Abstract
Embodiments relate to systems, methods, and apparatuses for shape sawing wood. Specifically, embodiments include an infeed with laterally displaceable positioning rolls and a longitudinal axis between the positioning rolls. The embodiments further include a saw box with a frame and a plurality of saws coupled with a plurality of vertical arbors within the frame. In certain embodiments, the frame is operable to move laterally or rotationally with respect to a horizontal axis of rotation.
Claims14
A system for cutting wood, comprising:
- an infeed with a first pair of laterally displaceable positioning rolls and a longitudinal axis extending between the positioning rolls;
- a saw box with a frame, two vertical arbors coupled to the frame, and a horizontal axis of rotation, the two vertical arbors configured to bear one or more saws;
- and
- a first actuator coupled with the frame and operable to move the saw box laterally along the horizontal axis of rotation, wherein the saw box is configured to tilt around the horizontal axis of rotation.
A method of sawing boards from a plurality of curved logs of varying widths, the boards having sawn faces following the curvature of the log including:
- orienting the logs such that the curved faces of the logs overlie one another;
- conveying the logs into and through a saw box with a plurality of vertical arbor saws;
- tilting the saw box via a saw box rotate assembly coupled with the saw box and an outfeed unit, the saw box tilting along a horizontal rotational axis such that the vertical arbor saws follow the curvature of the logs;
- and
- moving the saw box laterally along the horizontal axis of rotation via a first actuator.
