The center cant is transported out of the headrig, rotated flat and sawn on a rotary gang edger. This saw makes a series of cuts and can create several boards in one pass.
Because many small logs have sweep (lengthwise bend) in them, modern mill technology uses curved sawing, in which the cant is cut into curved sawn boards. This increases yield, and the curves actually flatten out during the drying process!
