Orbital Wrapper for Long Bars: Wrapping Three Bands at Set Points Instead of a Full Spiral

Executive summary This clip from our workshop shows our orbital wrapper for long objects wrapping three short bands along a round bar. The bar is centred in the ring by hand-wheel units, the ring wraps one band, the bar moves on and the next band is wrapped. Our F series rod wrapper handles products 200–500 mm across and 2,000–10,000 mm long, with ring speeds of 30–60 r/min. Below we cover band wrapping, the data and a worked example for time per band.

What the clip shows

The clip is filmed in our workshop, close to the ring.

Step What you see
Infeed A long round bar rests on rollers and passes through the centre of a grey ring frame
Clamping Hand-wheel centring units on each side hold the bar on the ring axis
Wrapping The ring turns and lays a short band of orange wrap round the bar at one position
Indexing The bar moves on and the ring wraps the next position, so the bar carries separate bands
Wrap head A close-up shows the wrap roll on its carriage beside the ring

The result is three short wrapped bands along the bar rather than a full spiral, which uses less material where the bands only need to hold or protect at set points.

Band wrapping or full spiral

  • Bands at set points. The ring wraps only where the bar or bundle needs holding, such as near the ends and the middle.
  • Full spiral. The bar travels through while the ring turns, so the wrap covers the whole length.
  • Same machine. Our rod wrapper sets the packaging position automatically, so the same ring can do either pattern.
  • Material choice. PE stretch film, knit belt or VCI paper can be used.

Rod wrapping machine data

Our published data for the F series rod wrapping machine:

Item Published value
Product OD 200–500 mm
Product length 2,000–10,000 mm
Ring speed 30–60 r/min
Wrapping speed 2–12 m/min
Overlap 20–90%
Wrap material PE stretch film, knit belt, VCI paper
Power 6.8 kW, AC 380 V 50 Hz or to order
Control PLC and HMI; speed by converter

Wrapping tension is set by a brake, and the machine alarms automatically on a fault.

Bands per bar

Worked example (illustrative). If each band takes 6 ring turns at 60 r/min, the ring needs 6 ÷ 60 = 0.1 minute, or 6 s, per band. Three bands then take about 18 s of ring time per bar, plus the indexing time between positions.

Selection checklist

Safety

The ring turns close to the centring units, and the operator sets the hand wheels before the cycle. We guard the ring zone to the risk assessment and set the controls so the ring turns only when the operator is clear. For CE markets we apply ISO 12100:2010 and EN 415-10:2014.

Engineering FAQ

Q: What is 3-band orbital wrapping? A: The ring wraps three short bands at set points along the bar instead of a full spiral.

Q: What sizes does the rod wrapper take? A: OD 200–500 mm and length 2,000–10,000 mm on our published range.

Q: How fast is the ring? A: 30–60 r/min, with wrapping speed 2–12 m/min for full spirals.

Q: Can it wrap a full spiral as well? A: Yes. Packaging position is set automatically, so the same ring can wrap bands or a spiral.

Q: What wrap materials can it use? A: PE stretch film, knit belt or VCI paper.

Q: How long does one band take? A: About 6 s for 6 ring turns at 60 r/min.

Q: Which standards apply? A: For CE markets, ISO 12100 and EN 415-10.

Next step

We size an orbital wrapper for long objects in three steps:

  1. Submit your layout drawing with product OD, length and weight, band pattern and pieces per hour, to info@fhopepack.com.
  2. Receive a proposal within 48 hours with the machine data and layout.
  3. Book a site survey so we confirm the floor space and line links.
