Alum profile stretch wrapping machine with V-shape rollers

An orbital wrapping machine with V‑shape rollers is a semi‑automatic stretch wrapper designed for long, heavy aluminum extrusions. It uses a rotating ring (an orbital—a ring that rotates around the product) to apply stretch film around the profile while V‑shaped support rollers center and stabilize the bundle. This guide is based on the client inquiry referencing the E‑300 model.

🛠️ Core Questions

What is an aluminum profile orbital wrapping machine with V‑shape rollers?

It is a semi‑automatic orbital stretch wrapper that uses V‑shaped support rollers to guide and center long aluminum extrusions up to 7000 mm length, 150 mm width, 50 mm height, and up to 50 kg weight, applying stretch film in a continuous spiral for protective bundling. The rotating ring moves along the profile while V‑rollers keep the bundle stable and prevent rotation. This design is common for extrusions supplied to construction, automotive, and window‑frame industries. Based on the supplied client inquiry, typical delivery includes a machine model like E‑300 (the model referenced in the client inquiry) with quotation tailored to these dimensions.

How do V‑shape rollers improve wrapping quality?

V‑shape rollers hold the aluminum profile in a centered position, preventing lateral shifting and reducing film wrinkles. The rollers’ angled surfaces match the rectangular cross‑section of the extrusion, distributing weight evenly. This eliminates the need for manual adjustment during the wrapping cycle. Key Point: V‑rollers also allow a single machine to handle a range of profile widths (e.g., 50–150 mm) without changing tooling. For the specified profile (7000×150×50 mm), the V‑rollers maintain constant contact, which may reduce waste compared to manual wrapping. All performance figures are typical and should be verified with supplier quote.

What type of film is used, and how is it applied?

Standard stretch film—linear low‑density polyethylene (LLDPE, a common stretch film material) or PVC—in widths of 250–500 mm is applied semi‑automatically by the orbital ring while the profile rests stationary on the V‑rollers. The operator pulls the film tail, then triggers the rotating ring to spiral‑wrap the load. Overlap and tension are adjustable via a manual brake or electronic tensioner, depending on the machine model. For the client’s requirements, stretch film is specified as the protective packaging material. Maximum bundle weight is up to 50 kg per unit. After wrapping, the film tail is cut manually.

Is this machine fully automatic or semi‑automatic?

The machine described in the inquiry is semi‑automatic: the operator places the profile on the V‑rollers, secures the film start, and then presses start—the ring rotates automatically and the carriage advances along the profile. The operator manually cuts and seals the film at the end. This balance between automation and operator control is typical for mid‑volume production lines. Fully‑automatic versions exist with automatic film feeding, cutting, and bundling handling, but the requested machine in the Riyadh inquiry is semi‑automatic, which reduces upfront cost and maintenance complexity.

What delivery conditions apply for Riyadh, Saudi Arabia?

Pricing is requested on FOB and CIF Riyadh terms, with delivery lead time, installation, and commissioning details. Confirm floor space and power requirements with supplier layout drawing. Based on the original email, the buyer also requests machine dimensions and layout drawing, production capacity (bundles per hour), and warranty period. A typical semi‑automatic orbital wrapper for profiles of this size (7000 mm length) occupies roughly 8 m × 1.5 m floor space and requires 380 V/3‑phase power. The supplier (FHOPEPACK) is specialized in such machines. Ask supplier for exact cycle time for your profile—commonly ranges from 15–25 bundles per hour depending on profile length and operator speed.

🏗️ Advanced Questions

How is the production capacity calculated for this machine?

Capacity depends on profile length, ring rotation speed (typically 30–60 rpm), and carriage travel speed (10–20 m/min). For a 7 m profile, one wrapping cycle takes around 1.5–2 minutes, giving 20–30 bundles per hour under ideal conditions. The actual rate is lower when including loading, film start/stop, and unloading. Ask supplier for exact cycle time for your profile. Key Point: The E‑300 (the model referenced in the client inquiry) or equivalent model may include a variable frequency drive to adjust speed based on profile stiffness.

Can the machine handle different profile shapes and sizes?

Yes—the V‑shape rollers and adjustable ring diameter accommodate diverse rectangular, square, or T‑shaped extrusions, as long as the maximum cross‑section stays within 150×50 mm. The machine can handle profiles from 1 m to 7 m length in a single pass. For longer profiles (over 9 m), a longer track or multiple passes may be needed. The supplier typically offers interchangeable roller sets or adjustable V‑blocks for different widths. Verify with supplier: the E‑300 machine likely accepts widths 50–200 mm.

What automation features are usually available for this model?

Common automation options include automatic film pre‑stretch, programmable logic controller (PLC) with touchscreen, film tail sealing, and bundle counter. The basic semi‑automatic version has manual film start and cut. The client in Riyadh asked for “automation features available” – typical add‑ons are:

• Pneumatic film cutter

• Digital film tension control

• Length presetting for ring travel

• Warning lights and safety interlocks

Key Point: For a semi‑automatic machine, the operator is required for loading and film handling; automation reduces labor intensity but not labor headcount.

What installation and commissioning support is standard?

Standard support includes a technician visit for 2–3 days, machine calibration, training for two operators, and a remote hotline. For Riyadh delivery, the supplier may offer on‑site commissioning as part of CIF terms or as a separate service. The buyer should confirm whether the quotation includes travel and accommodation costs. Based on the inquiry, the warranty period is typically 12 months from commissioning, covering parts and labor (excluding consumables). Documented after‑sales support (phone, video) is often provided.

How does stretch film consumption compare to other wrapping methods?

Compared to manual wrapping, this orbital machine reduces film consumption by 30–50 % due to controlled tension and overlapping, while still using standard stretch film. The V‑roller centering minimizes film waste caused by misalignment. For a bundle weighing up to 50 kg, a typical film usage per wrap is 0.3–0.5 kg of 20 µm stretch film. Over a year of 2000 operating hours, this can translate to significant cost savings. All performance figures are typical and should be verified with supplier quote.

📈 Selection Checklist

Tip: Before ordering, request a test wrap of your own profile (7000 × 150 × 50 mm) on a similar machine at the supplier’s facility or via a video sample. This verifies film fit, roller centering, and film tail handling. Confirm floor space and power requirements with supplier layout drawing.
