EDGERS – EWD
All centring rollers and several pressure rollers are driven in order to
accelerate the board to a feed speed of up to 420 m/min
The system can process boards
with lengths ranging from 3.7
to 6.3 m. “The sawing height is
between 16 and 55 mm, whereby
Murray’s main size is 44 mm,”
explains Thomas Lang from EWD.
He manages the project at
Murray Timber together with
Project Manager Christopher Wolf.
The unedged board width ranges
from 120 to 550 mm.
After separation, the boards
can be turned on the manipulation
table, cross-cutted or rejected
via a sorting flap, on demand.
The boards are then transported
laterally through the pre-scanning
system. This system determines a
preliminary board shape and open
face, in order to position the board
optimally at the infeed table.

The boards come from the sawing line from the right, these can be trimmed
back (A) or poor quality ones can be rejected via the tipple (B)
for their timber.
Their plants are ideally located
to meet domestic and export
demand. All their construction
timber is kiln-dried and graded in
accordance with NSAI standards
to ensure adherence to specified
moisture content regulation. This is
achieved by using state-of-the-art
drying techniques. Timber is then
regularised on the planing line and
graded to ensure it is of the highest
quality to meet our customers
requirements.
