A loading station receives the bare coil directly from the slitting line recoiler, crane C-hook, or coil car. An eye-through wrapper covers the metal coil through its center eye and over its cylindrical wall, after which motorized transfer, lifter, or turning stations carry it between active process zones. A dedicated strapping station applies precision radial and circumferential bands, and an automated discharge station transfers the fully wrapped and strapped bundle to downstream downending, stacking, or palletized dispatch.<\/p>\n<p>Every transfer sequence is interlocked and automated. The coil is never manually lifted, pushed, or turned between initial entry and dispatch, eliminating mechanical edge damage and workplace strain. Because every module operates synchronously, the entire line throughput runs at the pace of its slowest station.<\/p>\n<p>Depending on line configuration, the packaging stations handle coil weights from 100 kg to 2,500 kg in standard horizontal formats, or 150 kg up to 6,500 kg on vertical packaging systems (with heavy-duty configurations accommodating 4,000 kg to 11,000 kg) [manufacturer rating]. The eye-through wrapping station supports slitted coils with widths of 20\u2013500 mm, outside diameters of \u00d8800\u20131,400 mm, and eye inside diameters of \u00d8508\u2013610 mm [manufacturer rating]. Conveyor roller speed is maintained at 12 m\/min, while the rotating ring delivers 8\u201380 r\/min variable speed, completing an eye-through wrap in 40\u201370 sec\/pcs [manufacturer rating]. For integrated mill systems utilizing automated turnstiles, walking beams, and coil cars, throughput achieves up to 60 coils per hour [manufacturer rating].<\/p>\n<h2 id=\"how-it-works\">Stations in an automated coil packaging line<\/h2>\n<table>\n<thead>\n<tr>\n<th>Station<\/th>\n<th>What it does<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Loading<\/td>\n<td>Takes the bare coil from the crane or coil car<\/td>\n<\/tr>\n<tr>\n<td>Eye-through wrapping<\/td>\n<td>Covers the coil through the eye and over the wall<\/td>\n<\/tr>\n<tr>\n<td>Handling and turning<\/td>\n<td>Moves or turns the coil between stations<\/td>\n<\/tr>\n<tr>\n<td>Strapping<\/td>\n<td>Adds radial and circumferential bands<\/td>\n<\/tr>\n<tr>\n<td>Discharge<\/td>\n<td>Hands the coil to stacking or dispatch<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Each station passes the coil to the next automatically, so the line runs at the pace of its slowest station.<\/p>\n<p>In our standard integration, the mechanical core comprises a mechanical upender\/tilter, an indexing coil transport station, and an orbital wrapping system driven by SEW Eurodrive gearmotors. The wrapping station accommodates multiple packaging media, including PE-coated crepe paper, stretch film, or woven PP tape (with roll specifications of ID 50 mm, OD 200\u2013500 mm, and width 100 mm) to defend coil surfaces against corrosion, condensation, and friction scuffs during transit.<\/p>\n<h2 id=\"straps\">Strap consumption per coil<\/h2>\n<p>Strap requirement is calculated directly from coil geometry and the specified binding pattern.

The strapping mechanism incorporates a 360\u00b0 rotating strapping head and arch system that indexes cleanly around the coil eye in both semi-automatic and fully automatic operating modes, with a heavy-duty strapping head engineered for a service life of up to 1,000,000 strapping cycles [manufacturer rating].<\/p>\n<p>For the strapping station on its own, see our <a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-steel-coil-strapping-machine\/\">automatic steel coil strapping machine<\/a>.

