Executive summary Our automatic inline coil wrapper receives hose coils, corrugated pipe coils, and cable reels directly from powered roller conveyors to perform through-the-eye protective stretch wrapping. The standalone wrapping unit completes a cycle in 20–40 s per coil, while a complete coiling, strapping, and palletizing line maintains a steady throughput of approximately 30 coils per hour. Coil inner diameter (ID/eye), outer diameter (OD), package width, and extrusion line speed determine the mechanical ring frame sizing and layout configuration.

How the inline wrapper works

Our automatic coil wrapper is engineered directly over an inline powered roller conveyor system. When a coil or reel transfers to the packaging station, it lies in a flat horizontal orientation (eye-to-sky axis). The system centers and secures the coil pneumatically without manual intervention:

Centering and clamping: Integrated side-guide rollers align the coil along the machine centerline. A pneumatic top press roller assembly descends to clamp the workpiece securely against twin driven base rollers, preventing coil unraveling, telescoping, or shifting during rotation.
Orbital eye penetration: A balanced, high-tensile cast-aluminum rotating ring carries the pre-stretch film dispenser shuttle. The ring rotates vertically through the open central eye of the coil while the driven base rollers slowly turn the coil about its central vertical axis.
Synchronized surface coverage: Variable frequency drives (VFD) independently govern ring orbital velocity and base roller rotation speed. This electromechanical synchronization guarantees precise film overlap across the inner core, outer circumference, and sidewall faces.
Automated cycle cutoff: An integrated pneumatic mechanical hand clamps, cuts, and wipes the film tail against the coil body at the end of the preset wrapping cycle.

Because coils arrive and exit via motorized conveyors, operators are spared from heavy lifting between extrusion, coiling, strapping, and orbital wrapping.

Automatic hose coil packing line with coil wrapper on roller conveyors — **Hose coil packing line.** Continuous coiling, through-the-eye orbital wrapping, and downstream conveying in an integrated automated workflow.

Eye and coil windows

The orbital ring and its film carriage must pass directly through the central eye bore of the coil. Consequently, the minimum coil inner diameter (ID) determines machine selection. For spools and reels, this dimension corresponds to the center core bore clearance:

Effective Clear Bore ≥ Film Dispenser Shuttle Width + Structural Radial Clearance (minimum 50 mm)

Parameter	Packaging Line Standard	Model FPH-300N	Model FPH-400W
Coil ID (Eye core)	350–400 mm	300–700 mm	300–1,250 mm
Coil OD	500–650 mm	500–1,000 mm	700–1,500 mm
Coil width / height	150–250 mm	100–300 mm	150–400 mm
Coil weight capacity	8–50 kg (up to 300 kg custom)	10–100 kg	10–100 kg
Wrapping cycle time	20–40 s (standalone)	23–35 s	30–55 s
Maximum ring speed	Determined by coil size	120 r/min	100 r/min

Selection Examples:

A standard flexible PVC or garden hose coil with 400 mm ID, 600 mm OD, and 200 mm width runs comfortably on both the standard inline cell and the compact FPH-300N.
A heavy-duty PEX coil, drip irrigation coil, or large industrial wire reel with a 900 mm inner bore, 1,300 mm OD, and 350 mm width requires the enlarged orbital clearance of the FPH-400W.

Seconds per coil versus extrusion rate

In an automated extrusion line, the through-the-eye wrapper is rarely the production bottleneck. System capacity is calculated by pairing the orbital wrapping cycle time against the upstream extruder cycle output:

Standalone wrapper throughput: Operating at 20–40 s per complete wrapping cycle, a standalone wrapper has a physical processing ceiling of 90–180 coils per hour.
Integrated complete line capacity: Upstream automated coiling, cutting, 180° indexing, strapping, wrapping, and palletizing combined achieve a stable takt time of approximately 30 coils per hour (120 s per finished unit).
Extrusion line output calculation (illustrative): An extruder producing 100 m continuous pipe coils at a line hauling speed of 20 m/min outputs one coil every 5 minutes:

Cycle time = 100 m ÷ 20 m/min = 5 min per coil (12 coils/h)

Under these parameters, one inline wrapper readily processes the output of the extrusion line with substantial idle safety buffer. In multi-extruder plants, a centralized transfer conveyor allows a single inline wrapper to service two or three parallel extrusion lines simultaneously.

