In high-voltage, fire-resistant, and specialty cable production, accurate tape application is critical for shielding, mechanical protection, and fire performance. The RLB High Speed Eccentric Taping Machine delivers industry-leading tangential (eccentric) taping technology for both non-metallic tapes (copper/aluminum foil, paper, mylar, textile, PE) and steel tape armoring. Its independent servo-driven design, constant-tension control, and high-speed capability make it the preferred solution for inline or standalone operation in modern cable lines.
Available in two specialized configurations — Cu/Al Tape version for lightweight non-metallic tapes and Steel Tape version for heavy-duty armoring — the RLB eccentric taping machine ensures uniform overlap, zero slippage, and consistent tension from full to empty pad, eliminating common defects such as wrinkles, gaps, or tape breakage.
Core Technology & Performance Advantages
- Eccentric Tangential Design: 2 pads per head with external bobbin placement (especially advantageous for steel tape) provides smooth, high-speed wrapping with minimal vibration.
- Independent AC Servo Drive: Precise speed synchronization, programmable overlap rate, and automatic tension compensation for perfect taping even at maximum RPM.
- MMI + PLC Intelligent Control: Touch-screen preset of taping pitch, direction, tension, and speed — with real-time monitoring and automatic stop on tape end or fault.
- High-Speed Operation: Up to 700 RPM (non-metallic) and 350 RPM (steel tape) for exceptional productivity.
- Easy Integration: Can be added to existing extrusion, stranding, or armoring lines; complete standalone steel tape armoring lines include pay-off, tractor, and take-up.
The result is superior cable quality, reduced scrap, and significantly lower labor requirements compared to traditional concentric taping systems.
