Abstract

An active edger includes an actively positionable gangsaw or a first end saw either mounted on an arbor mounted within a stationary saw box, wherein the gangsaw or first end saw is actively positionable relative to the saw box, or mounted on an arbor in fixed translational and skewing relation relative to, and within, an actively positionable saw box. In the latter embodiment the actively positionable gangsaw is selectively actively laterally translatable and selectively actively rotatable so as to skew the gangsaw relative to the saw box. In both embodiments, the saw box receives a workpiece, longitudinally conveyed in a downstream direction, longitudinally into the gangsaw or first end saw from an upstream position. A first chipping head, mounted to a first side of the saw box adjacent and downstream of the first end saw or a first end saw in the gangsaw is, in the first embodiment, selectively actively laterally positionable so as to align with a first feed line corresponding to the first end saw in unison with active positioning of the gangsaw, relative to the workpiece. In both embodiments, the first chipping head actively corresponds, in a lateral chipping depth, to a lateral edging dimension of a sawn edging sawn from the workpiece. The sawn edging is chipped as the workpiece is conveyed from, once sawn by, the gangsaw, longitudinally past the first chipping head.
