Steel Strip Coil Packing Machine: Inline Eye-Through Wrapping

Executive summary An inline steel strip coil packing machine wraps each coil on a roller conveyor, so coils arrive bare and leave wrapped without a crane lift. In our clip a rusty strip coil enters, the wrapping head comes down at about 10 to 12 s and the coil leaves in a white cover by about 28 s. For this class our FPS-400 takes coils of 508 or 610 mm ID, 800 to 1,400 mm OD and 100 to 2,000 kg.

What the clip shows, in order

The machine has a blue steel frame with a vertical column and a wrapping head over a roller conveyor. Yellow side guides run along the conveyor, and a white control box with buttons stands on the right. A red and green lamp column sits on the left-hand post.

  1. 0 to about 8 s. A dark brown strip coil with rust on its surface lies flat on the rollers under the head. The head is at rest, and wrapped white coils stand in the background.
  2. About 10 to 12 s. The conveyor moves the coil under the head and the head starts down toward the coil.
  3. About 14 to 20 s. The head is down at the coil, and a white cover builds up over the outer turns. A worker in a white hard hat stands at the control box and watches.
  4. About 22 to 28 s. The head lifts, and the coil, now fully covered in white, moves on along the conveyor. The green lamp is lit.
  5. About 30 to 38 s. With the machine on standby, the worker places a coil on the conveyor by hand.
  6. About 40 to 46 s. The worker steps back to the right. A dark coil moves into the centre and the head comes down again.
  7. About 48 to 56 s. The head works on the coil while the worker watches, a second white coil waits on the right, and at about 56 s the head is back up.

Cycle time on the clip

Step on the clip Time window Duration
Coil at rest under the head 0 to about 8 s about 8 s
Coil indexed in, head comes down about 10 to 12 s about 2 s
Wrapping with the head down about 14 to 20 s about 6 s
Head up, wrapped coil leaves about 22 to 28 s about 6 s
Head down, first and next coil about 10 to 12 s, then about 40 to 46 s about 28 to 34 s apart

The times come from frames 2 s apart. From one head-down to the next is about 28 to 34 s, and that includes the manual load at about 30 to 38 s. With a powered infeed, that load step moves off the critical path.

Why wrap strip coils inline

Strip coils come off the slitter in numbers, and each one needs a cover before it rusts, picks up dirt or marks its edges in handling. Wrapping them on the same conveyor that carries them avoids a crane lift for every coil. It also keeps the coil flat, so the edges are not knocked as the coil is turned.

On the clip the bare coil already shows rust, which is the case for a cover. A film or paper wrap over the whole section closes the coil against moisture and dust during storage and transport.

FPS-400 specifications

The FPS-400 is our steel coil packing machine for this coil range. The machine in the clip is the same eye-through wrapping class, and we confirm the coil size before we propose it.

FPS-400 steel coil packing machine Specification
Coil inner diameter 508 or 610 mm
Coil outer diameter 800 to 1,400 mm
Coil width 100 to 400 mm
Coil weight 100 to 2,000 kg
Packing material PVC, LLDPE, PE, paper or HDPE
Material roll 50 mm core, 100 to 450 mm OD, 100 to 150 mm wide
Overlap rate 10% to 90%
Power 4.0 kW, 380 V, 50 Hz, 3 phase
Air supply 5 to 7 kgf/cm²

Takt check

For an illustrative target of 60 coils per hour, the takt is 3,600 ÷ 60 = 60 s per coil. The clip runs at about 28 to 34 s from one head-down to the next, so that pace sits well inside a 60 s takt.

At higher overlap the wrap takes longer, so we check the wrap time at your overlap and coil width in the proposal. When the slitter output is higher still, we add a powered infeed and a buffer so the wrapper never waits for a manual load.

Selection checklist for a steel strip coil packing machine

  • Coil ID, OD, width and weight, against the FPS-400 window in the table.
  • Wrapping material and overlap for the storage and transport time.
  • Output target per hour, matched to the slitter.
  • Infeed and outfeed: manual, powered conveyor or buffer.
  • Downstream steps: strapping, labelling, stacking on pallets.

Controls and safety

On the clip the worker watches from the control box while the head is down, and loads a coil by hand only while the machine is on standby. We build our equivalent design around that rule. A hand at the head or the conveyor while the head can move is the move to design out.

Stop, isolate and lock out the machine before anyone clears a material break, changes a material roll or works under the head. The lamp column shows the running state at a glance. On our equivalent design, guarding keeps hands away from the head and the rollers during the wrap.

The standards that apply depend on the destination market. For CE markets, ISO 12100 sets the risk-assessment method and EN 415-10 covers general requirements for packaging machines, which fixes guarding and the stop arrangement.

Engineering FAQ

Q: How fast does the machine in the clip wrap a strip coil? A: The head is down for about 6 s on the first coil, and one head-down follows the next about 28 to 34 s apart, including a manual load.

Q: Which coils fit the FPS-400? A: Coils of 508 or 610 mm ID, 800 to 1,400 mm OD, 100 to 400 mm width and 100 to 2,000 kg.

Q: Which wrapping materials can be used? A: PVC, LLDPE, PE, paper or HDPE, with an overlap rate of 10% to 90%.

Next step

We size a steel strip coil packing machine in three steps:

  1. Submit your layout drawing with the coil ID, OD, width, weight, wrapping material and output target, to info@fhopepack.com.
  2. Receive a proposal within 48 hours, with the machine arrangement, the conveyor layout and the cycle check against your takt.
  3. Book a site survey so we confirm the slitter exit, the floor space and the operator position.
