Wrapping each coil on its own, before stacking, has clear benefits:<\/p>\n<ul>\n<li><strong>Every coil is sealed through the eye<\/strong>, so it can later be split from the stack without opening the package.<\/li>\n<li><strong>The ring only needs to fit one coil width<\/strong>, not the full stack height.<\/li>\n<li><strong>Film protects the faces<\/strong> where one coil sits on the next in the stack.<\/li>\n<\/ul>\n<p>Our coil packing line programs adjust centring, tension and overlap per coil type, so a thin coil and a wide coil get the same film coverage.<\/p>\n<h2 id=\"gantry-stacker\">How the gantry stacker builds the stack<\/h2>\n<p>The stacker is a gantry over the conveyor with a carriage that moves up and down.<\/p>\n<ol>\n<li>A wrapped coil stops under the gantry.<\/li>\n<li>The gripper arms close on the outer edge of the coil.<\/li>\n<li>The carriage lifts, and the coil is set down on the stack being built.<\/li>\n<li>When the stack is complete, the rollers carry it to the outfeed.<\/li>\n<\/ol>\n<p>On our automatic coil packing line, the quote form allows up to 6 coils per stack. In this layout the coils are stacked eye to sky. Eye-to-wall packing is also offered, with a different handling station from this gantry; see <a href=\"https:\/\/www.fhopepack.com\/videos\/buyers-guide-integrating-automated-stretch-wrapping-and-downender-stacking-systems-for-heavy-steel-coils\/\">stretch wrapping and downender stacking<\/a>. Stack height is chosen with your handling: a forklift, a C-hook or a pallet.<\/p>\n<h2 id=\"coil-range\">Coil range for conveyor-fed wrapping<\/h2>\n<p>From our steel coil wrapper model table, the conveyor-loaded models:<\/p>\n<table>\n<thead>\n<tr>\n<th>Model<\/th>\n<th>Coil ID<\/th>\n<th>Coil OD<\/th>\n<th>Coil Width<\/th>\n<th>Max Coil Weight<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>FPCA-1000<\/strong><\/td>\n<td>508 \/ 610 mm<\/td>\n<td>700\u20131600 mm<\/td>\n<td>20\u2013400 mm<\/td>\n<td>2000 kg<\/td>\n<\/tr>\n<tr>\n<td><strong>FPCA-1200<\/strong><\/td>\n<td>508\u2013610 mm<\/td>\n<td>800\u20131400 mm<\/td>\n<td>20\u2013500 mm<\/td>\n<td>2500 kg<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Wider slit-line engineering can cover slit widths from 8 mm up, coil IDs of 300\/508\/610 mm, and single-coil weights to 4,000 kg at 20\u201340 coils per hour [manufacturer rating].

For CE markets, ISO 12100 sets the risk-assessment method and EN 415-10 covers general requirements for packaging machines, which fixes guarding and the emergency-stop arrangement.<\/p>\n<p>The line runs on a PLC with HMI. Guarding around the ring and under the gantry stacker is set in the risk assessment for each layout.<\/p>\n<h2 id=\"engineering-faq\">Engineering FAQ<\/h2>\n<p>Q: How does the gantry stacker move a coil onto the stack?\nA: Vertical gripper arms close on the outer edge of the coil, the carriage lifts, and the coil is set down on the stack on the conveyor.<\/p>\n<p>Q: How many coils can go in one stack?\nA: Our automatic coil packing line quote form allows up to 6 coils per stack, depending on coil weight and handling.<\/p>\n<p>Q: Which coil widths suit conveyor-fed wrapping?\nA: Our FPCA-1000 covers 20\u2013400 mm and the FPCA-1200 covers 20\u2013500 mm; wider slit-line engineering starts from 8 mm [manufacturer rating].<\/p>\n<p>Q: Can the stack be strapped after stacking?\nA: Yes. PET or steel strapping is an option on our coil packing lines, added as a station after the stacker.<\/p>\n<p>Q: Is film the only wrap option?\nA: No. Film, paper and woven wrap are all options, set by the program for each coil type.<\/p>\n<h2 id=\"next-step\">Next step<\/h2>\n<p>We size a wrap-and-stack line in three steps:<\/p>\n<ol>\n<li><strong>Submit your layout drawing<\/strong> with the coil range, coils per hour and stack pattern, to <strong>info@fhopepack.com<\/strong>.<\/li>\n<li><strong>Receive a proposal within 48 hours<\/strong>, with the wrapper, stacker and conveyor layout.<\/li>\n<li><strong>Book a site survey<\/strong> so we confirm the slitter exit, floor space and the stack outfeed.<\/li>\n<\/ol>\n<h2 id=\"related-reading\">Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/automated-slit-coil-packing-line-for-service-center-boost-your-productivity\/\">Slit Coil Packing Line for Service Centers: Strapping, Eye-Through Wrapping and Stacking<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/5-critical-roi-metrics-to-evaluate-a-full-steel-coil-packaging-line-from-strapping-to-stacking-automation\/\">Steel Coil Packaging Line from Strapping to Stacking: Five ROI Metrics and a Payback Formula<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/master-coil-packing-machine-with-corner-protector\/\">Master Coil Eye-Through Wrapper in a Fenced Cell<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/Automatic-Coil-Packing-Line\/\">Automatic coil packing line<\/a><\/li>\n<\/ul>\n<h2 id=\"sources\">Sources<\/h2>\n<ul>\n<li>Machine in action: <a href=\"https:\/\/www.youtube.com\/watch?v=vf5bjc89GVc\">the video on YouTube<\/a><\/li>\n<li>Up to 6 coils per stack, eye to sky \/ eye to wall, PET or steel strap, film\/paper\/woven wrap, PLC\/HMI settings: <a href=\"https:\/\/www.fhopepack.com\/Automatic-Coil-Packing-Line\/\">Automatic coil packing line<\/a><\/li>\n<li>FPCA-1000 and FPCA-1200 values: <a href=\"https:\/\/www.fhopepack.com\/Steel-coil-wrapping-machine\/\">Steel coil wrapping machine<\/a><\/li>\n<li>Standards scope: ISO 12100:2010; <a href=\"https:\/\/www.nen.nl\/en\/nen-en-415-10-2014-en-191845\">EN 415-10:2014<\/a><\/li>\n<li>Proposal timing: approved house CTA (proposal within 48 hours)<\/li>\n<\/ul>\n<p><strong>Last reviewed:<\/strong> 2026-10-29<\/p>","protected":false},"excerpt":{"rendered":"<p>Executive summary Narrow steel coils lie flat on a roller conveyor.
