This line links three stations in one flow: a tilter that lays each coil flat, a through-eye wrapper that binds it, and a stacker that builds a pallet. Coils run from 30 to 4,000 kg, with outer diameters of 500\u20131,500 mm and strip widths of 8\u2013500 mm, at 20\u201340 coils per hour.<\/p>\n<\/blockquote>\n<iframe loading=\"lazy\" width=\"940\" height=\"535\" src=\"https:\/\/www.youtube.com\/embed\/1uZWkLX4Llc\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe>\n<hr \/>\n<h2>Table of Contents<\/h2>\n<ul>\n<li><a href=\"#why-tilt-wrap-and-stack-in-one-line\">Why tilt, wrap and stack in one line<\/a><\/li>\n<li><a href=\"#the-three-stations\">The three stations<\/a><\/li>\n<li><a href=\"#coil-range-and-performance\">Coil range and performance<\/a><\/li>\n<li><a href=\"#worked-example-one-pallet-of-slit-coils\">Worked example: one pallet of slit coils<\/a><\/li>\n<li><a href=\"#manual-assist-or-fully-automatic\">Manual-assist or fully automatic<\/a><\/li>\n<li><a href=\"#selection-checklist\">Selection checklist<\/a><\/li>\n<li><a href=\"#safety\">Safety<\/a><\/li>\n<li><a href=\"#engineering-faq\">Engineering FAQ<\/a><\/li>\n<li><a href=\"#next-step\">Next step<\/a><\/li>\n<li><a href=\"#related-reading\">Related reading<\/a><\/li>\n<li><a href=\"#sources\">Sources<\/a><\/li>\n<\/ul>\n<hr \/>\n<h2>Why tilt, wrap and stack in one line<\/h2>\n<p>On a slitting line, coils leave the recoil mandrel eye-horizontal. A narrow coil with a high OD-to-width ratio is unstable in that position and prone to tipping. Tilting, wrapping and stacking by crane or standalone mobile upenders turns packing into a bottleneck and adds the risk of strip telescoping, wrap indentation and transverse edge damage.<\/p>\n<p>Running the three steps inline keeps packing in step with the slitter:<\/p>\n<ol>\n<li><strong>Orientation:<\/strong> the tilter lowers the coil 90\u00b0 to eye-vertical, where it lies flat on conveyor rollers and cannot tip.<\/li>\n<li><strong>Containment:<\/strong> the flat coil passes through the wrapping ring, which lays material through the bore and around the outside diameter.<\/li>\n<li><strong>Palletising:<\/strong> the stacker places the wrapped coil on a pallet without a second rigging step.<\/li>\n<\/ol>\n<hr \/>\n<h2>The three stations<\/h2>\n<h3>1. Tilter (down-ender)<\/h3>\n<p>The tilter moves the slit coil from eye-horizontal to eye-vertical on the conveyor. High-throughput lines handling multi-ton coils use a two- or four-arm turnstile with a heavy-duty down-ender and a traversing coil car; lighter strip coils use an electro-mechanical tilting basket, which turns over faster and takes less floor space.<\/p>\n<h3>2. Eye-through wrapper<\/h3>\n<p>The coil rests on a motorised dual-roller cradle that turns it about its own axis while the ring carries the packaging material through the bore and around the outside diameter.<\/p>\n<ul>\n<li><strong>Drive:<\/strong> ring and cradle rollers run on inverter drives, so overlap is set between 10% and 90%.<\/li>\n<li><strong>Tension:<\/strong> a mechanical friction brake or powered pre-stretch carriage holds wrap tension steady and avoids edge creasing on thin strip.<\/li>\n<li><strong>Media:<\/strong> stretch film (LLDPE\/PE), VCI anti-rust paper, woven HDPE or multi-layer barrier laminates.<\/li>\n<\/ul>\n<h3>3. Stacker (palletising unit)<\/h3>\n<p>The stacker lifts the wrapped coil from the exit conveyor and centres it on a wooden or steel pallet, building a multi-coil stack. The head is chosen for the metal:<\/p>\n<ul>\n<li><strong>Electromagnetic head:<\/strong> carbon and ferritic steels only; not for non-ferrous or high-finish stock.