> **Executive summary**\n>\n> Loose, overlapping, or irregular coils cause catastrophic tangling during unrolling, reduce pallet utilization, and compromise product marketability. Engineered for continuous extrusion lines and high-speed off-line winding, our automatic pipe and hose coiling machine combines precision dual-axis servo traverse synchronization with closed-loop tension regulation. Every wrap is laid flush against the previous turn across all layers, delivering rigid, dimensionally repeatable, and strapping-ready coils from 16 mm up to 50 mm OD hose.\n<iframe width="940" height="535" src="https:\/\/www.youtube.com\/embed\/PX4AsWQsPk0" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen><\/iframe>\n\n---\n\n<h2 id="table-of-contents">Table of Contents<\/h2>\n\n<ul>\n<li><a href="#lay">What makes a good coil<\/a><\/li>\n<li><a href="#sequence">Coiling sequence<\/a><\/li>\n<li><a href="#data">Machine data<\/a><\/li>\n<li><a href="#pitch">Lay pitch and traverse<\/a><\/li>\n<li><a href="#output">Output formula<\/a><\/li>\n<li><a href="#tension">Tension and hose type<\/a><\/li>\n<li><a href="#selection-checklist">Selection checklist<\/a><\/li>\n<li><a href="#safety">Safety<\/a><\/li>\n<li><a href="#engineering-faq">Engineering FAQ<\/a><\/li>\n<li><a href="#next-step">Next step<\/a><\/li>\n<li><a href="#related-reading">Related reading<\/a><\/li>\n<li><a href="#sources">Sources<\/a><\/li>\n<\/ul>\n\n<h2 id="lay">What makes a good coil<\/h2>\n\nCoil integrity directly impacts logistics efficiency, shelf presentation, and downstream uncoiling behavior. Three critical mechanical factors dictate overall coil quality:\n\n*   **Precision Lay Pitch (Zero-Gap, Zero-Cross):** Every turn must position adjacent to the preceding wrap without structural overlap or axial voids. Overlapping causes localized wall crushing, while irregular gaps lead to upper-layer collapse during high-tension packaging.\n*   **Constant Dynamic Tension:** The winding torque must dynamically adjust as the coiling diameter builds from inside diameter (ID) to outside diameter (OD). Uniform tension prevents core crushing on the inner layers and loose, telescoping wraps on the outer perimeter.\n*   **Repeatable Boundary Dimensions:** Rigidly controlled ID, OD, and width ensure uniform pallet nesting patterns without perimeter overhang. Dimensionally stable coils withstand automated radial strapping and stretch-film wrapping without tilting or unravelling during transit.\n\n<h2 id="sequence">Coiling sequence<\/h2>\n\nThe dual-station turret system executes a synchronized, non-stop winding cycle:\n\n1.  **Leading End Clamping:** The pneumatic clamping jaw on the active coiling reel mechanically secures the hose leading end against the expanding mandrel.\n2.  **Synchronized Acceleration:** The main spindle rotates, pulling the hose through precision low-friction guide rollers while the upstream accumulator compensates for line speed differentials.\n3.  **Servo-Controlled Traverse:** A ball-screw driven traversing guide arm tracks the reel rotation via an electronic cam (E-CAM), advancing linearly across the coil face per spindle revolution.\n4.  **Flange Reversal and Layering:** As the guide reaches the adjustable flange limit, the servo executes a controlled reversal, building consecutive concentric layers uniformly.\n5.  **Length Target, Deceleration, and Shear:** Upon reaching the preset encoder length, the winder decelerates, the flying cutter severs the hose, and the trailing end is secured.\n6.  **Turret Indexing and Auto-Strapping:** The two-station carousel indexes 180°, transferring the full coil to the integrated PP\/PET strapping station while the empty reel immediately initiates the next cycle.\n\n<h2 id="data">Machine data<\/h2>\n\n| Technical Parameter | Standard Specification | High-Capacity Range | Engineering Remarks |\n| :--- | :--- | :--- | :--- |\n| **Coil Inner Diameter (ID)** | 350–550 mm | 200–600 mm | Mechanically adjustable or pneumatic expansion |\n| **Coil Outer Diameter (OD)** | 500–800 mm | Up to 1000 mm | Maximum OD constrained by outer reel sweep |\n| **Coil Width** | 150–300 mm | 100–450 mm | Adjustable via manual or motorized reel flanges |\n| **Coil Weight Capacity** | 5–35 kg | Up to 60 kg | Dynamic rating per individual reel cantilever |\n| **Coiling Line Speed** | 1–60 m\/min | Up to 80 m\/min | Synchronized with extrusion haul-off \/ puller |\n| **Operational Stations** | 2 (Turret Indexing) | 1 \/ 2 | Continuous changeover without line stoppage |\n| **Installed Drive Power** | 4.5 kW | 7.5 kW | Dual-axis AC servo + gearmotor configuration |\n| **Strapping Media** | 12–13 mm width | 0.6–0.75 mm thickness | Automatic heat-seal PP or tensioned PET banding |\n\n*Custom reel geometries and high-stiffness pipe configurations (e.g., HDPE microducts or heavy reinforced lay-flat hoses) are engineered upon application review.