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. A computer controls and synchronizes the operations of the various elements. The present saw trimmer may be operated at higher production speed and still performing very good and precise trimmings, compared to previously known saw trimmers.
