DECADES OF HIGHER-QUALITY PRODUCTS

This year marks 70 years since the first mass-produced Cambio debarker was delivered. Since then, nearly 7,000 machines have been built, and the name Cambio has become synonymous with rotary debarkers in many parts of the world.

Cambio revolutionized debarking, which until that point was mostly done manually out in the forest. The new machine was efficient while being gentle on the wood, characteristics that also define the modern machines and which made Cambio appreciated worldwide

The name Cambio comes from cambium, the Latin name for the cell division zone that lies between the wood and the bark. Cambio takes advantage of the fact that the strength here is lower than in the rest of the log.

Many designers in Europe and the United States worked after World War II to develop new debarking equipment because the methods at the time were unsatisfactory. However, the machines that were developed either caused large fiber losses or left bark residue on the log.

Decisive efforts to develop better debarking machines were made at a paper mill in southwestern Sweden. It is a classic inventor story of three men, Erland Andersson, Gunnar Brundell and Karl-Erik Jonsson, setting up a prototype in Andersson’s laundry room. They had to make holes in the wall to feed the logs. After a period of intensive development, a patent application was granted in 1948.

Changing Hands

 In 1951, Söderhamns Verkstäder (now known as USNR AB) acquired the rights to manufacture and sell debarking machines according to the patent from 1948. The machine represented a major technological breakthrough. But it was heavy and complicated and required perfect synchronization of log length and feed rate.

Gunnar Brundell and Karl-Erik Jonsson formed the company Brundell & Jonsson where they continued to develop debarking machines for Söderhamn’s Verkstäder, which led to Cambio. This machine had a large capacity while producing minimal fiber loss. Cambio worked well on all types of wood, even in extreme cold.

The first Cambio was delivered to a customer in 1954 and already by 1956, the annual production was up to 200 machines. Cambio soon became a volume product which, for 20 years, accounted for more than half of the company’s turnover. A dealer network was established around the world. Cambio was made in many sizes for both pulpwood and sawn timber, both stationary and mobile, and is still an important part of the USNR’s product program.

In 1971, Gunnar Brundell and Karl Erik Jonsson received the Royal Swedish Academy of Engineering Sciences’s gold medal for their efforts in the field of debarking.

 The Secret to Success

 What has characterized Cambio right from the start are the triangular feedworks. These ensure that the log is automatically centered in the rotor opening. Since the original designers worked at a paper mill, the quality of the chips was important when developing the machine.

The pointed spikes of the feed rollers provide a good grip on the log while being gentle on the wood as they penetrate between the wood fibers without breaking them. Since the outer parts of a log become chips that are sold to paper mills, it is still important to the sawmills’ overall economy to deliver high-quality chips. The combination of the feed roller’s gentle handling of the logs and the gentle debarking means that the proportion of best quality chips is high with a Cambio.

 Cambio has undergone a series of development stages over the years. From the beginning, the feed speed was modest, about 130 feet per minute (40 meters per minute) as a maximum. Today’s modern machines have the capacity to run more than four times as fast.

Modern Advancements

 In 2000, the first CamShift-type system was delivered. This means that the debarking line is built up in separate modules with independent feed works and rotor units (debarking machines or butt end reducers). The name CamShift refers to the fact that the rotor units can be shifted out sideways to facilitate service and repair. The CamShift system provides, among other things, the possibility of high speeds and the debarking of short logs.s modern machines have the capacity to run more than four times as fast.

Modern Advancements

In recent years, Cambio has gone through a renaissance with several product developments and a clear upswing in new sales.

The name CamShift refers to the fact that the rotor units can be shifted out sideways to facilitate service and repair. The CamShift system provides, among other things, the possibility of high speeds and the debarking of short logs.

 The first model with high-speed ball bearings was the Cambio 600. The bearing, which is of the same type found in, among other things, wind turbines, allows significantly higher rotor speeds. This allows for, in addition to higher feed speed, the bark tools can be opened while running. If the debarking line needs to be stopped while a log is in the rotor, the rotor speed can be After being in trial operation last year with very good results, the Cambio 800AD is now being launched. It is USNR’s largest machine, now equipped with high-speed bearings for increased feed speed and with the same capability as the Cambio 600 to open the rotor during operation.increased so that the debarking tools are thrown out by the centrifugal force.

The Cambio 800D was presented in 2011, where the D stands for direct drive. This means that feed rollers have separate electric motors for operation, unlike previous models that have a motor connected to a chain that drives all the feed rollers. The direct-drive system has many advantages, among other things it means a higher redundancy and simplifies maintenance.

After being in trial operation last year with very good results, the Cambio 800AD is now being launched. It is USNR’s largest machine, now equipped with high-speed bearings for increased feed speed and with the same capability as the Cambio 600 to open the rotor during operation.

CamShift Debarker

The module-designed CamShift system can be delivered with or without flare reducing, and with one or two debarking rotors. The manually adjusted flare reducer rotor is infinitely adjustable for reduced diameters up to 560 mm (22″). The modular, pull-out design makes set-up and tool changes a breeze.

Cambio 800D

With its separately driven feed rolls and newly developed high-speed rotor, the Cambio 800D debarker is designed for high speed and all log sizes. The new rotor and its separate electric motors for each feed roll results in higher feed speed and lower costs for maintenance.

