Longitudinal Board Grading at Full Line Speed
ARAS-L BoardScan grades boards as they flow lengthwise through the line — up to 120 m/min, with no lugged chain required. Combining 3D laser triangulation, high-resolution colour imaging, and tracheid scatter analysis, it captures all four surfaces in a single pass and detects grain deviations and hidden knots that cameras alone cannot see. Every board is sorted to its highest market value in real time — on green, dry, or planed lumber.
How ARAS-L Works
Boards pass lengthwise through the scanner frame. All sensors capture simultaneously in one pass — no board turning, no line stop.
Board Entry
The board enters the compact scanner frame in line flow; presence sensors trigger synchronized capture.
4-Sided Capture
3D laser triangulation and colour cameras image all four surfaces simultaneously — no mechanical turning.
Tracheid Analysis
Laser light scattering reveals grain angle deviations and hidden knots invisible to standard cameras.
AI Grading & Sorting
WoodScan AI classifies every defect and assigns the grade; the sorting decision is output in real time.
Every Board Sorted for Its Highest Value
ARAS-L builds a complete defect map of each board — shape, surface features, and internal grain structure — and feeds it to the optimization engine. Edging, trimming, and cross-cutting decisions are calculated against current product values and order priorities, so each board leaves the line as the most valuable product it can become.
WoodScan Trace
Every board knows its log. ARAS-L closes the traceability chain: each graded board is matched back to its source log and position within it, linking board quality to the log data captured at the logyard and sawline.
The result is verifiable, mill-wide data for yield analysis, quality claims, and chain-of-custody reporting — from standing inventory to finished lumber.
Key Benefits
Why mills choose ARAS-L for longitudinal grading lines.
Ultimate Value Recovery
Multi-sensor fusion — colour, laser, and tracheid — identifies every defect, so each board is sorted for its highest market value.
True 4-Sided Scanning
All four surfaces imaged in a single pass, eliminating mechanical board turning and its maintenance burden.
Advanced Tracheid Analysis
Laser scattering detects grain angles and hidden knots — structural weaknesses invisible to standard cameras.
Full Line-Speed Grading
Grades continuously at up to 120 m/min in line flow — the scanner never becomes the bottleneck.
All-Stage Versatility
Reliable grading on green, dry, or planed lumber — integrate at any point in the production line.
Compact Retrofit Design
390 mm shorter mechanical design fits existing decks with minimal downtime and easy maintenance access.
