Product Overview of Yarn Rack for Fiberglass Direct Roving

The Yarn Rack for Fiberglass Direct Roving (also recognized globally as a heavy-duty FRP tension creel or continuous roving spooler framework) is an essential upstream auxiliary component engineered by Henan Zhongsheng for automated composite pultrusion manufacturing lines. Its primary industrial function is to provide organized, high-density storage and friction-free unwinding for continuous glass fiber or carbon fiber direct roving balls, ensuring uniform strand feeding velocity and zero structural fiber twisting prior to the resin impregnation phase.

Advanced Structural Engineering & Welding Integrity

To eliminate physical vibration and withstand the continuous pulling traction exerted by heavy-duty gantry machinery, our roving frame integrates robust mechanical construction:

• Industrial Metal Frame: Fabricated utilizing premium 5# heavy angle iron coupled with 50X30X2.5mm heavy-wall square steel tubes, fully assembly-welded to prevent structural deflection over multi-year non-stop manufacturing cycles.
• Precision Eyelet Processing: The angle iron facades undergo dedicated automated machining to create a comprehensive series of micro-smooth yarn guiding holes. Each direct roving strand is fed through its own dedicated channel, minimizing overlapping friction.
• Modular Scaling Expansion: The standard factory layout constitutes one integrated structural creel frame holding up to 210 balls. Depending on your customized profile thickness or multi-cavity pultrusion die layouts, multiple modular yarn frames can be interconnected inline.

Technical Parameters and Dimensional Specifications

Below are the standardized structural dimensions and payload capacities for the Zhongsheng industrial roving unwinding matrix:

Value Proposition for Factory Production Optimization

• Elimination of Fiber Fuzzing & Degradation: Dedicated eyelet isolation prevents continuous rovings from scraping against adjacent strands, suppressing fiber blooming and securing the mechanical shear strength of final profiles.
• Rapid Package Changeover Uptime: The spacious 5-layer open matrix layout allows plant operators to swap spent φ300mm yarn packages and knot trailing filaments instantly, slashing production line downtime to near zero.
• Constant Tension Delivery: Smooth drawing paths prevent sudden strand snapping inside the heated mold cavity, reducing component failure rates on your continuous pultrusion machinery.
