Optical Fiber Take-Up Winder Clamp & Cutter Assembly (Auto-Bobbin Changeover Unit)

The Optical Fiber Take-Up Winder Clamp & Cutter Assembly is a mission-critical consumable mechanism installed on high-speed optical fiber drawing towers and dual-bobbin take-up winders. During continuous high-speed drawing, it performs two essential synchronized functions: firmly trapping/clamping the fiber tail during winding, and cleanly severing the optical fiber upon bobbin full-load changeover without interrupting tower production.

Engineered to eliminate false cuts, fiber slip, and mechanical jamming, our assembly combines a self-lubricating precision brass base, heavy-duty die spring actuation, and wear-resistant cutting blades for millions of smooth switching cycles.

Key Features & Engineering Advantages

• Precision-Guided Clamping & Shearing: Symmetrical blade geometry delivers clean, burr-free fiber cleavage and reliable clamping pressure, preventing fiber micro-cracks and flying tails.
• Wear-Resistant Brass/Bronze Housing: High-grade brass base structure provides exceptional wear resistance, smooth sliding guidance, and non-sparking safety during rapid pneumatic/mechanical actuation.
• High-Endurance Hardened Blades: Cutting/clamping leaves are made from high-toughness stainless steel / tool steel alloys, ensuring prolonged sharpness and fatigue resistance under thousands of high-speed changeovers.
• Pre-Loaded Die Spring Actuator: Integrated industrial-grade compression spring provides instantaneous rebound force, ensuring repeatable clamping tension and rapid reset timing.
• Direct OEM Drop-In Fit: Compatible with leading international and domestic optical fiber take-up winders (Nextrom, Rosendahl, Maillefer, and standard Chinese automated spoolers).

Custom CAD & Sample-Based Manufacturing (OEM / ODM)

Because different generations of drawing tower winders utilize customized blade angles, mounting bore spacings, or pneumatic stroke lengths, we provide full custom CNC turn-mill machining services:

• 2D/3D CAD Machining: Send us your technical drawings (STEP, IGES, DXF, DWG, PDF) for direct machining.
• Physical Sample Duplication / Reverse Engineering: Send us your worn or legacy clamp & cutter block—our engineering team will inspect critical dimensions and supply 100% functional replacements.
• Material Customization: Alternative body materials (Hard-Anodized Aluminum, Titanium, 316L Stainless Steel) or specialized tungsten-carbide-coated blades available upon request.
