Moisture Volume Analyzer
• Benefits of accurate veneer moisture analysis and grading:– Accurate dryer control
– Less burnt sheets & less re-drying
– Regained capacity from dryer, less re-drying
– No blows in hot press
– Energy & capacity savings
– Effective production with less post-processing
– Improved yield
– Higher profit
– Savings in glue volume with lower emissions
– Better glue bond & stronger panels
– Improved bending stiffness
– Stronger veneer

• Moisture map
- Moisture map display for each sheet
- Statistics, e.g. average values
- Classification
- Individual moisture value for each
cell
• Moisture value for each area

Green veneer composing

Green Composing principle
Clipping
lines
RandomTrash Sheet cut Tape pieces on both
sides of the veneer
Defects in sheets are
detected by a scanner,
defected parts are cut out by
a defect clipper.
Good parts of veneer sheets
are jointed ”composed”
together with tapes.
The composed veneer mat
is clipped to sheets with
sheet clipper.

Process importance:
Recovery and drying efficiency:
• Green randoms for plywood production instead of chipping to
pulp or fuel.
• Reduced manual labour due to automated handling of veneer
sheets (dryer infeed, dry veneer stacking) instead of randoms.
• Higher dryer efficiency with drying of full sheets only.
www.raute.com
Green Composing principleIn the green veneer composer the clean clipped and aligned veneers
are jointed together with tape (containing thermosetting melamine glue)
applied on both sides of the veneer with the aid of electrically heated
presses, 2x7=14 tape pieces per joint of 5’ veneer .

Defect recognition at Green Composer
Mecano G5 VCO-F• Defects are detected using
combination of the color camera and thickness detectors
– Mecano G5 VCO-composing(Fluoroscope)
– Illumination underneath and above the veneer
– selected color channels are used to recognize certain defects
• Balance with quality and recovery can be adjusted
• Good defect recognition with VCO is important to avoid taping to the surface where the tape cannot bond properly

• Less glue
• Better quality

LVL
Laminated Veneer Lumber
• Continuous lay-up is the heart of all Raute LVL lines
– Raute’s LVL process combines continuous lay-up and cycle press
• Continuous lay-up with pre-pressing produces an endless LVL lay-up, out
of which custom length LVL billets are cut
• From semiautomatic RautePro solutions to fully automatic hands-free
RauteSmart lines.

Lamination effect in LVL
39
One veneer
presents only
5-10 % of the
thickness of
the LVL panel.
Defects in one
veneer sheet
have only a
marginal effect to
the strength of
the whole LVL
panel
www.raute.com
Strength deviations
40
• Strength of LVL is higher
• LVL has much smaller
deviation in strengthStrength