Keep people out of the guarded line while it runs, and enter only with the station stopped and isolated.<\/p>\n<p>Main control architecture centers on an industrial Siemens S7-1200 PLC linked to a multi-language touchscreen HMI. Main electrical power runs at 380 VAC (\u00b15%), 50 Hz, 3-phase 4-wire, with 220 VAC single-phase \/ 24 VDC control circuitry, supported by clean plant air supply at 5\u20138 kgf\/m\u00b2 [manufacturer rating].<\/p>\n<p>The standards that apply depend on the destination market. For CE markets under Machinery Directive 2006\/42\/EC, ISO 12100 sets the basic risk-assessment methodology and EN 415-10 sets specific safety requirements for automated packaging machines. Guarded enclosures are protected by safety light curtains, perimeter fencing, door interlocks, and emergency stop pushbuttons at the operator stations [manufacturer rating].<\/p>\n<h2 id=\"selection-checklist\">Selection checklist for an automated coil packaging line<\/h2>\n<ul>\n<li>Coil OD, ID, width and weight range.<\/li>\n<li>Coils per hour.<\/li>\n<li>Wrap material: paper, film or both.<\/li>\n<li>Radial and circumferential bands per coil.<\/li>\n<li>Eye position at dispatch.<\/li>\n<li>Building space, crane access and floor loading.<\/li>\n<\/ul>\n<h2 id=\"engineering-faq\">Engineering FAQ<\/h2>\n<p>Q: What stations does an automated coil packaging line have?\nA: Loading, eye-through wrapping, handling or turning, strapping and discharge.<\/p>\n<p>Q: How much strap does a coil take?\nA: About 23 m for 4 radial and 2 circumferential bands on a 1,500 mm OD, 508 mm ID, 1,200 mm wide coil in our illustrative example, before adding joint and seal overlap allowances.<\/p>\n<p>Q: What sets the line speed?\nA: The slowest station; buffers and indexing conveyor sections between stations keep the rest of the line moving smoothly without bottleneck starvation.<\/p>\n<p>Q: What wrap materials can the line run?\nA: Paper, stretch film, or woven PP tape on the wrapper, configured individually or in combination to suit project requirements.<\/p>\n<p>Q: How does coil delivery affect the line?\nA: Whether coils arrive by overhead crane C-hook, automated coil car, or roller conveyor determines the mechanical structure of the loading station.<\/p>\n<p>Q: Why start with a 3D layout?\nA: So the plant engineering team can check foundation boundaries, crane clearances, and logistics flow before any steel is cut or installed.<\/p>\n<p>Q: Do I need a turning station?\nA: Only if coils must leave eye vertical when they are wrapped eye horizontal, or the other way round. Upenders and downenders bridge the orientation gap between slitters and warehouse stacking.<\/p>\n<p>Q: How many radial bands can the strapping station apply automatically?\nA: The radial strapping head system can be programmed to index and apply 2, 3, 4, or 6 strapping bands automatically per coil.<\/p>\n<h2 id=\"next-step\">Next step<\/h2>\n<p>We plan your coil packaging line in three steps:<\/p>\n<ol>\n<li><strong>Submit your layout drawing<\/strong> with coil sizes, output and building layout to <strong>info@fhopepack.com<\/strong>.<\/li>\n<li><strong>Receive a proposal within 48 hours<\/strong>, with the station layout and strap plan.<\/li>\n<li><strong>Book a site survey<\/strong> to check the building space and crane access.<\/li>\n<\/ol>\n<h2 id=\"related-reading\">Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/Automatic-Coil-Packing-Line\/\">Automatic coil packing line<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/steel-coil-strapping-machinery\/\">Steel coil strapping machines<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/steel-coil-copper-coil-packaging-machine-for-eye-through-film-wrapping\/\">Video: steel coil, copper coil packaging machine for eye-through film wrapping<\/a><\/li>\n<\/ul>\n<h2 id=\"sources\">Sources<\/h2>\n<ul>\n<li>Machine content: FHOPE engineering team, 2026-10-04<\/li>\n<li>Strap example: our worked example, illustrative values<\/li>\n<li>Machine in action: <a href=\"https:\/\/www.youtube.com\/watch?v=C9rw7txhrl8\">our video on YouTube<\/a><\/li>\n<li>Standards scope: <a href=\"https:\/\/www.iso.org\/standard\/51528.html\">ISO 12100:2010<\/a>, <a href=\"https:\/\/www.nen.nl\/en\/nen-en-415-10-2014-en-191845\">EN 415-10:2014<\/a><\/li>\n<li>Equipment engineering specification: <a href=\"https:\/\/www.fhopepack.com\/Steel-coil-wrapping-machine\/Horizontal-steel-coil-packing-machine-FPCA-1200.html\">FPCA-1200 Horizontal Steel Coil Packing Machine<\/a><\/li>\n<li>Strapping unit technical data: <a href=\"https:\/\/www.fhopepack.com\/steel-coil-strapping-machinery\/Radial-steel-coil-strapping-machine.html\">Radial Steel Coil Strapping Machine<\/a><\/li>\n<li>Line system integration: <a href=\"https:\/\/www.fhopepack.com\/Automatic-Coil-Packing-Line\/Vertical-coil-packaging-line.html\">Vertical Coil Packaging Line<\/a><\/li>\n<\/ul>\n<p><strong>Last reviewed:<\/strong> 2026-10-28<\/p>","protected":false},"excerpt":{"rendered":"<p>Executive summary An automated coil packaging line takes a bare coil from the slitter or mill and discharges it wrapped, strapped and ready to ship, with no manual handling in between.
