Abstract:
A board trimmer having pre-trimmer saws comprising a selectively translatable upstream first pre-trimmer saw mounted on a near-side of a board flow path of a board transfer upstream of a downstream multi-saw board trimmer, said pre-trimmer saw selectively translatable by an actuator for translation linearly parallel to a near-side ended board on said board transfer, said pre-trimmer saw perpendicular to said board when on said board transfer, a board elevator mounted below said board flow path and said pre-trimmer saw for elevating said board from a sequence of single boards from said board transfer into sawing engagement with said pre-trimmer saw after said pre-trimmer saw has been pre-positioned by said actuator into a cutting path for optimized trimming of said board in said flow path according to an optimized solution for trimming said board, whereby said board is optimally trimmed by a combination of trimming a first waste portion from a near-end of said board by said first pre-trimmer saw and trimming a second waste portion from either or both of said near-end and a far end of said board by said downstream multi-saw trimmer.
