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

Peeling Recovery Productivity Quality Capacity www.raute.com
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 www.raute.com
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 www.raute.com
Veneer Recovery Smart Scan XY block centering + laser curtain www.raute.com
Veneer recovery • Maximized recovery – 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 www.raute.com
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 www.raute.com

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 www.raute.com
• Non-stop stacking • Stacking by – moisture grades – veneer sizes • Stacks prepared for drying Productivity in stacking www.raute.com
Smart Peel makes highest quality veneer • Optimal Peeling Geometry • Precise thickness control • Optimal lathe checks • Consistent peeling www.raute.com
• Rapid block sequencing • Automatic round-up control • Minimum good wood to-good wood time • Non-stop clipping and stacking • High-speed synchronized operation Smart Peel Capacity www.raute.com
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 www.raute.com
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 www.raute.com
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
