Steel Coil Strapping and Wrapping Line: The Four Modules

Executive summary A steel coil packaging line is built from modular stations, so each plant picks the stages its coils and dispatch need. The four modules in this line are an orbital wrapping station on a powered roller conveyor, a gantry handling carriage with a scissor-lift table, a press and strapping unit, and a vertical strapping station that secures the wrapped coil to a wooden pallet. Strap length per coil-to-pallet band follows from coil OD, coil width and pallet height; we set both per project.

What the machine does

The line runs four modules in sequence and needs no crane transfer between them.

First, the coil rolls on the powered conveyor into the wrapping zone. A rotating ring feeds film through the coil eye and around the outer wrap while the rollers index the coil, giving a cover against moisture and surface damage.

Next, a gantry carriage grips the coil, and a scissor-lift table under the roller deck sets the transfer height.

Then the coil moves to the press and strapping station: a platen presses the package to stabilize the outer wraps, and the strapping head feeds, tensions, seals and cuts bands around the coil or through the eye.

Last, the coil is placed on a wooden pallet, where a vertical strapping head with strap guides runs bands over the coil and through the pallet, locking the two together for transport.

The four modules

The modules link by motorized roller conveyor:

Module What it does
Wrapping station Wraps the coil on the roller conveyor
Gantry handling Picks and moves the coil; scissor lift sets the height
Press and strapping Presses the coil and bands it
Coil-to-pallet strapping Bands the wrapped coil to its wooden pallet

Because the modules link by roller conveyor, a plant can start with two stations and add the others as throughput grows. For a standalone banding cell, see our automatic steel coil strapping machine.

For high-volume slitting lines, the same architecture also pairs upstream with 2- or 4-arm turnstiles (up to 60 t per coil, arms up to 2000 mm) and hydraulic 90° down-enders, and downstream with gantry-based stacking cells [manufacturer rating].

Strap per coil-to-pallet band: a quick estimate

A band that ties a coil to its pallet runs over the coil and under the pallet deck. The rectangular path below is an upper-bound estimate; the real band follows the coil curve and is a little shorter. Illustrative example for a coil lying eye horizontal:

Item Value
Coil width (illustrative) 1,000 mm
Coil OD (illustrative) 1,500 mm
Pallet height (illustrative) 150 mm
Band length, 2 × (1,000 + 1,500 + 150) 5,300 mm
Bands per pallet (illustrative) 2
Strap per pallet, 2 × 5.3 m 10.6 m

Add the seal overlap to each band when you order strap.

Choosing modules

Need Module
Dust and moisture cover Wrapping station
No crane between stations Gantry handling
Radial or circumferential bands on the coil Press and strapping
Coils shipped on pallets Coil-to-pallet strapping

We match the module list to your coil flow and dispatch method, then lay out the conveyor.

Controls and safety

The gantry carriage, scissor lift and strapping heads move automatically over the conveyors. Keep people out of the module zones while the line runs, and enter only with the station stopped and locked out.

The standards that apply depend on the destination market. For CE markets, ISO 12100 sets the risk-assessment method and EN 415-10 covers packaging machines. Line control uses safety PLCs (Pilz, Siemens or Allen-Bradley) with E-stop circuits, interlocks and optional light curtains per ISO 13849 [manufacturer rating].

Selection checklist for a steel coil strapping and wrapping line

  • Coil OD, ID, width and weight range.
  • Coils per hour.
  • Wrapping material.
  • Straps per coil and per pallet.
  • Pallet size and height.
  • Building space and crane access.

Engineering FAQ

Q: How are the modules connected? A: By roller conveyors, so a plant can start with some modules and add the rest later.

Q: How long is a coil-to-pallet band? A: About 5,300 mm for a 1,000 mm wide, 1,500 mm OD coil on a 150 mm pallet in our example.

Q: Can I start with fewer modules? A: Yes. The modules link by conveyor, so others can be added later.

Q: What is the scissor lift for? A: It sets the coil height under the gantry.

Q: Is strap overlap included in the example? A: No. Add the seal overlap to each band.

Next step

We plan your coil strapping and wrapping line in three steps:

  1. Submit your layout drawing with coil sizes, pallets and output to info@fhopepack.com.
  2. Receive a proposal within 48 hours, with the module list and layout.
  3. Book a site survey to check the building and crane access.
