Embodiments provide systems, methods and apparatuses for positioning boards and other wood pieces in preparation for sawing/trimming. In embodiments, a continuous track loop conveys board stops slideably mounted to board stop guides positioned perpendicular to the direction of flow. A horizontal frame member provides a series of positioning guides through which a cam follower coupled to a board stop is diverted, thus adjusting the position of board stops in a direction perpendicular to the direction of flow without the use of braking devices or other added sources of mass, friction or vibration. 112-. (canceled)13. A positioning apparatus for use with a rotary fence , wherein the rotary fence includes a board stop assembly coupled with a continuous track loop , the continuous track loop is operable in a first direction of flow and the board stop assembly is movable relative to the continuous track loop in a second direction that is transverse to the first direction of flow , the positioning apparatus comprising:a positioning guide with guide surfaces configured to engage the board stop assembly, the guide surfaces including a lateral guide surface oriented transverse to the first direction and a plurality of longitudinal guide surfaces arranged at intervals along the lateral guide surface, the longitudinal guide surfaces defining a corresponding plurality of first lateral positions, wherein the positioning guide is operable to divert the board stop assembly from the lateral guide surface to a selected one of the longitudinal guide surfaces to position the board stop assembly at a corresponding one of the first lateral positions; anda shifting member coupled with a downstream end of the positioning guide, the shifting member configured to laterally displace a downstream end of the longitudinal guide surfaces to move the board stop assembly to a second lateral position between adjacent ones of said first lateral positions.14. The positioning assembly of claim 13 , ...

A board turner assembly may include an endless chain, first and second groups of turning arms pivotably coupled with the endless chain and disposed along opposite sides thereof, an upper guide with an inclined surface, an actuator selectively operable to move the upper guide between a resting position and an extended position, and one or more endless belts. The turning arms may be spaced apart at regular intervals that are offset on one side of the chain relative to the other. The groups of turning arms may be operated in an alternating fashion to turn selected boards to a desired orientation (e.g., wane side up). Corresponding methods and systems are also described. 1. A board turner assembly comprising:an endless chain;a first plurality of turner arms having first and second terminal ends, the first terminal ends being pivotably coupled to the endless chain at first intervals along a first side of the endless chain by corresponding first pivot members; anda second plurality of turning arms pivotably coupled to the endless chain at second intervals along an opposite second side of the endless chain,wherein the first intervals are offset from the second intervals.2. The board turner assembly of claim 1 , further comprising a control system configured to selectively control the first and second groups of turning arms to turn boards in an alternating manner.3. A method of turning a board as described herein.4. A processing line that includes a board turner assembly as described herein and one or more sensors operatively coupled with the board turner assembly The present application claims priority to U.S. Provisional Patent Application No. 62/254,714, filed Nov. 13, 2015, entitled “Board Turner,” the disclosure of which is hereby incorporated by reference in its entirety for all purposes except for those sections, if any, that are inconsistent with this specification.Scanning and optimization techniques are used in some sawmills to determine the best orientation and ...
