Kokkuvõte Our vertical coil stretch wrapper stands the coil on its edge on PU rollers and passes a film ring through the eye, so film covers the bore, both faces and the outside in one pass. The FPS-800 takes coils of 800 to 1,400 mm OD, 400 to 800 mm wide and 200 to 1,000 kg, with overlap adjustable from 10% to 90%.

Why big coils are wrapped standing up

A big coil lying flat has one face on the pallet, so film cannot reach it. Standing the coil on its edge leaves the whole cross-section free; for coils that arrive flat, an upender ahead of the wrapper turns them.

The ring passes through the bore and round the outside, while the coil turns slowly on its rollers so every part of the ring path is covered. The result is a sealed package against dust, water and handling marks, which is what export coils and coils stored outdoors need.

How the eye-through cycle runs

A trolley carries the coil into the machine and sets it on the support rollers, so the crane or C-hook does not have to place it precisely.
The operator enters the coil OD, ID, width and weight on the touch screen, with the wrapping speed and number of layers.
The ring turns through the eye while the PU rollers rotate the coil, laying film in a spiral around the cross-section.
Inverter drives give a soft start and stop, so the ring and coil run smoothly without slipping.
At the end of the set layers the operator cuts the film tail by hand, and the trolley takes the wrapped coil out. If you want no hand cutting, the FPS-500 offers automatic cut and clamp.

FPS-800 spetsifikatsioonid

These are the values for our FPS-800; special coil sizes are possible per project.

Kirje	SPF-800
coil ID	508 mm
coil OD	800 et 1,400 mm
Mähise laius	400 et 800 mm
Rulli kaal	200 kuni 1,000 kg
Pakkematerjal	PVC, LLDPE, PE, paber või HDPE
Kattumine	10% kuni 90%, reguleeritav
võim	1.5 kW, 380 V 50 Hz 3-phase (adjustable)
Õhuvarustus	5 to 7 kgf/cm², optional
Kontroll	Siemens, Mitsubishi or Omron PLC; 7″ or 10″ touch screen
rullid	High-strength PU coating: grips the coil without scratching it

Worked example: overlap that still covers the OD

On an eye-through wrapper the film overlaps most in the bore and least on the outside, because the outside circumference is longer. If the overlap is set for the bore alone, the outside can end up with gaps.

Samm	Väärtus
Mähise ID / OD	508 / 1,400 mm
Bore circumference, π × 508	umbes 1,596 mm
Kile laius (illustratiivne)	100 mm
Largest advance per ring turn at the OD with no gap	100 mm
Same advance measured at the bore, 100 × 508 ÷ 1,400	umbes 36 mm
Overlap needed at the bore, 1 − 36 ÷ 100	umbes 64%
Ring turns per layer, 1,596 ÷ 36	umbes 44

So on this coil, an overlap of at least about 64% at the bore is needed for the outside to be closed, well inside the 10% to 90% range. A smaller coil OD lets you run less overlap and fewer turns; a wider film does the same.

FPS-800 or FPS-500

	SPF-800	SPF-500
coil OD	800 et 1,400 mm	700 et 1,400 mm
Mähise laius	400 et 800 mm	200 et 500 mm
Rulli kaal	200 kuni 1,000 kg	80 kuni 1,000 kg
coil ID	508 mm	508 / 610 mm
Pakkimisaeg	set by OD, overlap, layers and the inverter speed setting; we quote it per coil	20 kuni 45 sekundit mähise kohta
Lisad	trolley loading	two film rolls at once, e.g. LLDPE plus VCI; automatic cut and clamp

Choose the FPS-800 for wide coils up to 800 mm. The FPS-500 suits narrower slit coils, and its dual-roll option lets you lay a VCI film for rust protection in the same pass.

Ohutus ja EN 415-10

The standards that apply depend on the destination market. For CE markets, ISO 12100 sets the risk-assessment method and EN 415-10 sets the general safety requirements for packaging machines, including the rotating ring. Our FPS-800 has safety light curtains and emergency stops, and stops when an operator enters the protected zone.

Fixed fencing with interlocked access, together with the light curtains, should guard the rotating ring and the trolley path. The site risk assessment decides the exact layout. Load and unload with the crane only when the ring is stopped.

Inseneri KKK

Q: What coil sizes does the FPS-800 take? A: 800 to 1,400 mm OD, 508 mm ID, 400 to 800 mm wide and 200 to 1,000 kg.

Q: Which materials can it wrap with? A: PVC, LLDPE, PE, paper or HDPE.

Q: How much overlap should I set? A: Enough for the outside to close; for a 508 / 1,400 mm coil with 100 mm film, about 64% at the bore.

Q: Does it need compressed air? A: Air at 5 to 7 kgf/cm² is optional, depending on the configuration.

K: Millised ohutusstandardid kehtivad? V: CE-märgisega turgudel kehtivad ISO 12100 ja EN 415-10.
