Abstract: The saw trimmer is used for trimming lumber pieces. The saw trimmer comprises a conveyor for longitudinally moving lumber pieces across the saw trimmer. The lumber pieces are transversely disposed on the conveyor with reference to the longitudinal direction. A plurality of adjacent drop saw assemblies are located above the conveyor. Each drop saw assembly comprises a circular saw blade parallel to the longitudinal direction, a corresponding hydraulic motor and an actuated positioning system for selectively raising and lowering the saw blade. Each lumber piece is held during the trimming thereof by a retaining assembly comprising a plurality of spaced-apart and parallel elongated rails positioned above the conveyor and extending longitudinally. These rails engage the upper surface of the lumber pieces. A plurality of rolls are positioned under a corresponding rail with an upper edge emerging above the conveyor and are driven into rotation. These rolls engage the bottom surface of the lumber pieces.