<\/li>\n<li><strong>Vacuum matrix:<\/strong> flat-faced coils, stainless, aluminium and brass where surface marking must be avoided.<\/li>\n<li><strong>Mechanical gripper or scissor arm:<\/strong> grips by the outer perimeter or under the bore ledge, giving fail-safe support for heavy, oily or irregular packs.<\/li>\n<\/ul>\n<p>Radial strapping, inline weighing and label applicators can be added along the conveyor between wrapping and stacking.<\/p>\n<hr \/>\n<h2>Coil range and performance<\/h2>\n<h3>Line capability<\/h3>\n<ul>\n<li>Coil weight: 30 to 4,000 kg<\/li>\n<li>Coil OD: 500 to 1,500 mm (to 2,100 mm on

These figures are illustrative and must be checked against the actual strip width and coil weight of your run.<\/p>\n<hr \/>\n<h2>Manual-assist or fully automatic<\/h2>\n<p>A fully automatic line carries the coil from slitter exit to pallet with no operator handling: tilter, wrapper, strapper and stacker exchange coils through conveyor transfers and permissive signals.<\/p>\n<p>A manual-assist configuration keeps an operator at the tilter or stacker, using pendant control for loading and pallet building while the wrapper runs its own cycle. It costs less and tolerates irregular coil shapes, but output depends on the operator and is lower than the 20\u201340 coils per hour of the automatic line.<\/p>\n<p>The decision usually turns on three points: coil weight (above roughly 1 t, manual handling stops being practical), strip quality requirements (VCI and barrier wraps favour automatic tension control), and available floor space for the transfer conveyors.<\/p>\n<hr \/>\n<h2>Selection checklist<\/h2>\n<ul>\n<li><strong>Coil envelope:<\/strong> minimum and maximum OD, ID and strip width, including the widest and narrowest slits in the schedule.<\/li>\n<li><strong>Coil weight:<\/strong> confirm against the 3 T \/ 5 T \/ 10 T tilter range, and check the wrapper limit separately.<\/li>\n<li><strong>Throughput:<\/strong> coils per hour from the slitter, compared with the 20\u201340 coils\/hour line rate.<\/li>\n<li><strong>Stack plan:<\/strong> coils per pallet, stack height and pallet rating.<\/li>\n<li><strong>Wrap specification:<\/strong> film, VCI paper or barrier laminate, and the overlap you need.<\/li>\n<li><strong>Stacker head:<\/strong> magnetic, vacuum or mechanical, chosen by material.<\/li>\n<li><strong>Ancillary stations:<\/strong> strapping, weighing and labelling, and where they sit in the flow.<\/li>\n<li><strong>Utilities and layout:<\/strong> 380V three-phase supply, 4\u20136 bar air, and conveyor runs between stations.<\/li>\n<\/ul>\n<hr \/>\n<h2>Safety<\/h2>\n<p>The line is designed under the EN 415-10 packaging-machinery framework with a hazard assessment to ISO 12100:2010.<\/p>\n<ul>\n<li><strong>Guarding:<\/strong> fixed and interlocked guards enclose the tilter, ring and stacker zones; the exact arrangement follows the site risk assessment.<\/li>\n<li><strong>E-stops:<\/strong> emergency-stop devices at each station, with reset at the operator position.<\/li>\n<li><strong>Load security:<\/strong> verify coil stability before tilting and confirm the stack is centred before the stacker releases.<\/li>\n<li><strong>LOTO:<\/strong> isolate power and air before any intervention inside the ring or under the stacker head.<\/li>\n<\/ul>\n<hr \/>\n<h2>Engineering FAQ<\/h2>\n<h3>Why tilt the coil before wrapping?<\/h3>\n<p>A narrow coil standing eye-horizontal is unstable and can tip; laid flat it is supported across its full face and can be wrapped through the bore without re-orientation.<\/p>\n<h3>Can the wrapper handle strip narrower than 100 mm?<\/h3>\n<p>The FPS-300 covers 100\u2013300 mm.
