Executive summary A compact orbital stretch wrapping machine for long products feeds round or narrow items over V-shape rollers that hold them on the centre line, so the film ring wraps them evenly as they pass through. Below we explain the V-shape feed, film pitch setting, and the data of our equivalent E300 horizontal stretch wrapper (bundle OD 100–300 mm).

Machine layout and the V-shape feed
The layout of a compact orbital wrapper integrates product transport, dynamic centring, and continuous film application into a single linear workflow:
| Subsystem / Station | Engineering role and function |
|---|---|
| Infeed conveyor & control cabinet | Houses the PLC and frequency inverters; the infeed bed receives long profiles and advances them toward the wrapping station. |
| V-shape guide roller assemblies | Dual-face inclined rollers physically capture round, square, or narrow profiles to maintain centre-line alignment prior to entry into the ring. |
| Orbital rotating ring & film carriage | Supported behind a perimeter safety enclosure, the rotating ring carries the film tension carriage smoothly around the advancing bundle. |
| Outfeed conveyor | Powered outfeed rollers discharge the wrapped bundle continuously, maintaining linear support while keeping operators outside the automated envelope. |
Why a V-shape roll feed
A flat roller lets a round bar or a narrow profile drift sideways under operating vibration. Off-centre, the film lands unevenly and the rotating ring can touch the product. A V-shape roller fixes that:
- Self-centring. The V cradles round and narrow products on the machine centre line.
- Even wrap. With the product centred, film tension is uniform all round.
- Less setup. Different diameters sit in the same V without side guides to reset.
- Gentle contact. The product rides on two roller faces instead of rolling or scuffing across a flat bed.
For flat bundles or panels, flat rollers with side guides are better suited; the V feed is optimized for round, square, or narrow long products. Across our broader orbital machine family, ring rotation and conveyor speeds are driven via variable frequency inverters, allowing precise film tension adjustment and touch-panel overlap control [manufacturer rating]. For lower volumes, see our semi-automatic orbital stretch wrapping machine.
Our equivalent solution: E300 data
Our equivalent orbital wrapper for profiles, pipe, and bar is the E300 horizontal stretch wrapper:
| Item | E300 value |
|---|---|
| Bundle OD | 100–300 mm |
| Product length | Over 1,000 mm |
| Bundle weight | 15–100 kg |
| Ring speed | 20–90 r/min |
| Conveyor speed | 6–12 m/min |
| Wrapping speed (published) | 5–15 m/min |
| Film overlap | 10% to 90% |
| Film roll | OD 100–200 mm, width 100–200 mm, core ID 50 mm |
| Conveyors | 2,000 mm in and out, motor driven |
| Power | About 2.5 kW, 380 V, 60 Hz |
The E300 incorporates automatic film feeding and cutting, PLC control, photocell bundle detection, and an inverter-driven ring [manufacturer rating]. The machine is rated for heavy-duty industrial service up to 7,200 effective working hours per year [manufacturer rating].
Film pitch and line speed
Each ring turn lays one band of film. To achieve a specific film overlap, the product must advance by a precise pitch per revolution:
Advance per turn = Film Width × (1 − Overlap)
Worked example (illustrative). With 200 mm film at 50% overlap, the advance is 200 × (1 − 0.5) = 100 mm per turn. At a ring speed of 90 r/min, the conveyor speed is:
Conveyor Speed = 100 mm × 90 r/min = 9,000 mm/min = 9 m/min
This 9 m/min operating point falls safely inside the standard E300 conveyor range of 6–12 m/min. In horizontal orbital wrapping systems, frequency inverters synchronize the conveyor drive with ring rotation to maintain the target overlap across acceleration and deceleration ramps [manufacturer rating]. For heavier mechanical protection, raise the overlap percentage and reduce the conveyor speed accordingly.
Selection checklist
- Product shape: round, square, profile or flat bundle.
- Product or bundle OD and length range.
- Bundle weight.
- Film width and target overlap.
- Output target per hour.
- Manual feed, or a link to the line before and after.
- Floor space for infeed and outfeed beds.
Safety
The orbital ring rotates at high angular velocity around the moving bundle. The operational ring area is fully enclosed within an interlocked wire-mesh guard, preventing worker access to pinch points and rotating carriages during the wrapping cycle. Once the bundle is placed onto the infeed bed, all operations proceed automatically with personnel remaining outside the safety zone. Film roll replacement, threading, and maintenance must only be performed when the machine has reached a full standstill and the drive is safely isolated.
For CE markets, the design and safety integration comply with ISO 12100:2010 for risk assessment and EN 415-10:2014 for packaging machine safety requirements.
Engineering FAQ
Q: What does the V-shape roll do? A: It centres round and narrow long products, so the ring wraps them evenly.
Q: Which product sizes does your equivalent machine take? A: The E300 takes bundles of 100–300 mm OD, over 1,000 mm long and 15–100 kg [manufacturer rating].
Q: How fast does it wrap? A: The ring rotates at 20–90 r/min and the conveyor runs at 6–12 m/min; the published wrapping speed is 5–15 m/min [manufacturer rating].
Q: How do I set the overlap? A: Overlap is adjustable from 10% to 90%; the conveyor speed follows from film width, overlap and ring speed.
Q: Does it cut the film by itself? A: Yes, the E300 has automatic film feeding and cutting.
Q: What film rolls and power does the E300 need? A: Film rolls of 100–200 mm OD and 100–200 mm width on a 50 mm core, and about 2.5 kW at 380 V, 60 Hz [manufacturer rating].
Q: Which standards apply? A: For CE markets, ISO 12100 and EN 415-10.
