Abstract: A lumber transfer system for transferring pieces of lumber comprising a feeding conveyor having a conveying surface for receiving the pieces of lumber; a plurality of grasping assemblies spaced apart transversely along the conveying surface, each one of the grasping assemblies comprising a grasping finger able to be positioned independently for either grasping a piece of lumber located upstream from the grasping assembly and moving it, or preventing it from grasping a piece of lumber; a detection system for detecting a presence of a piece of lumber and producing signals; and a controller controlling the grasping assemblies for the grasping fingers to be positioned independently. The lumber transfer system is therefore able to have only grasping fingers responsible to grasp the piece of lumber to be in a grasping position.
