Merchandising for Shape From its sash gang origins of 40 years ago, Shape Sawing has evolved into a sophisticated and varied, high-speed process common in mills today. To understand the full impact and relevance of shape sawing, you must look beyond the processes of a single machine center and embrace a mill-wide perspective. Shape sawing itself has to be examined in the overall context of the mill layout and the production goals of the plant. Though the benefits are good, converting to shape sawing can be expensive considering the building additions that may be required, including concrete, steel, and electrical. Generally the mills best suited for it have high volume production or make specialty products that command a high price. With such considerations, it's imperative that mills are able to reap all the benefits from each of their machine centers. USNR's approach is to coordinate optimization solutions between merchandising and shape sawing. This enables mills to produce logs at the merchandiser that are specifically designed with the exact amount of curvature for products in the cant, and for what downstream machines can achieve. In addition, some products such as wide dimension lumber or timber require limited amounts of curvature. In those instances, logs should be cut with the right amount of sweep at the merchandiser, properly designed for downstream applications.
USNR Optimization also determines the cant's value and profit, how fast it should be processed and how many curve families to fit in. Functions of this magnitude require a state of the art optimization engine, high performance computers, and extremely dense three dimensional data. USNR technology enables mills to accurately execute the solutions projected by the merchandiser at downstream machine centers. |
WELCOME

New Team Member Scott Howard brings to USNR years of experience in the wood processing industry. In fact he first became acquainted with sawmill equipment and processes as a youth in his small family mill. After graduating from the University of West Alabama in Livingston, Scott went on to manage a chip mill that produced chips for local paper mills. He later transitioned into sales. Over the last eight years, Scott has been immersed in the sawmill industry while employed by such companies as Iggesund Tools and Hi-Tech Comact. And now Scott is ready to put his experience to use at USNR. Please join us in welcoming him to the USNR team! |

NEW PROJECTS
|
Anderson-Tully Lumber in Vicksburg, MS is upgrading the V6 Trimmers in both Mill D and Mill K to USNR MillExpert optimization with controls. A. R. WIlliams Materials Handling boasts a history almost as long as Canada's, with roots dating back to 1895 in Ontario as a dealer for machine tools and related supplies. Western expansion in 1942 brought the company to Calgary, Alberta. The company recently purchased a USNR Lift Truck model US-225. Caffal Brothers has placed an order to upgrade the primary and secondary breakdown lines in the Longview, WA mill with new USNR machinery. The mill has purchased a new USNR Vee-Chipper for the primary line along with a sharp chain upgrade. The new gang features a USNR 6" double arbor profiling gang and a USNR chipper canter, with Smart TriCam scanning and MillExpert optimization. Dwight Lewis Lumber of Hillsgrove, PA has purchased a 3D LASAR Carriage optimization system with controls to retrofit the existing carriage. The mill is family owned and cuts Appalachian Hardwoods. Georgia Pacific GLC Controls - Please welcome GLC Controls to the USNR team of OEMs. GLC will act as a value-added reseller of USNR scanning and optimization products in the Northern BC area.
Interfor has ordered a 3D LASAR scanning and optimization system for the Headrig Carriage at their mill in Maple Ridge BC. Maxi Mill will be installing the single LASAR system with Concept Systems doing the PLC setworks. Jordan Forest Products of Barnsville, GA has purchased a dual scan zone TriCam log optimization system with optimized rotation. USNR's scanning and optimization systems can be arranged with dual scan zones to reduce space requirements on lines with short infeeds. ASM will provide various mechanical upgrades and installation assistance. Maley & Wertz owns close to 20 USNR Dry Kilns and has recently ordered a new "high-efficiency" kiln for the Evansville, IN mill. This will enable the mill to efficiently dry a wide range of wood densities. Many newer package kilns today can run almost any drying schedule, but they're only capable of drying a specific density of wood efficiently. Heating systems that are designed to dry a lot of oak, for example, are not generally designed to efficiently dry lighter density species. USNR has developed a "high-efficiency" kiln that uses proportional heat control and venting with modulating actuators to address the different drying needs of various wood species and densities. So now mills can switch from Green Oak to Maple and Poplar and maintain efficient drying without compromising quality. Regulus Stud Mills has bought a USNR 3D LASAR scanning and optimization system for the short-coupled sharp chain line at the mill in St. Maries, ID. Rosboro Lumber Rosboro's first sawmill began operation in 1940 in Springfield, Oregon. Today, along with a stud mill, Rosboro operates several plants that produce a wide range of lumber and plywood products including veneer, plywood and glulam beams. The manufacturing complex now covers 60 acres within Springfield city limits and produces steam for operating veneer dryers, steam vats and the dry kilns. Rosboro Lumber has grown into one of the few integrated forest products operations in Oregon, employing about 400 people. Rosboro Lumber recently ordered a USNR 3D LASAR scanning and optimization system for the dual end-dogging carriage as part of a retooling program to enhance manufacturing efficiency of high quality products. Sierra Pacific has purchased an ELI Conversion for the mill in Quincy, CA. The side shifting infeed line will be upgraded to slewing and skewing and vertical feed rolls will be added. St. Croix Valley Hardwoods specializes in edge glued panels, frame stock and dovetailed drawer parts for the kitchen cabinet and furniture industries. The company operates four divisions in the Mid-West including Dry Kilns, Wood Components, Forest Products and Retail Division. St. Croix Valley Hardwoods recently completed installation and start-up of three new USNR Package Dry Kilns with Kiln Boss Controls in the Luck, WI facility and has retrofitted two existing Dry Kilns in Siren, WI with Kiln Boss Controls. St. Croix recently placed an additional order to retrofit an older unit in the Luck facility with Kiln Boss Controls.
TDC Sawmills of Whangeri, NZ has ordered a USNR 3D TriCam Log Optimization system to be retrofitted on a Hewsaw. TDC manufactures and supplies sawn, processed radiata pine to the domestic market in the Auckland and Northland regions, as well as to the export market in the USA and China. Tolko Industries purchased a USNR Quad Canter upgrade for the large log line at High Level, AB. The upgrade features Smart TriCam scanning, optimization and controls on a new USNR quad roll log turner with auto-rotation. This complements last year's major installation of a complete USNR small log line that included Smart TriCam scanning, optimization and controls for a new Knuckle Turner Infeed and VSS with top and bottom profiling chip heads. |
