Newest technologies and possibilities in peeling process of smaller dimension logs
by Mr. JP Salimäki Area Sales Manager

2. From blocks to Plywood

3. Smart Peel Technology

4. Maximized performance:
The Raute Formula
Maximized performance:
(recovery + productivity + quality) x capacity
= profitable panel production

5. Raw material flow (Example)
Process Phase
Recovery
volume m 3 /a
Logs (over bark)
115% -
less bark
Debarked logs
100%
less cutting loss
Peeler blocks
95%
less round up
less cores
less spur
less clipping
95.000
Green veneer
65%
65.000
How to utilize side products? Fuel for burning Particle Board etc. Pulp Bark ~15% ( m3/a) Other side products ~35% ( m3/a)
Cooking:
Equalize desity variation
Knots shoft (high speed possible, knives last better)
Better surface (less tear-out, when gross grain peel)
Possible to use sharper knives ( deg.)
Possible to use negative pitch angle
= small , ”tilted” cracks = strong veneer = less glue consumption
high temperature boils resin out

6. Profitability elements
Peeling
Plywood quality
Wood recovery
Glue savings
Production of Plw
XY Centering of Block
LVL
Smart Peel lathe
Rotary clipper
Green stacker

8. Prepare your wood properly
Clean logs from bark and dirt
Conditioning improves veneer quality
Trim and cross cut log to optimum peeler block length
Feed fresh cut blocks to peeling

9. Process importance
Log handling is an important logistical and preparative operation that ensures a mills’s trouble free production
Well prepared peeler blocks contribute to best recovery and veneer quality
Different raw materials require an individual approach when designing the wood flow from log yard to peeling
Heavy duty equipment suit best for all challanges
By-products such as bark and wood residuals need to be handled optimally in all lines

10. Veneer Recovery
Smart Scan XY block centering + laser curtain

11. Veneer recovery Maximized recovery Maximized value Minimized randoms
Critical for profitable small block peeling
Maximized value
Highest value veneer is on block surface
Minimized randoms
50 % of randoms will be lost later in production

12. Smart Peel maximizes productivity
Features of small diameter peeling line:
Smart Peel lathe deck
Clipping trash gate
Catch up tray system
Moisture grading
Stacking by grade

14. Productivity by proper moisture grading
Moisture has a major impact of productivity and quality
Moisture grading before drying ensures more consistent drying, reduces drying time and reduces redry
Clipping veneer according to moisture content saves raw material and downstream manufacturing costs

15. Productivity in stacking
Non-stop stacking
Stacking by
moisture grades
veneer sizes
Stacks prepared for drying

16. Smart Peel makes highest quality veneer
Optimal Peeling Geometry
Precise thickness control
Optimal lathe checks
Consistent peeling

17. Smart Peel Capacity Rapid block sequencing Automatic round-up control
Minimum good wood-to-good wood time
Non-stop clipping and stacking
High-speed synchronized operation

18. Non-stop functions to increase capacity
Clipping trash gate eliminates carriage retract after round-up
Eliminates leading edge taper
Reduces good-wood-to-good-wood time
Reduces random and trash handling

19. Operator ergonomics and efficiency
Joystick controls for charger and lathe
All basic functions without changing the grip
Touch screen “heart of process control”
Offset setting
Peeling program download and saving
Peeling and clipping speeds
MIS input
Easy to use
Always in operator’s language

20. Conclusions
Raw material recovery is maximized with Raute Smart Peel concept
All line solutions are taylorized to enhance productivity
Raute’s product family enables numerous different solutions to meet the customers’ overall requirements
World wide expertise in peeling different wood species
Raute’s proven formula for the profitable production of wood products
recovery
quality
productivity x
capacity =
profitable production
