Coil Wrapper with Logo Taping: Process, FPW-300 Specs, and Material Calculation

Executive summary

A coil that arrives with an uneven wrap rusts at the gaps, and a coil that arrives without its mark is hard to trace on the customer’s floor. A coil wrapper with logo tape passes printed paper or film tape through the coil eye, so every coil leaves sealed and branded in one cycle. This page covers how the wrapper works, the FPW-300 data, what to watch with printed tape, and how to estimate tape length per coil.

In operation, the coil is rolled onto the carrier rollers and centred against the ring. The ring passes printed paper or film tape through the coil eye while the carrier rollers rotate the coil, so the print repeats around the coil section. The control panel carries the mode selector and the error indication, and the wrapped coil is rolled out sealed and branded in a single cycle.

Why coils need a logo wrap

Plain film keeps dust and water out but says nothing about the product. Once a coil leaves the primary slitting or drawing line, field handling introduces significant identity risks:

  • End-to-end traceability: A printed logo tape repeats the manufacturer brand, heat number, and steel grade over the entire outer circumference and through the eye. When a master pack or bundle is opened at a fabrication plant, a single cut coil can still be instantly identified without external tags.
  • Immediate tamper evidence: Secondary strapping or transparent stretch films can be cut and retied without immediate notice. A printed wrap profile cannot be patched with generic clear material without visual mismatch, alerting downstream receiving teams to transit inspection.
  • Specification compliance: High-tensile PC strand, high-carbon spring wire, and precision cold-rolled strip coils routinely encounter strict client packaging directives that demand continuous brand verification to prevent stock mix-ups in warehouse racks.

How the wrapper works

The orbital through-eye packaging sequence relies on two synchronized mechanical drives:

  1. Load and align: The coil is rolled in onto the carrier rollers. A mainframe height adjustment centres the ring on the coil.
  2. Orbital wrapping: The shuttle mounted on the rotating ring carries the tape roll through the open coil eye. While the ring revolves orbitally, the motorized carrier rollers rotate the coil along its horizontal axis.
  3. Pitch and overlap synchronization: Ring speed against roller speed sets the overlap ratio (10%–90%), so the logo repeats evenly.
  4. Cut and discharge: The tape is cut and the coil is rolled out.

Manual button mode and one-key automatic running are both available, and an E-stop and error light sit on the panel.

FPW-300 data

The table below outlines the core mechanical envelope for the FPW-300 model series:

Item FHOPE FPW-300 coil wrapper
Coil ID 508–610 mm
Coil OD 600–1,200 mm
Coil width 100–300 mm
Coil weight 20–1,000 kg
Packing material PVC, LLDPE, PE, paper, HDPE
Material roll ID 50 mm, OD 100–450 mm, width 100–150 mm
Overlap 10%–90%
Power 1.5 kW, 380 V 50 Hz 3 phase
Air supply 4–6 bar

The FPS-300 steel strip version is the same machine; sizes are adjusted to your coil, and coils outside these ranges are confirmed at quote. In continuous configurations the platform supports up to 60 coils per hour [manufacturer rating]. The machine is CE compliant, manufactured under ISO 9001 quality management, and carries a 2-year warranty [manufacturer rating].

Operating with branded media introduces strict friction and visual alignment considerations:

  • Repeat length: Choose a print repeat shorter than the visible tape width per turn, so each lap shows the full logo.
  • Overlap: At 50% overlap half of each lap is covered; set it so the print stays readable.
  • Tension: Paper tape needs lower tension than film, or it tears at the coil edge.
  • Direction: Print reads along the tape, so it runs around the coil section.

Tape length per coil

Tape consumption depends on coil dimensions, tape width, and the programmed overlap ratio:

Tape length ≈ ring turns × perimeter of the coil section Ring turns = π × mean diameter ÷ (tape width × (1 − overlap))

For an illustrative coil running in production:

  • Outer Diameter (OD) = 1,000 mm
  • Inner Diameter (ID) = 600 mm
  • Coil Width = 200 mm
  • Tape Width = 100 mm
  • Overlap Ratio = 50% (0.50)

Step 1: Calculate Mean Diameter and Circumference

  • Mean Diameter = (OD + ID) ÷ 2 = (1,000 + 600) ÷ 2 = 800 mm
  • Circumference = π × 800 mm ≈ 2,512 mm

Step 2: Calculate Ring Revolutions

  • Effective Advance Pitch = Tape Width × (1 − Overlap) = 100 mm × (1 − 0.50) = 50 mm
  • Ring Turns = 2,512 mm ÷ 50 mm ≈ 51 turns (rounded to nearest integer)

Step 3: Calculate Coil Cross-Section Perimeter

  • Radial Wall Thickness = (OD − ID) ÷ 2 = (1,000 − 600) ÷ 2 = 200 mm
  • Section Perimeter ≈ 2 × (Width + Radial Wall) = 2 × (200 + 200) = 800 mm (0.8 m)

Step 4: Calculate Total Length

  • Tape Consumption ≈ 51 turns × 0.8 m = 41 m per coil (example only).

Selection checklist

Confirm the following line parameters before finalizing equipment engineering:

  1. Coil physical envelope: minimum and maximum ID, OD, axial width, and maximum unit weight?
  2. Production capacity: required coils per shift or line cycle rate (seconds per coil)?
  3. Material strategy: single-layer printed logo tape, or primary barrier film (plain stretch/VCI) sealed first with logo tape applied on the outer pass?
  4. Tape substrate and print artwork: reinforced industrial paper or extruded film, core ID, roll OD, and graphic repeat length?
  5. Loading by rolling, crane or forklift trolley?
  6. Weighing and label printing needed?

Safety

Every wrapper assembly is built in accordance with mandatory industrial safety regulations:

  • Risk Assessment: Certified under EN ISO 12100:2010 for general machine risk mitigation.
  • Packaging Safeguards: Built to EN 415-10 packaging machine safety requirements. The ring is fenced.
  • Electrical Architecture: Configured to EN 60204-1 standards. The E-stop and error light sit on the panel.

Engineering FAQ

Q: Can the FPW-300 apply clear protective stretch film and paper logo tape in a single operation? A: Yes, in two passes or with a second head, set per project. Equipment can be customized to your application requirements [manufacturer rating].

Q: Why does paper logo tape tear at coil shoulders, and how is it prevented? A: Not at the right tension; it is set lower than for film. Edge protectors can be placed on sharp coil edges before wrapping.

Q: What is the maximum coil mass that an operator can load manually? A: Light coils can be rolled in by hand; heavier coils use a loading trolley.

Q: Can we capture real-time coil weight and apply a printed dispatch barcode label automatically? A: Yes, a weighing station and label printer can be added after the wrapper.