USNR’s new Compact Shape Saw (CSS) system is comprised of multiple modules that work to provide unprecedented performance. This includes the CSS Canter, feed modules, and the CSS Gang.

The centering infeed system has a short lineal footprint that accommodates up to three scan zones and can be fed from either the left, right, or both sides. It operates at speeds up to 650 feet per minute (200 mpm) which is faster than the gang itself, ensuring the infeed will not be a choke point in production.

It centers a cant to the line and then secures it against the sharp-top chain using overhead press rolls. Cants then travel through the scan zones and the optimal solution is determined while the cant travels down the Quickscan Bridge. This bridge can vary in length to fit an existing mill. An overhead anti-roll shoe prevents cants from rolling when entering the Quickscan table.

The press rolls are all hydraulic and feature position and force control which improves overall contact with the piece. This ensures that cants are secured against the bed rolls with a consistent pressure, improving lumber quality.

USNR engineers worked with service experts extensively to ensure the CSS would be built with maintenance in mind. Quick-change press roll and bed roll assemblies allow for spare assemblies to be inserted while the damaged or worn assemblies are removed for maintenance offline, decreasing downtime and increasing the overall reliability of the system. The intermediate and infeed modules can also slide out for easy and safe saw change and maintenance. All cutting tools are easily accessible from either side of the line in the same open area in the center of the line.

Finnish Kesla launched a new generation box-framed KESLA 165 forest trailer at the Agricultural Machinery Trade Fair in Helsinki, Finland 17.-19.10.2024.

KESLA 165 marks the beginning of a new era in tractor-drawn forestry trailers with its robot-welded box-frame-type structure and technical features earlier known from forwarders. The trailer has a standard load space area of 4 m² which can be easily expanded to an impressive 5 m² by simply turning the posts. Together with freely adjustable bunks, hydraulically movable front screen and extendable rear frame, the load space flexibly adapts to varying characteristics of different kinds of round wood. Load space length is 4,8 m which allows 6 m logs, or even longer ones, to be transported safely and efficiently. The new trailer is specifically designed for professional tractor contractors providing increased productivity in logistics and more earnings.

KESLA 165 is the only 167/2013 type-approved forest trailer with 16 tn payload 

Together with a tow bar mounted KESLA 326T timber loader the gross weight of KESLA 165 trailer is totally 22 000 kg consisting of 6000 kg deadweight and 16 000 kg payload. Due to an articulated tow bar and ISOBUS connected traction system the trailer follows the tractor perfectly especially in steep hills and tight turnings. Special attention is put on the bogies which are designed to climb over the obstacles.

Excellent gross weight-payload ratio provides the best fuel economy on the market per transported round wood m3. A powerful nave drive provides an extra 3,9 tons draw power (250 bar and at 2 km/h speed) when required. ISOBUS connected traction system benefits the tractor as the load is well synchronized and therefore causes less stress to the tractor. Trailer comes already from the factory with an EU wide 167/2013 type approval and can be therefore driven legally on the public roads.

 Awarded high-quality workmanship made in Finland

Already prior to its launch, the KESLA 165 trailer received an honourable mention in the New Product Competition organized by the Agricultural Machinery Trade Fair. All KESLA trailers are manufactured in Finland at Kesla Kesälahti plant which celebrated its 50th anniversary this year.

International sales of KESLA 165 starts in December with first deliveries during first quartile of 2025.

REPOST

I explored some ideas in Editors Comment about how to save the rainforest in the June July 2023 issue – (How much money is needed to save the rainforest? ) and Oct Nov 2023 – (The rich can go a long way to saving the planet).

Researching for this article I came across the relatively new #TheEarthFund which was created by a commitment of $10 billion from Jeff Bezos founder of Amazon. After what appears to be relatively quiet start they have recently bounced into action timed to coincide with COP 28 in Dubai.

They announced – WASHINGTON, Dec. 7,2023 /PRNewswire/ – A new data dashboard launched today tracks the collective progress countries have made toward their commitment to halt and reverse forest loss and land degradation this decade. The new platform – the Glasgow Leaders’ Declaration Dashboard – was developed by the Bezos Earth Fund, Systems Change Lab, and the Forest Declaration Assessment Partners, and finds countries are falling woefully short of their commitments to end deforestation by 2030.

Recently published reports, including the Forest Declaration Assessment and the State of Climate Action 2023, find that deforestation increased by 4-7% between 2021 and 2022. The permanent loss of 5.8- 6.6 million hectares (Mha) of forest means that the world is far off course from halting deforestation by 2030. Global efforts to protect other ecosystems aren’t faring much better, with peatland degradation occurring across an area roughly the size of Kenya (57 Mha) and mangrove losses once again ticking upward.

The Earth Fund led by Bezos could be a starting point for serious collection of funds from rich individuals and Governments alike to go towards saving the Amazon and Congo Rainforest.

Referring to Fobes rich list: The United States still boasts the most billionaires, with 735 list members worth a collective $4.5 trillion. China (including Hong Kong and Macau) remains second, with 562 billionaires worth $2 trillion, followed by India, with 169 billionaires worth $675 billion. The amount of money in private hands is staggering. Just as the earth is staggering to a doomsday scenario.

If forest fires continue unabated in 2024 reforestation will never catch up. The earth as we know it could fail by as early as 2030.
