Резюме Our compact horizontal orbital stretch wrappers spiral film around single aluminum profiles and small bundles as they pass through the rotating ring. Three standard models cover cross-sectional package diagonals of 50–100 mm (E100), 50–200 mm (E200) и 100–300 mm (E300). Because film width, linear conveyor speed, and ring rotational speed dictate surface overlap, we engineer ring geometry and drive ratios simultaneously to guarantee protective integrity and throughput.

Как работает оболочка профиля
Our horizontal orbital stretch wrapper transports extrusions along motorized infeed and outfeed roller conveyors directly through a central rotating ring. A photoelectric sensor tracks the profile leading edge, triggering the orbital ring drive, determining the exact wrapping start position, and controlling the trailing-edge cutting cycle. Non-marking, polyurethane-coated side guide rollers maintain the workpieces firmly along the conveyor centerline, preventing lateral shifting or orbital torque twist during high-speed rotation.
Ring rotation and linear conveyor travel are powered by independent variable-frequency drives (VFD). This configuration allows operators to adjust ring RPM and linear travel speed separately via the PLC touch screen. The drive system incorporates controlled S-curve acceleration and deceleration ramps, ensuring soft starts, smooth stops, and accurate automatic homing so that every profile bundle begins its wrapping cycle at the exact mechanical reference point.
Три компактные модели
All three standard compact models share an identical material handling footprint: a 2,000 mm motorized infeed conveyor and a 2,000 mm motorized outfeed conveyor. The mechanical film carriage accepts standard stretch film rolls with an external diameter of 100–200 mm mounted on a standard 50 mm (2-inch) core.

Our technical specifications separate wrapping linear speed through the ring from conveyor transit speeds. Because structural profiles with irregular fins create varying aerodynamic and mechanical resistance, wrapping speeds for intermediate cross-sections (E200) are matched to your profile drawings during application review.
Измерительный диаметр упаковки
The effective package outside diameter (OD) corresponds to the maximum cross-sectional diagonal of the profile or packed bundle, rather than width or height alone. The orbital ring clearance must accommodate this diagonal plus carriage clearance margins.
Package OD = √(Width² + Height²)
Illustrative engineering calculations:
- 60 × 40 mm architectural extrusion:
√(60² + 40²) = √(3600 + 1600) ≈ 72.1 mm. Fits within the E100 operational envelope (50–100 mm). - 150 × 120 mm extrusion bundle:
√(150² + 120²) = √(22500 + 14400) ≈ 192.1 mm. Требуется E200 or E300 . - 250 × 150 mm industrial bundle:
√(250² + 150²) = √(62500 + 22500) ≈ 291.5 mm. Fits within the E300 envelope (100–300 mm).
For heavy extrusions or master packaging exceeding 300 mm OD, our engineering line transitions to heavy-duty horizontal orbital wrappers accommodating 300–1,500 mm envelopes.
Скорость, ширина пленки и перекрытие
With each full revolution of the orbital ring, the profile moves forward by a specific pitch distance, generating a continuous helical spiral. This linear displacement per revolution is calculated as:
Advance Pitch (mm/rev) = (Linear Wrapping Speed in m/min × 1,000) ÷ Ring Speed in RPM
The advance pitch directly governs the surface overlap ratio. To achieve a nominal 50% overlap for transit surface protection, the linear advance pitch must not exceed half of the applied film roll width:
Max Advance Pitch (50% Overlap) = Film Width ÷ 2
| Модель | Ширина пленки | Скорость кольца | Max Advance for 50% Overlap | Max Linear Speed at 50% Overlap |
|---|---|---|---|---|
| E100 | 100 мм | 120 об/мин | 50 mm / rev | 6.0 м/мин |
| E300 | 200 мм | 90 об/мин | 100 mm / rev | 9.0 м/мин |
The theoretical maximum speed of 15 m/min on the E100 is achieved only at lower overlap percentages (e.g., 20–30% for internal transport). For a standard 6 m profile running at 6 m/min under 50% overlap, net transit wrapping time is exactly 60 seconds, excluding pneumatic cut, clamping, and conveyor transfer cycles. Kinematic operational parameters are pre-programmed via PLC recipes during factory acceptance testing.
Беспилотная обработка пленки
Each wrapper integrates an automatic pneumatic clamping and cutting unit for fully hands-off, unmanned cycles. At cycle start, the pneumatic tail holder positions the film web across the profile path. As the ring rotates, the film is anchored against the workpiece; the clamp then releases automatically. At cycle conclusion, an integrated pneumatic blade cuts the film tail clean, and the holding mechanism secures the web for the next bundle.
Film tension is controlled through an adjustable mechanical friction brake with roller compensation. For delicate thin-wall profiles or fragile powder coatings, the E100 offers an optional powered pre-stretch film carriage providing 100–250% mechanical elongation to reduce unit containment force while minimizing plastic consumption. Conveyor options across all models include non-marking polyurethane rollers, modular PVC flat belts, or driven chain tracks for customized infeed integration.

Часто задаваемые вопросы по инженерным вопросам
Q: Which orbital model is required for a single 60 × 40 mm aluminum profile?
A: The E100 model. Its calculated diagonal is √(60² + 40²) ≈ 72.1 mm, which sits cleanly within the E100 working range of 50–100 mm OD.
Q: Can the E100 operate at 15 m/min while maintaining a 50% film overlap? A: No. At the maximum ring rotational speed of 120 RPM and using a standard 100 mm film roll, the maximum allowable linear travel speed for a 50% overlap is 6.0 m/min. Achieving 15 m/min requires dropping the overlap to approximately 20%.
Q: Does the system require manual cutting or film taping between cycles? A: No. All models include an automatic pneumatic film clamp-and-cut station. The film tail is clamped at the start, wrapped in, pneumatically sliced with a heated or serrated cutter, and held firmly for the subsequent workpiece.
Q: What is the minimum workable profile length? A: Standard machines process workpieces down to 1,000 mm. Shorter profiles require specialized intermediate bridge roll transitions to bridge the gap across the orbital ring center.
Q: What equipment options exist for bundle cross-sections larger than 300 mm? A: Packages exceeding 300 mm OD transition to our heavy-duty horizontal orbital wrappers, which provide ring working envelopes from 300 mm up to 1,500 mm.
