In today’s sawmilling industry, the difference between staying competitive and falling behind often comes down to how intelligently and efficiently a mill can process every log. Fiber variability, labor constraints, cost pressures, and rising customer expectations are reshaping the way sawmills must operate, and Comact is helping lead that transformation.
With its suite of integrated, high-performance technologies — including the Hybrid Sawline and the TBL4 – Canter, Double Profiler, Curve Sawing Gang Edger — Comact delivers a full-spectrum solution that redefines both primary and secondary breakdown. Together, these two systems form a powerful, intelligent, and adaptable foundation for the mill of the future.
Secondary Breakdown Reimagined: The TBL4
Precision, speed, and adaptability come together in Comact’s TBL4, a high-throughput profiler-gang solution built to meet the demanding needs of modern softwood mills. Designed to maximize recovery and reduce processing gaps, the TBL4 features infeed and outfeed positioning tables that maintain continuous cant control throughout the sawing process.
This continuous flow translates directly into higher throughput and greater yield — exactly what mills need in a high-speed environment.
At the core of the system is Comact’s C2-Scan, a powerful real-time optimization tool that calculates the ideal sawing strategy for each cant. Using both geometric and visual data, the optimizer enables infinite profiling and curve sawing, ensuring every piece is processed for maximum value with minimal waste.
With feed speeds of up to 650 feet per minute and a processing range of 3 to 30 inches wide, the TBL4 offers unmatched versatility. Its fixed-tool design ensures reliability and simplified maintenance, while its compact footprint makes it easy to integrate into existing gang lines, minimizing disruption and capital investment.
The TBL4 also integrates seamlessly with Comact’s digital tools, including OPER8™, Smart Vision, and EverBlue™ services, giving mills a comprehensive platform for tracking performance, driving uptime, and ensuring long-term value.
The Hybrid Sawline: Smarter Primary Breakdown
Paired with the TBL4, Comact’s Hybrid Sawline represents a revolutionary approach to primary breakdown. By combining circular saws and bandsaws in a single, unified system, it eliminates the tradeoffs mills have traditionally faced between speed and flexibility.
Circular saws efficiently handle logs up to 20 inches in diameter with high-speed precision and minimal downtime, while bandsaws kick in for larger logs that exceed circular saw capacity. The result is a line that can process a full spectrum of log diameters without compromise, reducing the need for multiple sawlines and associated maintenance complexity.
But the hybrid sawline is more than just a dual-cutting system. Its design supports multiple cutting modes — including double profiling, quadruple circular cutting, and sideboard splitting — allowing mills to produce a wider range of products on a single line. Whether manufacturing standard 2x4s (100×50 mm) or custom wides, mills gain the flexibility to shift production with market demands, without overhauling equipment or layout.
Intelligence That Runs Deep
Both the TBL4 and the Hybrid Sawline are equipped with Comact’s most advanced smart technologies, turning mechanical cutting tools into real-time decision-makers.
The hybrid system features Smart Vision for log singulation, an AI-powered platform that analyzes each log’s size, shape, and characteristics to optimize feeding and spacing. By dynamically managing log gaps and flow, it maintains consistent production speeds and eliminates bottlenecks, even with irregular fiber supply. This smart control is further enhanced by the C1-Scan, Comact’s primary breakdown optimizer, which determines the best cutting strategy for each log to maximize value from the start.
It also integrates the Primary Breakdown Closed Loop Smart Tool, which automates real-time quality control. Drawing data from the mill’s secondary breakdown scanner, this tool makes precise adjustments during the sawing process to ensure consistent, high-value cuts. With industry-leading response time and dashboard-based alerts, it boosts recovery while reducing operator workload and saw variation allowances.
In the TBL4, the C2-Scan optimizer brings that same level of real-time intelligence to cants. Combined with OPER8TM, this enables mills to visualize production data, track performance metrics, and make smarter operational decisions across the board.
A Cohesive Mill Architecture
What truly makes this combination stand out is how seamlessly each stage connects to the next. Logs enter the hybrid sawline, where they’re processed at optimal speeds using the best-suited cutting method. Cants then transition to the TBL4, where they’re scanned, optimized, and profiled with precision. Downstream, the Curve-Saw Versa Gang takes over, offering accurate curve sawing and adjustable width configurations to extract maximum value from every piece. From breakdown to final gang processing, Comact provides a fully integrated and optimized flow.
The benefits are clear:
- Fewer bottlenecks
- Higher fiber recovery
- Faster product changeovers
- Lower downtime and maintenance costs
- Real-time optimization across every step
And because both systems are modular, digital-ready, and scalable, mills can future-proof their investments while adapting to evolving fiber availability, product demands, and labor realities.
Conclusion: More Than the Sum of Its Parts
Comact’s TBL4 and Hybrid Sawline are more than advanced machines, they are complementary pieces of a next-generation mill architecture that delivers measurable results. When combined, they offer a clear path forward for sawmills looking to increase efficiency, yield, and agility in an increasingly complex industry.
With cutting-edge mechanics, powerful optimization software, and deep integration from log intake to board output, Comact is helping mills unlock the full potential of their raw material and their operations.
