Micro Fiber Line

We offer both monofilament and multifilament filament lines—true micro filament lines— engineered to meet diverse production goals in textiles, advanced materials, and medical devices. These systems deliver high-performance, micro-scale fiber spinning with the consistency required for fine filaments, complex multi-strand fibers, or specialized fiber tows used in composite lay-ups and biomedical implants. Whether you need tight diameter control or custom draw profiles, the line’s melt-pump and precision cross-head ensure uniform throughput and repeatable results on every run.

One of the core elements of every line is the take-up winder (rewinder), which governs the efficient transfer of extrudates onto a spool. Designed to handle both round strands and ribbon-shaped extrudates, this winder provides the versatility needed for a wide range of materials and geometries, from simple filaments to flat tape—effectively covering everything from suture threads to micro tape for electronic laminates. The result is a single piece of equipment that adapts seamlessly to evolving R&D or pilot-scale requirements.

The winder incorporates an adjustable tensile-force control loop between the take-off roller and spool, enabling operators to fine-tune line tension for perfect uniform winding. By preventing slack, telescoping, or over-tensioning, the system eliminates common winding defects such as neck-in, yarn fuzz, or broken ends, thereby preserving filament properties and safeguarding downstream textile or weaving steps. Precise pull-force management is especially critical when running fragile melt-spun fibers, hygroscopic polymers, or elastomeric blends that are sensitive to stress variations.

For intuitive operation, speed and tension are set via an integrated potentiometer and frequency inverter, simplifying line startup and recipe changes. A digital interface allows direct connection to higher-level PLC or MES networks, providing real-time data exchange on draw ratio, spool weight, and line speed. This connectivity streamlines recipe management, centralizes quality records, and supports fully automated production cells where closed-loop feedback is required to maintain tight tolerances.

Despite its robust performance, the winder’s compact footprint fits easily into space-restricted labs or pilot halls without sacrificing reliability. Tool-free access to rollers and guides accelerates changeovers, while modular build options—such as heated godet rollers or air-shaft spools—extend the platform’s capability to new polymers and process chemistries. By delivering stable tension, micro-scale winding, and seamless line integration, the equipment boosts throughput and minimizes scrap, directly improving cost-per-run metrics.

In summary, our rewinder for monofilament and multifilament filament lines offers a reliable, flexible, and efficient solution for micro-scale fiber production. Adjustable pull force, intuitive controls, and full system compatibility make it indispensable for maintaining throughput and quality—whether you operate a small R&D line or a fully automated pilot plant. By guaranteeing precision fiber spinning and trouble-free winding, this filament-line winder underpins successful product development and scalable manufacturing alike.
