Description
Bartly wood knot cleaning machines are specialised industrial units designed to prepare and uniformise the surface of small poles or logs up to 350 mm in diameter. They efficiently remove residual bark, protruding knots and surface irregularities that could compromise timber quality or interfere with subsequent processing stages.
Manufactured in Portugal by Irmach and marketed under the Bartly brand, these machines combine robust mechanical construction, reliable performance and high production capacity, making them ideal for sawmills and industrial units dedicated to wooden stake production.
Processing up to 350 mm diameter
Designed to work with round timber up to 350 mm in diameter, Bartly machines ensure uniform and consistent cleaning, ideal for stakes, fencing posts, agricultural supports and other applications where surface quality is essential.
This processing capacity optimises overall system performance, allowing higher efficiency, reduced mechanical wear and an excellent cost–benefit ratio.
Improved surface quality and finish
By removing knots and irregularities, the machine significantly improves timber preparation for sharpening, fence installation and agricultural use. The more uniform finish increases durability, reduces moisture accumulation points, minimises splinter formation and enhances the final appearance of the product.
Ideal for wooden stake production
The Bartly wood knot cleaning machine is a key piece of equipment for stake producers. Properly prepared timber simplifies sharpening, improves ground penetration and ensures greater dimensional repeatability. It is equally suitable for fencing posts, vineyard supports, agricultural stakes and other roundwood products.
Continuous operation and low maintenance
The industrial-grade structure, high-durability components and optimised transmission systems ensure continuous operation with low maintenance requirements. Wear parts and inspection points are easily accessible, simplifying servicing and reducing downtime.
Integration in production lines
Machines can be supplied with manual or automatic feeding and integrated with debarkers, conveying systems or sharpening machines. Direct integration reduces manual handling and ensures a continuous production flow, increasing overall efficiency and productivity.

Frequently Asked Questions
What is the maximum diameter that can be processed?
Bartly machines process round timber up to 350 mm in diameter, which covers the vast majority of applications such as stakes, fencing posts and agricultural supports.
Is debarking required before knot cleaning?
Yes. The recommended sequence is: debarking → knot cleaning → sharpening (when applicable). The machine is optimised to remove protruding knots and residual bark, rather than large quantities of intact bark.
Does it work with green and dried timber?
Yes, the machine can process both green (freshly cut) and dried timber. For stake production, green timber is often preferred, as it is easier to work and generally results in reduced wear on mechanical components.
Can the machine be integrated into a complete stake production line?
Yes. Bartly machines are prepared for integration with debarkers, automatic feeding systems and stake sharpening machines, eliminating intermediate manual handling and ensuring a continuous and efficient production flow.
