The Deck Is Stacked

USNR’s Lunden Stickering Stacker is the culmination of design innovation and mill-tested application. The system was popularized by its unique design, and has over 200 in operation worldwide. And now, key advancements have made the USNR Lunden Stacker the fastest and most accurate stickering system available today.

Over 30 years ago Lunden Industries revolutionized stickering stacker systems by producing one of the first Crib stackers. USNR acquired Lunden Industries in 1986, and continues to manufacture 1/3 Crib, Crib, and Conventional style stackers for sticker lengths ranging from 48” to 120”.

In the tradition of innovation, USNR has enhanced the original Lunden design with the patented Quick-Cycle Stickering System and the Break-away Sticker Lifter Arms to create a unique and advanced stacker design that solves many issues common to other systems, like chain stretch, lug timing, stick handling, and maintenance issues. These common stacker problems have been alleviated by the USNR Lunden Stacker.

The USNR system places stickers on the stacker forks and positions the lumber on top of the stickers when the carriage is cycled, resulting in packages of great uniformity with almost perfect sticker alignment. And it’s fast. In green mill applications, USNR has achieved stickering speeds ranging from 10 -18 cycles per minute.

The patented Quick-Cycle Stickering System (QCS) achieves much faster cycle times while operating the sticker system at a slower speed. Relaxed loading and timing requirements make the system immune to chain stretch and other wear related issues. It all adds up to accurate sticker placement every time.

USNR’s patented Break-away Sticker Lifter Arms make it virtually impossible to damage the lifters or the stick pans in the event of a jam caused by a broken stick or board. The spring loaded break-away design allows the operator to clear the jam and reset the lifter arms quickly and safely by hand, no repair tools or extended downtime is needed.

The USNR Lunden Stacker offers a host of other capabilities and options, including course-gapping, random width pullback, sticker unloading (in case of a bowed sticker) and more.

USNR’s commitment to innovation keeps our products at the forefront of leading industry technology. The Stickering Stacker system, for example, uses Allen-Bradley’s Contrologix platform for controls programming. The advantage of using this platform is not only the higher horsepower and faster processors, but its commonality to other systems in the rest of the mill. Machine centers like the Shape saws, High-speed board Edgers and others are all programmed with the same advanced platform, making troubleshooting easier. This commonality lays the foundation for effortless upgrades and opens the door for future MillWide connectivity.

SPLIT SPIKED FEED ROLLS for LOG TURNERS

USNR's Split Spiked Feed Rolls for Log Turners provide several key advantages over traditional one-piece spiked rolls that reduce maintenance time and increase service life.

Longer service life - Why throw out the entire spike roll when the wear is mainly in the center? Now you don't have to, since our split roll segments are symmetric and fully interchangeable, allowing them to be rotated (similar to tires on a car) for more even wear and a longer service life.

Quick Replacement - Why spend hours disassembling your log turner - removing bearings, belts and drive-shafts - when the spike rolls need replacing? WIth USNR's split spike rolls, the bearings, shafts and hubs remain in place during spike roll changes, dramatically reducing maintenance time and expense.
