Advanced
plate leveller for Precision Metal Processing – High-Tension
straightening machine with Automated Weld Tracking This state-of-the-art plate leveller is engineered for industrial applications requiring precise flatness control in thin metal strips. Designed to eliminate waviness, curling, and residual stresses, this
tension leveler delivers superior straightness and improved material consistency—ideal for manufacturing processes demanding high-quality surface finish and dimensional accuracy. Whether working with carbon steel or similar alloys, the system ensures uniformity across production lines while minimizing waste and enhancing throughput. Key Features: - Dual bending and straightening units for optimal deformation control - Two operational modes: elongation-based stretching and controlled tension leveling - Integrated automatic weld tracking system that pauses at entry point and aligns seam precisely for seamless processing - Hydraulic-driven tension roller group for consistent force application across varying thicknesses - Fully automated unwinder with reverse slow-forward functionality and tail swing mechanism - Oil application unit for lubrication during high-speed operations - Electronic control system with programmable settings for customized processing parameters Detailed Description: The machine employs a multi-stage approach to achieve precision leveling—starting with an upper unwinding method that reduces material handling errors and supports smooth feeding. The strip passes through two bending stations followed by two straightening rolls, where controlled tensile stress is applied to stretch micro-defects out of the material. This process not only improves flatness but also helps reduce yield plateau effects, resulting in more predictable forming behavior downstream. With a maximum coiling speed of 620 meters per minute and a tension capacity of up to 15 tons, the equipment handles both standard and high-strength materials efficiently. A storage table and support arm ensure continuous operation without downtime, while the hydraulic system maintains stable pressure throughout the run. The rewinder includes safety interlocks and synchronization features for reliable spooling after straightening. Ideal Applications: This advanced
stretcher leveler is widely used in industries such as automotive body panel fabrication, appliance manufacturing, construction sheet metal processing, and coil-to-coil stamping operations. It’s especially beneficial for processors who need to convert raw coils into flat, dimensionally stable sheets ready for cutting, bending, or deep drawing. Its robust design and intelligent automation make it suitable for medium to high-volume production environments where repeatability and quality assurance are critical. User Feedback: Operators report significant reductions in scrap rates due to improved edge flatness and fewer rework cycles. One user noted, “We’ve seen a 30% decrease in post-processing defects since installing this tension leveler—it’s become essential for our quality control process.” Another praised the automatic weld detection feature, saying, “It saves hours of manual adjustment every shift.” Frequently Asked Questions: What types of metals can this plate leveller handle? It is optimized for carbon steel within a thickness range of 0.2 to 2.0 mm, though compatible with other ferrous alloys under controlled conditions. How does the weld tracking function improve productivity? By automatically detecting and positioning weld seams at designated exit points, it eliminates the need for manual intervention, ensuring uninterrupted flow and reducing downtime between coil changes. Is the electronic control system easy to operate? Yes—intuitive interface allows operators to set tension levels, speed profiles, and straightening parameters quickly, even without prior experience with similar machinery. Can this equipment integrate into existing production lines? Absolutely—it is designed for modular installation and can be connected to upstream and downstream systems like cut-to-length machines, CNC press brakes, or robotic handling arms.
