This article is written for the plant or production engineer and the purchasing manager who needs to answer those three questions before requesting a quotation. It explains how the machine spirals stretch film around a bundle that is moving axially through a rotating ring, how to calculate overlap and film consumption from wrapping speed and ring speed, and which material-specific practices keep thin-wall pipe round, decorative aluminium faces scratch-free and copper tube free of moisture stains.<\/p>\n<h2>Overview<\/h2>\n<iframe loading=\"lazy\" width=\"940\" height=\"535\" src=\"https:\/\/www.youtube.com\/embed\/aSVT1UCTvqc?rel=0\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe>\n<p>The video above shows the working principle in practice: a long bundle of extruded product travels through a ring that turns around it, laying stretch film in a continuous spiral. The core idea is simple \u2014 the bundle moves, the ring turns \u2014 and every parameter that matters (feed per turn, overlap, film per metre) follows from the ratio between those two motions.<\/p>\n<h2>How the horizontal orbital wrapper works: five points that matter<\/h2>\n<p><strong>1. Ring drive and speed control.<\/strong> The ring is driven through a friction wheel, and the friction is adjustable so the drive can be tuned rather than forced. Ring speed is set by an inverter, with soft start and soft stop. For long goods this matters more than it sounds: a ring that jerks up to speed can drag the film and pull a light plastic pipe bundle sideways as it enters.<\/p>\n<p><strong>2. Film carriage riding on the ring.<\/strong> The film carriage is mounted on the ring itself, and film tension is adjustable. Correct tension is what makes the film lie flat against round pipe surfaces and flat profile faces instead of bridging or digging in. Tension is set once per product family and checked whenever you change bundle size.<\/p>\n<p><strong>3. Unpowered roller tables.<\/strong> A 500 mm roller table sits in front of the ring and another behind it. The operator pushes the bundle through at a steady pace \u2014 there is no powered feed on this semi-automatic model. The human hand is effectively the wrapping-speed control, which is why the overlap maths below treats feed speed as the variable the operator sets.<\/p>\n<p><strong>4. Photocell and PLC sequencing.<\/strong> A photocell detects the bundle as it enters the ring area; the PLC starts the ring and stops it again when the bundle clears, returning the ring to a reset position so the next cycle begins identically. The operator does not time anything.<\/p>\n<p><strong>5. Optional film cutter and feeder.<\/strong> With the optional cutter and feeder, the machine clamps the film tail, cuts it at the end of the wrap and holds the film ready for the next bundle. Without it, the operator tucks and cuts the tail manually \u2014 acceptable at low output, worth specifying if bundles per hour is a serious number.<\/p>\n<h2>S300 quotation data<\/h2>\n<p>Use this table to cross-check your own product against the machine envelope.

That means the bundle&#8217;s diagonal \u2014 not just its width or height \u2014 must stay well under 450 mm. A bundle that measures 300 \u00d7 300 mm has a diagonal of roughly 424 mm and will be tight or impossible; a 250 \u00d7 250 mm bundle (diagonal \u2248 354 mm) leaves room for the carriage and film. Confirm your net maximum bundle width and height at quotation stage rather than estimating from nominal pipe size.<\/p>\n<h2>Overlap and film consumption: the maths that ties push speed to ring speed<\/h2>\n<p>Three formulas connect the operator&#8217;s push speed, the ring speed and the film width:<\/p>\n<ul>\n<li><strong>Feed per ring turn (mm)<\/strong> = wrapping speed (mm\/min) \u00f7 ring speed (r\/min)<\/li>\n<li><strong>Overlap (%)<\/strong> = (1 \u2212 feed per turn \u00f7 film width) \u00d7 100<\/li>\n<li><strong>Film per metre of bundle (m)<\/strong> \u2248 bundle perimeter (m) \u00d7 turns per metre<\/li>\n<\/ul>\n<p><strong>Worked example (estimation only).<\/strong> Suppose the operator pushes the bundle at 10 m\/min and the ring runs at 120 r\/min. The bundle advances 10,000 \u00f7 120 \u2248 83 mm per ring turn. With 150 mm film, the overlap is (1 \u2212 83 \u00f7 150) \u00d7 100 \u2248 45%. If the bundle has a perimeter of 0.6 m, it receives 1,000 \u00f7 83 \u2248 12 turns per metre, so film consumption is approximately 0.6 \u00d7 12 \u2248 7.2 m of film per metre of bundle \u2014 before stretch. Stretching the film at the carriage reduces actual consumption; treat the unstretched figure as a conservative budgeting number.<\/p>\n<p>The practical reading of these formulas: if you want more overlap, either slow the push or speed up the ring. If you want to cut film cost, a wider film at the same feed per turn raises overlap for free \u2014 or lets you push faster at the same overlap, raising output.<\/p>\n<h2>Best practices for pipe and tube surfaces<\/h2>\n<p><strong>Plastic pipe.<\/strong> Keep film tension low. Thin-wall pipe can oval under concentrated wrapping pressure, and an ovalsed bundle is a customer complaint before it is a packaging defect. Set tension so the film conforms without compressing.<\/p>\n<p><strong>Aluminium profile.<\/strong> Run a higher overlap on decorative faces, and add paper or foam interlayers on sharp edges. Film alone on a mill edge will find the corner; the interlayer takes the point load.<\/p>\n<p><strong>Copper and steel tube.<\/strong> Wrap dry tube only. Moisture trapped under stretch film is the classic cause of staining and tarnish on copper \u2014 the wrap that protects the bundle from dirt can hold condensation against the surface. If tube comes off the line warm, let it cool and dry before wrapping.<\/p>\n<p><strong>Long bundles.<\/strong> Support the bundle on rollers on both sides of the ring. An unsupported span sags as it passes through, and a sagging bundle twists the spiral \u2014 you get a dense wrap at the ends and a loose one in the middle.<\/p>\n<p><strong>Bundle ends.<\/strong> Leave the ends open so the bundle can breathe, unless dust is the bigger risk for your product \u2014 in that case, cap the ends before wrapping.<\/p>\n<h2>Selection checklist before you request a quotation<\/h2>\n<ul>\n<li>Product: plastic pipe, aluminium profile, or copper\/steel tube<\/li>\n<li>Bundle width, height and length (check the diagonal against the 450 mm ring)<\/li>\n<li>Bundle weight \u2014 5\u201350 kg on this semi-automatic model<\/li>\n<li>Bundles per hour<\/li>\n<li>Film only, or paper plus film<\/li>\n<li>Manual push, or powered conveyors for heavier or faster duty<\/li>\n<\/ul>\n<h2>Safety: design references, not a certificate claim<\/h2>\n<p>The ring area is guarded, and the ring uses soft start and soft stop to limit unexpected movement.
