  • Patent number: 8985306
    Abstract: Embodiments provide methods, systems, and apparatuses for loading workpieces in a flow direction into the spaced apart lugs on a lugged conveyor with the workpieces oriented transverse to the flow direction. The lug loader includes an array of pairs of endless conveyors configured to convey workpieces toward a lugged conveyor. The first and second endless conveyors of each pair are spaced laterally apart across the flow direction and aligned substantially in the flow direction. The array can form a continuous or discontinuous transport surface. Some pairs of endless conveyors in the array may overlap one or more other pairs of endless conveyors in the array. At least one pair of endless conveyors in the array may include two or more endless conveyors that are independently driven at different speeds and/or in different directions to de-skew a workpiece.

  • Patent number: 8875414
    Abstract: Embodiments provide a unidirectional multi-path kiln with two or more chambers and generally parallel flow paths extending through the kiln, on opposite sides, from charge entry portals at a first end of the kiln to charge exit portals at a second end of the kiln. Moist heated air flowing from the second heated chamber is received in the first chamber and circulated around the lumber charges with one or more fans. The lumber charges proceed in the same direction on the flow paths through the heated second chamber, which may be an existing kiln. Charge exit portals at the distal end of the kiln and/or intermediate charge portals between the second chamber and a third chamber may be provided with insulating members configured to reduce airflow from the second chamber through the charge exit portals.

  • Patent number: 8794423
    Abstract: The present disclosure provides systems, methods and assemblies comprising one or more tapered feed rolls. Tapered feed rolls may be used to change the rate and direction of workpiece travel along a processing line while retaining the workpieces in sequential order. Routing workpiece flow with tapered feed rolls may allow the workpieces to be tracked along one or more processing lines, and may reduce the operational space required for workpiece processing.
