a primary sorting apparatus (5). The primary sorting apparatus (5) comprises a first classification unit (6) for classifying each timber body into predetermined classes, and a plurality of primary collecting compartments (7) corresponding to said predetermined classes and each configured to receive all timber bodies of one of the predetermined classes, wherein the primary collecting compartments (7) are located downstream said infeed conveyer (4). The timber sorting station (2) further comprises a secondary sorting apparatus (8) located downstream the primary sorting apparatus (5) and comprising a second classification unit (9) for batchwise classification of each timber body of one of the predetermined classes at a time into temporary sub-classes, and a plurality of secondary collecting compartments (10) corresponding to said temporary sub-classes and each configured to receive all timber bodies of one of the temporary sub-classes.
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. At the end of the timber body dividing operation, a final mutual distance between the pair of second support rollers correlating to the real width of the timber body minus the total thickness of the set of first saw band(s).
The present invention relates to a feeder unit and to a method for controlling such a feeder unit (4) that comprises a pair of support rollers configured to engage a timber body (2), wherein the feeder unit (4) comprises a hydraulic system (12) having a first hydraulic piston assembly (13) connected to a first support roller (14) and a second hydraulic piston assembly (15) connected to a second support roller (16), and wherein the mutual distance between the pair of support roll- ers is adjustable by means of the hydraulic system (12). The method is characterized by the steps of pre-positioning of the pair of support rollers, abutting the pair of support rollers against the timber body (2), by displacing at least the second support roller (16) towards the centre line (18), wherein the first hydraulic piston assembly (13) and the second hydraulic piston assembly (15) are in direct fluid communication with each other and follow any curvature of the timber body (2) and exert the predetermined clamping pressure against the timber body (2).
