Samenvatting Eye-through wrapping passes film through the centre of a coil and round its wall, so the whole coil is covered, inside and out. Our coil packaging machine does this with a ring that opens to take the coil, while rollers turn the coil slowly so the film builds up all the way round. Wraps follow from the buitendiameter en overlappen set there. Both are set per project.

Wat de video laat zien

An operator sets a coil upright on the support rollers of our green coil wrapper. The ring passes through the coil’s eye and carries the film roll round the coil wall.

As the ring turns, the rollers turn the coil slowly, and blue film builds up round it. The operator steps away and the machine runs on its own until the coil is fully covered. A control cabinet with a signal tower stands beside it, and the fhopepack.com mark runs along the foot of the clip.

How eye-through coil wrapping works

Stap voor	Wat gebeurt
Laden	The coil is stood on its edge on the support rollers
Ring door het oog	The ring opens, passes through the coil eye and closes
Wikkel	The ring carries film round the coil wall
Spoelwikkeling	The rollers turn the coil so each wrap is laid next to the last
Finish	The film is cut and the coil lifted off

Two motions work together: the ring wraps round the wall, and the coil turns. Their speed ratio sets the overlap.

Estimating wraps per coil

The wraps are closest together at the inside diameter and furthest apart at the outside, so full cover is worked out at the outside. Illustrative example for a coil with 508 mm ID, 1,000 mm OD and 300 mm width, wrapped with 100 mm film at half overlap on the outside:

Item	Waarde
OD omtrek, π × 1,000	ongeveer 3,142 mm
Advance per wrap at the OD, half of 100 mm	50 mm
Wikkels voor volledige dekking, 3,142 ÷ 50	over 63
Advance at the ID, 1,596 mm ÷ 63	ongeveer 25 mm
Spoelwand, (1,000 − 508) ÷ 2	246 mm
Sectieomtrek, 2 × (246 + 300)	1,092 mm
Film op rol, 63 × 1.092 m	over 69 m

At the inside the same wraps sit much closer, so the eye gets several layers. That is why the inside is rarely the weak point.

Film, paper or both

Wikkel	Gebruik
Rekfolie	Keeps out dust and damp
VCI-papier of -film	Slows rust on steel coils
Geweven tape	Tougher cover for rough handling

Copper coils mainly need dust and moisture cover. Steel coils for long transit often get a VCI layer under the film.

Bediening en veiligheid

The ring and the coil both turn during wrapping. Keep hands clear of the ring opening and the support rollers, and stop the machine before lifting a coil on or off.

De geldende normen zijn afhankelijk van de bestemmingsmarkt. Voor CE-markten beschrijft ISO 12100 de risicobeoordelingsmethode en EN 415-10 de algemene eisen voor verpakkingsmachines.

Veelgestelde vragen over techniek

Q: What is eye-through wrapping? A: Film passes through the coil centre and round the wall, covering the coil inside and out.

Q: Why is overlap set at the outside diameter? A: That is where wraps sit furthest apart. Set the overlap there and the inside is covered too.

Q: How many wraps does a coil need? A: OD circumference divided by the advance per wrap. Our 1,000 mm OD example needs about 63.

Q: Does it suit copper and steel? A: Yes. The film type changes: VCI layers are common on steel for long transit.

Q: Does the operator stay at the machine? A: In the video the operator loads the coil, then the machine runs on its own.
