With DataFusion, all of the data collected from scanning – laser profile data, color vision imagery and GrainMap laser mapping – is correlated and verified from one technology to another to ensure the accuracy and reliability of the data. For example, knots require both vision and laser measurement technologies. The vision data gives clues based on the variation in the color of the wood. GrainMap laser mapping measures the deviation of the grain that occurs around a knot. Without the collaboration of data using both of these www.usnr.com | ISSUE 4 - 2013 | Millwide Insider 9

COLLUM'S LUMBER – CLOSING THE GAP appreciation for the role technology plays in today’s marketplace. “With this market the technology is overwhelming. You are either going to stay ahead of the game or get left behind.” Gregg says that he takes a keen interest in new developments and was impressed with USNR’s display when he attended the recent SFPA Expo in Atlanta, GA last June. He said that he was particularly impressed with USNR’s new ElectraTong Lug Loader and will be watching to visit an early installation. For now Collum’s Lumber is reaping the benefits of improved log feeding and increased throughput.

SFPA Show ReviewTechnology on parade USNR brought an abundance of technology for exhibitors to the SFPA-hosted Forest Products Machinery & Equipment Expo held at Atlanta, Georgia June 5 - 7, 2013. Garnering the largest footprint in the show, our booth was a hot spot for visitors to gather to talk about the industry’s latest developments and how USNR’s technology can solve their processing challenges. www.usnr.com | ISSUE 4 - 2013 | Millwide Insider 19

ElectraTong™ Lug Loader It does not require incoming backlog pressure to deal the board. Instead it has the ability to pick up a piece off the infeed belts with no backlog forces. Because no backlog pressure is required it handles feathered edge material well when coupled with a MillTrak backlog camera. The infeed belts index on a board-width basis, allowing it to provide optimum board control at high speeds. ElectraTong is also tolerant of variable thicknesses down the length of a piece, and easily handles feathered boards and waned-out pieces. It will tolerate a wide range of thicknesses between boards (eg. 1” to 4”) allowing it to excel in random thickness green mill applications. It is reliable at high speeds (250+ LPM can be achieved).The industry’s first all-electric lug loader is here! USNR’s ElectraTong Superior designLug Loader is a truly unique solution.
