            USNR isn’t waiting around for a rebound to happen, they’re determined to help make it happen! They've used this slow period to develop a slew of new cost-effective products that can help reduce operating costs, capture more recovery, and deliver more productivity to mills and the bottom line.

            Replacement items like the new Replaceable-Teeth Sprocket Roll ensures log positioning accuracy while MillTrak effectively replaces dozens of photo-eyes with a single sensor to manage material flow.

            Maybe you need high-speed lug loading? Try USNR's new Gatling Feeder that operates at 320 lugs per minute. If you need higher quality chips from your waste wood, check out USNR's updated Log Chipper. Mills are noticing improved chip quality from this workhorse.

            If you really want to change your game, look at USNR's grading solutions. Advanced products like BioVision and the Lineal High Grader (LHG) bring automated grading to life in the sawmill and the planer mill. See it up close. Most of these items will be on display at WoodTech 2010 – USNR booth # 723.

 

Precision Geometric Log Rotation Ensures the Best Turn on Every Log

            USNR’s Precision Geometric Log Rotation is a real-time rotation verification and correction system that ensures you get the best turn on every log, significantly improving cutting accuracy and increasing uplift and recovery. 

            This new log rotation verification system works on dual or quad roll log turners, donut turners, sharp chain log turners and end dogger systems, enabling you to convert a manual system to a semi-automatic system or a semi-automatic system to a fully automated precision log turning system.

            It uses the same standard TriCam scan zone that the MillExpert Log Turner uses, placed upstream or downstream of the turning rolls to actively monitor and correct the turn during and after the turn.

            The Precision Geometric Log Rotation system simultaneously verifies the accuracy of your autorotation system and automatically makes any necessary correction turns, ensuring you get the best turn on every log.

            This simple solution to an often hidden problem adds profit to your bottom line in the form of higher recovery and increased production of more boards, longer boards and more wane-free boards, all with no extra mechanical hardware! On display at WoodTech – USNR booth #723.

 

MillTrak Controls Lumber Flow with Vision Technology

            USNR’s MillTrak is a vision based material flow management system that maximizes the efficiency of material conveyance through your mill during processing. Mounted above the transfer, the system recognizes the presence or absence of material as well as its width, length, and skew. MillTrak out-performs conventional photo eyes and proximity sensors, and goes far beyond the simplistic present/not present detection. Cost effective and easy to install, MillTrak eliminates the expense of dozens of photo eyes while optimizing lumber flow based on length, width and skew. On display at WoodTech – USNR booth #723.

            Applications for MillTrak include:

            • Planer infeed backlog

            • Log gap control

            • Edger unscrambler feeding a lug chain

            • Trimmer lug loader backlog

            • Cant hook deck sequencing

            • Adaptive hook timing based on product width and skew

            • Stacker layer sequencing

 

BioVisionTM Bolt-on Upgrade Improves Grade in the Sawmill

            Now you can edge and trim for grade without replacing your current scanning system! BioVision™combines color vision with geometric scanning to maximize the value of every board decision based on biological defects, manufacturing defects and configurable grade allowances. It can be implemented with a bolt-on upgrade to an existing transverse geometric scanner, or through a comprehensive installation from the start.

            Why should you optimize for grade?

            • Do you edge for 5/4" decking or reman to 4/4”?

            • A 13’ piece at the trimmer has a knot on one end and wane on the other. What is the correct fence solution?

            • What’s worth more: a 12" board or two 6", or a 4" and an 8"?

            • Two 2x4’s can be worth more than one 2x8, but what if it has large knots?

            • Is it always best to cut-n-two a 20’ into two 10’s, or a 12' and an 8'?

            • Do you want to identify 2x4 clears to be dried separately for export?

            There was a time when almost every mill graded lumber at the edger and trimmer. But as production increased to upwards of 20ppm at edgers and 100+ lpm at trimmers, there was no time to input a grade. Times were good and margins allowed the compromise of production over value. But that was then.

            Today, mills aren’t asking, “How can I make more lumber?” but instead, “How can I make more money at my current production level?”  USNR’s BioVision bolt-on upgrade is the quick payback answer you’re looking for. On display at WoodTech – USNR booth #723.

 

The Lineal High Grader (LHG) Ensures Lumber Packs are on Grade

            Whether your target is to reduce labor costs, control below grade or reduce above grade in your packages, USNR’s Lineal High Grader offers the performance to help you hit your mark.

            The Linear High Grader with DataFusion offers a true technical solution in the quest for fully automated grading. It integrates various complementary technologies to yield a highly accurate lumber grading system.

            DataFusion is the key to successfully integrating multiple technologies to ensure consistent, precise grading solutions. This powerful approach increases the optimizer’s accuracy by confirming the defect type, size and location using two or more independent technologies.

