Abstract
A turning device comprises turning members moveable between an idle position and an operational position, a sensor located upstream of the turning member, for scanning the wood pieces on a conveyor, and an deflector controlled by the sensor and adapted, when actuated, to selectively cause the turning member to be displaced to the operational position for turning a given elongated wood piece on the conveyor to a desired position. The turning member is pivotally mounted to a motorised chain for continuously displacing the turning member adjacent the conveyor. The turning member also includes a guide pin, and the chain drives the turning member along a closed-loop guide track, the turning member having its guide pin engaged in the track.
