The TW‑420A is a precision-engineered band blade skin (leather splitting) machine, designed for use in footwear, leather goods, and upholstery production. Manufactured by Tai Wei in Zhejiang, China, it's a high-performance, semi‑automatic splitting unit that delivers consistent thickness, reliable operation, and long-term dependability.

Core Advantages & Operational Efficiency

Optimized Splitting Precision with Digital Control TW‑420A features a digital display for exact thickness adjustments. Operators can input the exact desired split—ranging from as thick as 8 mm down to 0.5 mm (with roller feed), or as precise as 0.15 mm (using top bar). This level of precision ensures uniform material thickness, critical for high‑end footwear uppers, soft midsoles, and leather skins used in premium accessories. 

Stepless Feed Speed with Smart Registration The integrated stepless speed control allows an adjustable feed rate (approximately 1–20 m/min), tailored for various leather types—from soft garment leathers to stiffer cowhide—eliminating jerky feeding or inconsistent cuts while maintaining material integrity. The automatic registration device ensures the knife and feed action remain perfectly aligned, removing the need for manual knife tracking adjustments. 

Smart Pressure Pad Adjustment TW‑420A automatically regulates the pressure pad clearance to ensure even contact and consistent thickness throughout large panel runs. This adaptive response yields stable results regardless of thickness variations or material softness.

Lubricated Precision Mechanics Critical moving components—including slide rails, bearings, and gear assemblies—have lifetime lubrication, cutting maintenance downtime and extending machine life. The internal structure is designed for smooth, vibration-free operation at under 70 dB—important where factory noise levels affect worker comfort.

Heavy-Duty High-Length Band Knife At the heart of the TW‑420A is its 3 500 mm × 50 mm × 0.7 mm band knife—made of durable alloy steel to offer consistent sharpness over prolonged production runs. The long blade reduces knife change frequency, lowering operating expense. 

Precision Guide Roller & Linear Bearings Material is guided by robust rails and linear bearings, ensuring smooth movement and knife stability—translated directly into neater, cleaner splits and consistent quality.

Blade Grinding & Dust Extraction Included A built-in blade grinder (compatible with both corundum and diamond wheels) means you can maintain sharp edges on-site. It’s paired with an independent dust extraction unit to eliminate grind debris and keep the blade clean—extending its life and performance. 

 Layout That Maximizes Usability & Safety

Ergonomic Design The work table sits at a user‑friendly height, minimizing operator fatigue during long production cycles. Cleanup and servicing are straightforward, thanks to easy access to internal parts like hydraulic pumps, motors, and filters.

Low Noise, Clean Environment With operational noise levels below 70 dB, TW‑420A creates a cleaner, more comfortable work setting. The closed dust extraction system also ensures a safer, low-dust environment—critical when processing leather or synthetic materials. 

Advanced Safety Features The machine is equipped with an auto-stop system that immediately halts operation if material becomes tangled in the blade. An electronic phase detection system will also shut down the device in case of power phase irregularities—protecting operators and equipment.

 Productivity & Cost Benefits

High Throughput & Consistency The automated feed and pressure controls allow operators to produce large batches of consistent splits with minimal supervision—optimizing labor use and reducing rework.

Reduced Material Waste Precise thickness control and minimal kerf result in maximum material yield—ideal for high-cost leather.

Save on Consumables The long-lasting knife and built-in grinder reduce blade replacements. The intelligent dust extraction and lubrication preserve blades and critical mechanics.

Lowered Operational Overhead Multi-layer safety systems reduce downtime. Easy access to components cuts maintenance time. The grinder and cleaner mean fewer external servicing contracts.

 Integration & Longevity

Modular, Serviceable Architecture TW‑420A is built for longevity—major components are easily accessible and modular. Dust collectors and grinder units are integrated and detachable for cleaning or replacement.

Global Support & After-Sales Tai Wei offers field installation, commissioning, training, spare parts, and technicians for international clients. Spare components are readily available, ensuring minimal downtime during wear and tear.

Certifications & Quality Assurance With CE and ISO 9001 certifications, the machine meets international safety and manufacturing standards. As a recognized patent-holding enterprise and editor of national safety standards, Tai Wei supports superior design and reliability. 

Ideal Applications

• Footwear manufacturing: splitting upper leathers, skiving midsoles, trimming pointed toes.

• Leather goods: belts, wallets, bags—where precise thickness is essential.

• Garment & Upholstery: leather coats, jackets, sofa skins—where uniform splits are required for lamination or lining.

• Automotive interiors: trimming soft leathers for dashboards, door panels with strict thickness tolerances.

The TW‑420A Band Blade Skin Machine stands out as an advanced yet robust splitting solution tailored for industries that demand consistent, high-quality material management. Its digital precision, smart automation, durable construction, and global support network make it a wise investment for factories aiming to raise production standards while reducing waste and operational overhead. Whether in footwear, leather goods, or specialized material processing, the TW‑420A delivers performance, safety, and efficiency—predictably meeting tight tolerances and high throughput needs.If you’d like to explore optional upgrades (e.g., fully automatic feed, larger width models like 520 mm/620 mm), comparative positioning against other Camoga-style splitters, or discuss logistics/pricing for Bangladesh, feel free to ask!