            All vision technology is not equal. Multi-sensor, multi-spectral vision offers advantages over color (or RGB) vision. It detects fiber texture differences between the various vision channels, and allows the sensor architecture to pre-process the image data before it gets to the computer. It gathers less data but more information, resulting in lower computer requirements and faster solution times.

            Additionally, since the LHG is designed to scan the fiber structure and fiber quality, this unique set of technologies provides much more accurate defect detection and thus allows the LHG to meet the market’s most demanding performance levels. On display at WoodTech – USNR booth #723.

            Hit your target with LGH:

            • Reduced trim loss

            • Above grade reduction

            • Below grade control

            • Positive grade distribution shift

            • No lug speed limits

            • No elevation changes

            • ALSC recognized

            • 3000 fpm automatic grading

            • Integrated MSR/MEL

            • Cut ‘N 2, 3 or 4

            • 40+ sold

            • Global installations

            • Graderless

 

Gatling Feeder Operates at  320 Lugs Per Minute

            USNR’s latest achievement in lumber handling is the new Gatling Feeder that runs at speeds up to 320 lugs per minute. This is, without a doubt, the fastest board feeder on the market. Designed for high speed stud mills, the Gatling Feeder will complement other recent advancements in fencing, sorting and stacking. This board feeder is a cost effective solution that allows mills to streamline and significantly increase throughput, while reducing operator intervention.

            • Designed for single-size board applications, such as stud mills

            • Simple design – reliable, low maintenance operation

            • Ultra-fast, operator free lug loading

            • Competitive pricing

            The Gatling Feeder rounds out an already substantial portfolio of board feeders by USNR, an alternate solution to its successful Newtronic, Quad Cam and Revolver board feeder models. This patented design is based on the proven Newnes stick allocator, the feeding component for USNR's slant hopper stick placer system.

 

Replaceable-Teeth Sprocket Rolls Ensure Feeding Accuracy and Reduce Operating Costs

            The overhead sprocket rolls in extended and double length infeed systems play an important part in log positioning accuracy. The sprocket roll teeth grip the log and hold it steady through the scan zone and during transport to the cutting tools. But when the teeth get dull they lose grip, and the log starts rolling and loses position. This significantly decreases the performance of your infeed system. 

            Traditionally the only way to maintain sharp teeth was to replace the entire roll, which is an expensive and time consuming procedure, requiring two men and a crane for several hours. As a result, mills often run sprocket rolls past their prime not realizing it sabotages log positioning accuracy and decreases system performance.

            USNR has developed a solution. Its new sprocket rolls feature replaceable-teeth segments so you can simply replace the worn segments while the roll itself remains installed. Expensive bearings remain intact and the work is reduced to a one-man job with no crane required. On display at WoodTech – USNR booth #723.

            • Replaceable-teeth sprocket rolls ensure feeding accuracy

            • Teeth segments are made of wear plate steel

            • Basic roll body remains installed, saving the bearings

            • One man job, no crane required

            • Segments are reversible if wear is only present on one side     

 

Wastewood Chippers

            USNR has been manufacturing disc chippers for decades, and recent enhancements have made a great design even better. The latest disc chipper is equipped with a kick-out anvil system that complies with stringent mill safety standards. Should a piece of metal enter the chipper, the anvil will kick-out rather than break.

            The chipper also features a new fixed bearing design that reduces “end float”. This design improvement helps maintain the required knife-to-anvil clearances to improve chip quality and also the longevity of the chipper.

            Over and above these safety improvements, mills are very pleased with the quality of the chips the new chipper produces. Better quality chips produce better quality paper.  On display at WoodTech – USNR booth #723.

           

Veneer Dryers

            USNR Veneer Dryers (formerly Coe Manufacturing) consistently produce high quality veneer with a uniform dry moisture content and aesthetic appearance, that is supple enough to minimize damage during the stacking process.

    With the world’s best heat distribution and diffusion system, USNR can better control the thermal air mass in the dryer and increase the production of quality veneer in a cost effective and environmentally friendly manner.

    Energy efficiency is achieved with automatic exhaust controls that result in a more uniform application of thermal mass flow, a lower thermal energy requirement and reduced volume of dryer exhaust.

    One of the most important aspects of the veneer drying process is jet tubes. The heat, speed, even-distribution, and controllability of the jet tubes’ “impinging” air flow defines the efficiency of the drying process and the quality of the veneer that is produced.

            USNR's jet tubes have been produced and refined for over 40 years, the result of thousands of laboratory hours of research and development. The latest jet tube design is based on the strict management and sealing of the airflow that goes into the nozzle, and a very well tested and researched hole configuration that not only speeds up the airflow but ensures a truly perpendicular impingement of the heated airflow onto the top and bottom surfaces of the veneer.

            Customers have reported significant improvement in all cases where older jet tubes were replaced with this new jet tube technology. On display at WoodTech – USNR booth #723.
