World-class log breakdown
designs by USNR
SuperSaver merry-go-round line at Nordwood’s Viiratsi Sawmill, Estonia. A flexible system that manages a broad variety of saw patterns
U
SNR’s expertise in sawing
technology is well known
and respected wherever
modern mills operate and compete
for a slice of the lucrative lumber
market. From high capacity and
performance chipper-canters and
bandsaw lines, to profiling circle
saw lines, USNR has done it all
many times over. Following are a
few of the recent successes and
new orders that prove USNR’s
experience is more than just talk.
Australia: Reciprocating quad
bandsaw line
AKD Softwoods
began its quest for
a new state-of-
the-art sawline
for its main Colac,
Australia operation. The goal
was to lower production costs
through improved productivity
and recovery, and lift flexibility by
enabling a greater product range.
Shane Vicary, CEO of AKD said,
“We recognized that we needed
to invest in efficient, state-of-
the-art equipment to maximize
productivity and recovery to
ensure our operation could be cost
competitive.”
The new line, started in March
2018, includes a reciprocating quad
bandsaw line designed for logs up
to 650 mm (25.6”) in diameter and
down to 150 mm (5.9”), in lengths
up to 6.3 m (20.66 ‘). Design speed
is 16 logs per minute.
The reciprocating sharp chain
transition allows the mill the
flexibility to saw off up to 4 flitches
at the quad bandmill, then stop
the forward motion and back
the cant up to run through for a
second pass, taking off up to 4
more flitches before releasing the
center piece. Shane explained,
“We felt that reciprocation would
give us that additional flexibility
to cut larger logs at Colac, and/or
multiple cant sizes which we could
not do previously, and therefore
conserve capital for other projects.
The line has been running really
well, right from the first day.”
Estonia: SuperSaver merry-
go-round line
Nordwood’s Viiratsi Sawmill,
located in Estonia, installed a log
breakdown line in late 2017. This
SuperSaver merry-go-round line
meets the mill’s requirement for a
flexible system that could manage
a broad variety of saw patterns.
“The main objective of the
investment was to offer forest
owners the opportunity to supply
all the possible assortment of logs
to one factory. The Viiratsi Sawmill
had been a small log mill. Upon
completion of the new line, we can
handle logs with diameters from 8
to 50 cm (3-20”) at the small ends,
and with lengths of 3-6 meters (10-
20’),” commented Tõnu Ehrpais,
Viiratsi mill manager. “We based
our decision on our raw material,
optimum sawing patterns, and the
maximum possible curve sawing
recovery.”
The Viiratsi sawline is a
complete USNR line from the
Cambio 800 debarker to the
resaw and the Catech edger line.
Manufactured in Sweden, the
log line and edger also integrate
USNR optimization and controls,
featuring advanced sweep sawing
optimization for maximum recovery.
