ABSTRACT:
A resaw apparatus and method of sawing a succession of boards from a cant of a succession of cants. A band saw is vertically positioned to cut the succession of boards from the cant as the cant is reciprocated through the saw. A pivoted raker gate downstream of the band saw's blade engages the cut board and prevents it from passing through the saw in the reverse direction. A vertically movable live hold-down roller upstream of the saw blade presses down on the cant during sawing. A measuring device measures the cant's height prior to sawing the first board from the cant. When the raker gate moves into its vertical position after the cut board passes, the saw blade is raised slightly to avoid contact with cant splinters on the reverse pass. Each cant is processed to completion before sawing the next cant.
