ABSTRACT:
In an automatic sawmill, a caliper device measures the diameter of an incoming log and the log is then positioned against a pair of backstands over a log receiving carriage. A plurality of cutting devices are positioned relative to the carriage, and the speed control for the carriage is predetermined, in response to the log diameter. The diameter measurement is supplied to data processing circuitry which provides outputs indicative of "sets" to be taken by the aforementioned backstands and cutting devices for sawing the log into a number of cants, boards, or slabs in a manner making optimum use of the log content.