Line modules

Our turnkey packaging systems incorporate modular stations that integrate directly downstream from extrusion haul-off units:

Module	Primary Engineering Function
Automatic hose and pipe coiler	Automatically captures continuous extruded PVC, CPVC, PEX, or PE pipe, regulates line tension, cuts to exact preset length, and winds structured coils.
Precision tensioning dancer	Eliminates line surging, protects wall thickness tolerances, and ensures uniform coiling density.
Automated layering arm	Traverses synchronously with spindle rotation to arrange neat, multi-layer rows without tangling.
180° coil tilting / indexer	Discharges completed coils from the horizontal spindle and pivots them 180° onto the flat roller bed for direct in-line transfer.
Automatic through-the-eye wrapper	Encapsulates the annular coil body through the center eye with protective stretch film or protective tape against moisture, UV, and transit abrasion.

Film and material

The orbital ring system accommodates diverse industrial flexible packaging substrates depending on barrier and transit requirements:

Item	Technical Specification
Wrapping materials	LLDPE cast stretch film, HDPE film, PVC stretch wrap, or reinforced woven PP tape
Overlap ratio	10% to 90% continuous adjustability via touch-screen HMI settings
FPH-300N film roll dimensions	Width: 90–100 mm; Roll OD: 100–180 mm; Core ID: 50 mm (2 in)

Selection checklist for an inline coil wrapper

Review these project criteria before finalizing machine sizing:

Coil geometry: Minimum and maximum Inner Diameter (eye bore), Outer Diameter, and axial Height/Width.
Unit mass: Maximum weight per single coil or loaded reel (standard up to 100 kg; heavy-duty options to 300+ kg).
Line velocity: Extrusion hauling speed (m/min), coil cut length (m), and target production rate (coils/hour).
Consumable selection: Standard LLDPE stretch film, VCI anti-corrosion wrap, or high-tensile woven tape.
Automation integration: Standalone workstation versus inline connectivity with upstream auto-coiler, strapping unit, and robotic palletizer.
Factory envelope: Infeed/outfeed conveyor top-of-roller height (TOR), material flow direction, and floor footprint limitations.

Engineering FAQ

Q: Can the exact same orbital machine wrap both unsupported hose coils and flanged reels? A: Yes. As long as the flanged reel features a through-core bore of at least 300 mm (to permit clearance for the orbital ring and film carriage) and its total flange width falls within the machine clamping stroke, both product types run on the same conveyor line.

Q: What is the real-world cycle time per coil? A: Standalone wrapper cycle time ranges between 20 and 40 seconds depending on coil circumference and the specified overlap percentage. When integrated into a fully synchronized extrusion packing line with strapping and indexing stations, net throughput stabilizes at roughly 30 coils per hour (120 s takt time).

Q: Will the inline wrapper create a bottleneck on high-speed extrusion lines? A: In standard configurations, no. For instance, a line producing 100 m coils at 20 m/min yields one coil every 5 minutes (12 coils/h). A 20–40 s wrapper cycle easily manages this rate with surplus handling capacity.

Q: What is the largest package dimension supported by the standard FPH series? A: The standard FPH-400W model accommodates coil/reel inner bores from 300 mm up to 1,250 mm, outer diameters up to 1,500 mm, and package widths up to 400 mm, with total coil weight up to 100 kg. Larger coils require our heavy-duty engineering series.

Q: What compressed air specification is required on site? A: The pneumatic centering guides, top clamp cylinder, and automatic film cutoff hand require a clean, dry compressed air supply at 0.6–0.8 MPa (6–8 bar), filtered to 5 µm.
