> **Shrnutí**
> We build horizontal orbital wrappers that spiral stretch film around a steel tube bundle while the bundle travels through a rotating ring, so the tubes never turn. Our pipe orbital wrapper handles **2000–8000 mm** pipe lengths, 300–2000 mm bundle OD and 100–5000 kg bundles. Wrapping speed runs at 2–12 m/min with 20–90% overlap. This guide covers the process, specifications, material choice and a **wrap-time method** for your bundle.

Jak se orbitálně ovíjí svazek ocelových trubek, krok za krokem
V tomto 142sekundovém videu jsme sestavili balicí stroj pro svazky ocelových trubek. Sleduje jeden páskovaný svazek kulatých trubek, který prochází strojem. Každý níže uvedený krok přidává technické nastavení, které za ním stojí:
1. **0–20 s, infeed.** The bundle arrives already strapped from the bundling line and travels on the powered infeed conveyor towards the ring, so the wrapper receives a bundle that holds its shape.
2. **24–44 s, program set.** Our operator sets ring speed and conveyor speed on the control cabinet beside the line before the wrap starts. Together they fix the film overlap on the bundle.
3. **About 72 s, centring and feed.** Green side rollers close on the bundle and guide it into the ring, so the bundle axis runs through the middle of the ring.
4. **76–108 s, orbital wrapping.** The ring rotates around the bundle while the conveyor moves it forward. The tubes stay still; only the film carriage turns. Overlap comes from the ratio of ring speed to conveyor speed. The automatic film draw-back tension device keeps film tension steady on both small and big bundles.
5. **108–140 s, cut and discharge.** The film is cut at about 108–116 s, and from 120 s the bundle travels out on the outfeed conveyor fully covered in blue film, end to end.
Princip otáčení prstence a pohybu svazku je pro ocel důležitý. Dlouhé svazky o hmotnosti až 5000 kg by se jen těžko otáčely a volné trubky by se při otáčení posouvaly.

Velikost svazku: změřte přes rohy
Vnější průměr svazku je kružnice, proto změřte největší rozměr průřezu svazku:
- **Hexagonal bundles:** across-corners = across-flats × 2 ÷ √3. A bundle 500 mm across the flats is about 577 mm across the corners.
- **Square or rectangular bundles:** use the diagonal. A 400 × 400 mm bundle has a 566 mm diagonal.
- **Range check:** the largest dimension must sit inside 300–2000 mm, and the length inside 2000–8000 mm.
- **Short bundles:** below 2000 mm, the bundle must still bridge the gap between the infeed and outfeed conveyors.
Doba balení a propustnost na balíček
Doba obalování se odvíjí od tří nastavení:
1. **Pitch per ring turn** = film width × (1 − overlap). With 500 mm film at 50% overlap, the pitch is 250 mm.
2. **Travel speed** = ring speed × pitch. At 40 r/min and 250 mm pitch, the bundle travels at 10 m/min, inside the 2–12 m/min range.
3. **Wrap time** = bundle length ÷ travel speed. A 6000 mm bundle at 10 m/min wraps in 36 s.
Dva pracné limity:
- **Fastest case:** 8000 mm at the 12 m/min ceiling wraps in 40 s. At 60 r/min that speed gives a 200 mm pitch, which is 60% overlap.
- **Heavy-protection case:** 90% overlap gives a 50 mm pitch. At 40 r/min that is 2 m/min, so a 6000 mm bundle takes 180 s.
Add the head and tail wraps, film cut and conveyor transfer to get the full cycle. Then compare it with your mill's bundle rate.
Balicí materiál pro ocelové trubky: fólie, pletený pás nebo VCI papír
Naše balicí linka na trubky používá tři typy materiálů. Vyberte si podle přepravní trasy a skladování:
- **PE stretch film:** dust and moisture protection for covered storage and road transport. Overlap of 50% or more gives two film layers over the whole bundle.
- **VCI paper:** a corrosion-inhibiting layer for bare carbon steel on long sea routes. Run it as the inner layer, then cover it with film. Both can go on in one pass when the ring is larger than the bundle: the ring carries two different materials, and even three.
- **Knit belt:** abrasion protection for heavy bundles that are lifted by sling or chain.
Barevná fólie, jako například modrá fólie na našem stroji ve videu, usnadňuje rozlišení jakostí produktů na zahradě.
Integrace a uspořádání linky s trubkovou mlýnou
Po vytvoření svazku a páskování umístíme obal a naplánujeme rozvržení podle tří bodů:
- **Strapping first:** in our steel tube packing lines, bundle forming and strapping come before the wrapper. The film covers a bundle that already holds its shape.
- **Conveyor length:** both conveyors must carry the longest bundle, up to 8000 mm, on each side of the ring.
- **Offline option:** a forklift-loaded wrapping station handles lower volumes without connecting to the mill line.
Bezpečnost v okolí horizontálního orbitálního obalu
Hlavní nebezpečí představují rotující kruh a dopravníky. Naše rozvržení používají:
- A fenced wrapping zone around the ring, with operators outside the fence during the cycle.
- Program changes made at the touch panel outside the fence, not at the ring.
- Gloves when handling bare tube ends, which have sharp edges.
Platné normy závisí na cílovém trhu. Pro trhy CE stanoví norma ISO 12100 metodu hodnocení rizik a norma EN 415-10 stanoví obecné požadavky na balicí stroje.

Často kladené otázky k inženýrství
Q: Does the bundle rotate during orbital wrapping?
A: No. The ring rotates at 20–60 r/min around the bundle while the conveyor carries it through at 2–12 m/min. The tubes stay still, which keeps a strapped bundle in shape.
Q: What is the longest tube bundle the machine can wrap?
A: The standard range is 2000–8000 mm pipe length, with bundle OD 300–2000 mm and weight 100–5000 kg. Longer bundles need longer conveyors on both sides of the ring.
Q: How long does it take to wrap one bundle?
A: Wrap time is bundle length ÷ travel speed. A 6000 mm bundle at 10 m/min takes 36 s at 50% overlap with 500 mm film. Add head and tail wraps and transfer time for the full cycle.
Q: Can the machine wrap with VCI paper instead of film?
A: Yes. The machine runs PE stretch film, knit belt or VCI paper. For sea freight, VCI paper goes on as the inner layer with stretch film over it at 50% overlap or more. Both layers go on in one pass when the ring is larger than the bundle, because the ring can carry two different materials, even three.
Q: What overlap should I set for export bundles?
A: Start at 50%, which gives two layers everywhere. Go higher, up to 90%, for long sea routes or outdoor storage. Every overlap step slows travel speed, so check the wrap time.
