SAWLINES – USNR
Sweden: Logmaster HPS
bandsaw line
In 2018
Northern
Forest Owners’ (Norra Timber)
sawmill at Sävar completed the
transformation of its sawline
– touted as the world’s fastest
bandsaw line. The log breakdown
features bandsawing technology,
and the secondary process
includes a new edger line, all from
USNR. The sawline encompasses
a 750E Rotary log feeder, LogPos
S4 log infeed, two ChipCanter
2500 reducing units, and three
Logmaster HPS bandsaws. The line
processes a wide range of timber
in all dimensions, from 120 to 400
mm (5-16”), and log weight can
vary from approximately 70 kg to
one tonne.
“The new production line runs
at its targeted capacity, about
230,000 cubic meters of sawn
lumber annually,” says Johan
Fredriksson, Project Manager at
Norra Timber. “It operates really
well. We don’t have much room for
error, especially with log gaps of
only 40 cm (1.3 ft.).” Johan said he
believes the line can operate at up
to 180 meters/min. (600 ft./min)
with the saw blade speed of 100 m/
sec. (330 ft./sec.).
Another goal was to
dramatically reduce the kerf on the
saws. Johan reported, “Our normal
kerf is 2.8 mm (0.11”) and we have
performed tests with 2.2 - 2.4 mm
(0.086-0.095”) We need more tests
before we get there, but kerfs of 2
mm (0.08”) are absolutely within
reach with these saws.”
Shape Saw.
Wood Trade Company in the
Krasnoyarsk region of Russia has
ordered a circle saw line with
profiling. Delivery will take place
in the spring of 2019 and will
include two ChipCanter 2500s, two
EuroSaw FDP profiling saws and a
Cambio debarking line.
Baikal Wood Company,
operating in the republic of
Buryatia in Russia, has ordered
a comprehensive upgrade of an
existing sawline for increased
speed and lower maintenance
costs. The new equipment consists
of a knuckle log turner and type
448 log infeed, two 240-12 chipper
canters and a 433 cant feeder.
Installation will take place in the
spring of 2019.

LUMBER PROCESSING
The control room at AKD Softwoods offers a birds eye view of the entire log
breakdown line
of Russia. The primary breakdown
is a EuroSaw S4D and the profiling
saw is a EuroSaw FDP, with model
240-12 chipper canters.
USNR offers designs and
configurations for both sorted and
unsorted log operations. Whatever
your processing needs, we’ve likely
already produced a line that is
similar.
New lines on order
Angelina Forest Products is
constructing a new mill at Lufkin,
TX. The new equipment is currently
in manufacturing and the mill is
slated to start up in 2019. The new
log breakdown line will encompass
a reciprocating quad roll log turner,
PGLR (log rotation correction),
canter, profilers, Quad Arbor Saw
Box (circle saws), and Vertical
