A system for production of panels, particularly for the production of panels made of wood flakes comprising at least a support plane movable along a direction of forward movement, at least a first and a second forming machine arranged in succession to one another along the direction of forward movement above the support plane and each comprising at least a first set of distributor elements rotatable around respective axes, the distributor elements being able to select a flow of wooden material comprising short flakes and long flakes so as to allow the fall of the short flakes on the support plane and the dragging of the long flakes, where the first forming machine and the second forming machine comprise at least a second set of distributor elements operable independently of the relative first set and where the distributor elements of the first set are operable in rotation in both directions.