*\n\n<h2 id="pitch">Lay pitch and traverse<\/h2>\n\nAccurate layer tracking requires strict synchronization between the linear travel of the traversing guide and the rotational displacement of the winding spindle.\n\n**Traverse Linear Velocity Formula:**\n`v_traverse = Pitch × (N_spindle ÷ 60)`\n\nWhere:\n*   `v_traverse` = Traversing carriage linear speed (mm\/s)\n*   `N_spindle` = Instantaneous reel rotational speed (RPM)\n*   `Pitch` = Axial advance per turn (mm)\n\n**Lay Pitch Calculation:**\n`Pitch = OD_nominal × k_p`\n\n*   `OD_nominal` = Nominal hose outside diameter (mm)\n*   `k_p` = Packing correction factor (typically `1.02–1.05` to prevent sidewall friction and bridging)\n\n**Turns per Completed Layer:**\n`Turns_layer = Floor((W_coil - 2 × C_clearance) ÷ Pitch)`\n\n*   `W_coil` = Usable width between reel flanges (mm)\n*   `C_clearance` = End-flange turnaround clearance (typically `0.5 × OD_nominal`)\n\nIf the traversing pitch is programmed too tight (`k_p < 1.00`), the hose is forced upward into a premature secondary layer, destroying coil flatness. Conversely, excessive traverse spacing opens voids where subsequent layers settle unevenly, causing binding during off-spooling. The electronic gear ratio dynamically links traverse travel to high-resolution encoder pulses from the spindle drive.\n\n<h2 id="output">Output formula<\/h2>\n\nLine throughput is determined by extrusion linear output, coil package length, and winder changeover efficiency:\n\n**Net Winding Cycle Time:**\n`T_wind = L_coil ÷ v_line`\n\nWhere:\n*   `T_wind` = Active winding duration (min)\n*   `L_coil` = Total packaged hose length (m)\n*   `v_line` = Continuous extrusion or unwinding line speed (m\/min)\n\n**Total Coil Cycle Time (Dual-Station Turret):**\n`T_total = T_wind + T_index`\n\n*   `T_index` = Turret rotation, clamp, and cut changeover time (approx. `0.15–0.25 min`)\n\n**Example Calculation:**\nFor a `50 m` hose coil running at an extrusion speed of `25 m\/min`:\n`T_wind = 50 m ÷ 25 m\/min = 2.0 min`\nWith a dual-station turret system, the full cycle requires roughly `2.2 min` per completed unit, yielding approximately `27 coils\/hour`. Because strapping and pneumatic coil ejection occur concurrently at Station 2 during the active winding of Station 1, packaging cycle times do not create upstream extrusion bottlenecks.\n\n<h2 id="tension">Tension and hose type<\/h2>\n\nWinding tension must be configured to balance physical hoop stress against the structural integrity of the tube cross-section:\n\n*   **Soft PVC and Polyurethane Hose:** Flexible hoses are susceptible to longitudinal elongation and transverse necking under excessive pulling forces. A closed-loop pneumatic dancer arm maintains tension within a strict range (`5–15 N`), ensuring the material maintains its nominal dimensions without internal memory stress that induces post-packaging shrinkage.\n*   **Textile-Braided and Rubber Hose:** High axial tensile strength requires moderate winding force (`20–50 N`) to seat each turn tightly against the mandrel and eliminate barrel distortion.\n*   **Corrugated and Profile Tubing:** Thin-walled corrugated tubes crush easily when subjected to high radial containment forces. The coiler utilizes low-mass dancer assemblies with software-driven torque tapering, decreasing winding torque proportionally as coil diameter increases to prevent inner-layer collapse.\n\n<h2 id="selection-checklist">Selection checklist<\/h2>\n\nWhen engineering an automatic hose coiling and strapping integration, specify the following mechanical and production parameters:\n\n1.  **Tube Specifications:** Hose nominal OD, minimum\/maximum outer tolerance, wall thickness, Poisson's ratio, and material type (e.g., PVC, PE, PU, EPDM, Silicone).\n2.  **Target Package Dimensions:** Coil inner core diameter (mandrel size), maximum outer diameter, traverse width, and total weight per coil.\n3.  **Throughput Profile:** Upstream continuous extrusion speed (`m\/min`), target coils per hour, and cut-length tolerances.\n4.  **Operational Integration:** Continuous in-line extrusion (requiring upstream dancer\/accumulator coordination) or standalone off-line rewinding from master bobbins.\n5.  **Finishing Options:** Number of radial strapping bands (2, 3, or 4 straps), intermediate stretch-film overwrapping, or automatic shrink bagging.\n6.  **Downstream Logistics:** Integrated weight verification, automated barcoding\/labeling, and reject discharge mechanisms.\n\n<h2 id="safety">Safety<\/h2>\n\nThe system incorporates robust safety architectures compliant with international industrial standards:\n\n*   **Machinery Directive Harmonization:** Engineered in full compliance with **EN ISO 12100:2010** for general machine risk mitigation and **EN 415-10** for packaging and winding machine functional safety.\n*   **Control Reliability:** Electrical equipment is designed to **EN 60204-1**, featuring an **EN ISO 13849-1 (Category 3, Performance Level d)** dual-channel safety circuit.\n*   **Physical Perimeter Guarding:** High-visibility interlocked perimeter fencing prevents operator intervention inside the turret sweep zone during rotation.\n*   **Emergency Braking and LOTO:** Pneumatic failsafe friction brakes bring the high-inertia rotating reel to a dead stop within `< 1.5 seconds` upon emergency stop depression or light curtain breach. Fully lockable Lockout\/Tagout (LOTO) energy isolation points are standard for all mechanical, electrical, and pneumatic supplies.\n\n<h2 id="engineering-faq">Engineering FAQ<\/h2>\n\n**Q: How does the system prevent hose wall flattening during high-speed coiling?**\nA: Wall preservation is managed through a closed-loop pneumatic dancer assembly coupled with vector-controlled servo drives. By continuously modulating spindle torque based on real-time dancer position feedback, winding tension is held constant within `±2%`, preventing excessive radial hoop compression on lower layers.\n\n**Q: Can this machine synchronize directly with an uninterrupted extrusion line?**\nA: Yes. For continuous in-line production, the coiler interfaces directly with the extrusion haul-off via analog `0–10 V` or fieldbus communication (Profinet\/EtherNet\/IP). A vertical accumulator tower buffers upstream material for 15–20 seconds during the automated flying shear and turret rotation sequence.\n\n**Q: How long does reel tooling changeover take for different coil dimensions?**\nA: Standard adjustments—such as varying the inner core diameter or resetting the flange width—utilize quick-release clamping collars and digital position indicators, taking less than 10 minutes. For automated recipes, servo traverse limits and tension curves are recalled instantly via the HMI touchscreen.\n\n**Q: What strapping materials are compatible with the integrated binding head?**\nA: The standard strapping module accommodates standard 12 mm or 13 mm polypropylene (PP) strapping, joining the ends using a micro-controlled thermal friction weld. Polyester (PET) banding setups are available for heavy-duty, high-rebound industrial hose lines.\n\n<h2 id="next-step">Next step<\/h2>\n\n1.  **Submit Specifications:** Forward your tube dimensions (OD\/ID), material data sheets, coil targets (ID\/OD\/Width), and production speeds to **info@fhopepack.com**.\n2.  **Engineering Review:** Our design team calculates winding inertia, tension ranges, and layout drawings tailored to your plant footprint.\n3.  **Comprehensive Quotation:** Receive a fully detailed commercial and technical proposal—including cycle-time simulations and layout drawings—within 24 hours.\n\n<h2 id="related-reading">Related reading<\/h2>\n\n*   [Hose coiling and strapping machine (product)](https:\/\/www.fhopepack.com\/Hose-packaging-machine\/Hose-coiling-and-strapping-machine.html)\n*   [Automatic hose coiling machine FCL-600 (product)](https:\/\/www.fhopepack.com\/Vertical-Coiling-Machine\/Automatic-hose-coiling--machine-FCL-600.html)\n*   [Automatic coiler for corrugated hose and plastic pipe](https:\/\/www.fhopepack.com\/videos\/automatic-coiler-for-corrugated-hose-plastic-pipe\/)\n*   [Automatic hose coiler with strapping machine](https:\/\/www.fhopepack.com\/videos\/automatic-hose-coiler-with-strapping-machine\/)\n\n<h2 id="sources">Sources<\/h2>\n\n*   FHOPE Packaging Machinery: Engineering Specifications for FCL Series Automatic Hose Winders.\n*   EN ISO 12100:2010 – Safety of machinery – General principles for design – Risk assessment and risk reduction.\n*   EN 415-10 – Safety of packaging machines – General requirements.\n*   EN 60204-1:2018 – Safety of machinery – Electrical equipment of machines – Part 1: General requirements.\n\n<p><strong>Last reviewed:<\/strong> 2026-10-20<\/p><\/code><\/pre>","protected":false},"excerpt":{"rendered":"
