Machine for dividing a timber body and method for controlling such a machine

A method for controlling a machine for dividing a timber body into a plurality of smaller timber pieces during a timber body dividing operation, wherein the machine comprises a feeder unit and a sawing station, the feeder unit being located upstream the sawing station, and wherein the sawing station comprises:

• a first sawing unit comprising a set of first saw band(s) and a pair of first support rollers configured to cooperate with the set of first saw band(s), and
• a second sawing unit located downstream said first sawing unit, and comprising a set of second saw band(s) and a pair of second support rollers configured to cooperate with the set of second saw band(s),
• wherein the location of each support roller is adjustable in the transverse direction and wherein the support rollers are configured to engage the timber body during the timber body dividing operation,
• the method wherein:
• feeding the timber body by means of the feeder unit into the sawing station during the timber body dividing operation, wherein the pair of first support rollers engage the timber body,
• before the timber body reaches the second sawing unit, positioning the pair of second support rollers at an initial mutual distance correlating to a real width of the timber body, wherein the pair of second support rollers engage the timber body when the timber body reaches the second sawing unit, and
• decreasing the mutual distance between the pair of second support rollers during the timber body dividing operation from said initial mutual distance 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).
