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.
Claims18
A system for cutting wood, comprising:
- a support with a first portion and a second portion;
- a first pivot member coupled to the first portion;
- a second pivot member coupled to the second portion, wherein the pivot members are aligned along a first axis that passes through the pivot members and said portions of the support;
- a saw box with a top, a bottom, and opposite first and second sides, wherein each of the sides has a respective opening and a respective bushing coupled to the opening, the first pivot member extends at least partially through the bushing of the first side and the second pivot member extends at least partially through the bushing of the second side, such that the saw box is pivotable about the first axis and laterally movable along the first axis relative to the support,
- wherein the saw box is configured to retain one or more saw arbors between the sides in an orientation that is generally parallel to the sides.

A method of sawing boards from a curved log, the method comprising:
- orienting the log such that the curved faces of the log substantially overlie one another along a flow direction;
- conveying the log through a saw box with a plurality of saws arrayed on one or more saw arbors disposed between, and oriented generally parallel with, opposite first and second sides of the saw box, wherein the saw box is movably coupled to a support by a pair of pivot members, and each of the pivot members is coupled to a respective portion of the support and extends through a respective one of the sides of the saw box, and wherein the pivot members are aligned along a first axis that extends through the saw box and the portions of the support;
- and
- while conveying the log through the saw box, tilting the saw box about the first axis and moving the saw box laterally along the first axis to thereby cause the saws to follow the curvature of the log.
