We judge a line like this on four numbers you can measure yourself: seconds per coil at the slowest station, first-pass label reads, stack quality and film use per coil. Each one has a simple formula, shown below.<\/p>\n<\/blockquote>\n<iframe loading=\"lazy\" width=\"1053\" height=\"592\" src=\"https:\/\/www.youtube.com\/embed\/aihySbLbCN4\" title=\"Automatic Steel Coil Strapping, Labeling and Stacking Line\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe>\n<h2 id=\"table-of-contents\">Table of Contents<\/h2>\n<ul>\n<li><a href=\"#video\">What the clip shows<\/a><\/li>\n<li><a href=\"#kpi-cycle\">KPI 1: seconds per coil at the slowest station<\/a><\/li>\n<li><a href=\"#kpi-label\">KPI 2: first-pass label reads<\/a><\/li>\n<li><a href=\"#kpi-stack\">KPI 3: stack quality at the gantry stacker<\/a><\/li>\n<li><a href=\"#kpi-film\">KPI 4: film use per coil<\/a><\/li>\n<li><a href=\"#selection-checklist\">Selection checklist for a coil labelling and stacking line<\/a><\/li>\n<li><a href=\"#safety\">Controls and 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<h2 id=\"video\">What the clip shows<\/h2>\n<p>The clip is about 50 s long and has three scenes. The times are read from the recording.<\/p>\n<table>\n<thead>\n<tr>\n<th>Clip time<\/th>\n<th>Station<\/th>\n<th>What happens<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>0\u201318 s<\/td>\n<td>Top-face head station<\/td>\n<td>Coils lie eye-to-sky on a yellow roller table.

Coils move between stations on rollers or in the gripper.<\/p>\n<p>The four KPIs below are how you check a line like this on your own floor.<\/p>\n<h2 id=\"kpi-cycle\">KPI 1: seconds per coil at the slowest station<\/h2>\n<p>A coil line runs at the pace of its slowest station. Labelling, stacking and wrapping each have their own cycle; the longest one sets output.<\/p>\n<p>Coils per hour = 3600 \u00f7 seconds per coil at the slowest station.<\/p>\n<p>Measure each station separately with the line running real coils, not a demo. Then compare the result with your slitter output. If the slitter makes coils faster than the slowest packing station can take them, coils queue and the line operator starts making manual decisions.<\/p>\n<p>On our proposals we list a cycle per station, so you can see which one is the limit. A buffer conveyor ahead of the slowest station absorbs short stops but does not raise average output.<\/p>\n<h2 id=\"kpi-label\">KPI 2: first-pass label reads<\/h2>\n<p>A label is only useful if the warehouse scanner reads it the first time.<\/p>\n<p>First-pass read rate = labels read at first scan \u00f7 labels applied.<\/p>\n<p>Three things move this number:<\/p>\n<ul>\n<li><strong>Label position.<\/strong> A fixed label head puts the label in the same place on every coil, so a scanner or forklift driver finds it.<\/li>\n<li><strong>Label data.<\/strong> Our coil lines can take coil data from ERP or MES, so the label matches the coil record without retyping.<\/li>\n<li><strong>Surface.<\/strong> The head needs a clean, flat area on the face. We place the labelling station where the coil face is still accessible, before film covers it, or we label the film, depending on your logistics.<\/li>\n<\/ul>\n<p>Track rejected or re-printed labels per shift. A rising count points to position drift or a print-head issue long before customers complain.<\/p>\n<h2 id=\"kpi-stack\">KPI 3: stack quality at the gantry stacker<\/h2>\n<p>The gantry stacker in the clip builds a stack of coils on a pallet. Two checks tell you whether stacking is right.<\/p>\n<ul>\n<li><strong>Centring error:<\/strong> how far each coil sits off the stack axis. An offset stack leans and loads one side of the pallet.<\/li>\n<li><strong>Re-stack count:<\/strong> stacks an operator had to straighten or rebuild by hand, per shift.<\/li>\n<\/ul>\n<p>Stacks per hour = coils per hour \u00f7 coils per stack.<\/p>\n<p>Our coil line quote form allows stacks of up to 6 coils. Your working height comes from coil weight, coil width, the pallet and forklift capacity. We set it with you at layout stage.<\/p>\n<h2 id=\"kpi-film\">KPI 4: film use per coil<\/h2>\n<p>Film is a running cost, so measure it per coil, not per month.<\/p>\n<p>Film mass per coil (g) = film length used (m) \u00d7 film width (mm) \u00d7 thickness (\u00b5m) \u00d7 density (g\/cm\u00b3) \u00f7 1000. Keep the units exactly as written and the factor of 1000 does the conversion.<\/p>\n<p>Weigh a full film roll, wrap a known number of coils, weigh the roll again, and divide. Do this for each coil size you run. If film use per coil drifts up with no change in coil size, check the tension and overlap settings first.<\/p>\n<p>Our coil line programs store tension and overlap per coil specification, so a size change does not depend on the operator re-tuning by hand.<\/p>\n<h2 id=\"selection-checklist\">Selection checklist for a coil labelling and stacking line<\/h2>\n<ul>\n<li>Coil OD, ID, width and weight range, and the heaviest coil on the order.<\/li>\n<li>Label content, label position (face or film) and the data source: ERP, MES or manual.<\/li>\n<li>Strapping before stacking: PET or steel strap, and how many straps (see our <a href=\"https:\/\/www.fhopepack.com\/videos\/in-depth-engineering-evaluation-optimizing-tilting-dynamics-strapping-tension-and-film-stretch-ratios-for-ultra-thin-slit-coils\/\">slit coil strapping and wrapping line<\/a>).<\/li>\n<li>Wrap material: stretch film, paper or woven, and the overlap you specify.<\/li>\n<li>Stack height, pallet type and forklift access to the outfeed.<\/li>\n<li>Final package direction: eye-to-sky or eye-to-wall.<\/li>\n<li>Target coils per hour from your slitter, and the station you expect to limit it.<\/li>\n<\/ul>\n<h2 id=\"safety\">Controls and safety<\/h2>\n<p>The standards that apply depend on the destination market. 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 head stations, the gantry gripper and the overhead arm are the moving hazards. The stacker zone is fenced; label and film changes are done with the station stopped.<\/p>\n<h2 id=\"engineering-faq\">Engineering FAQ<\/h2>\n<p>Q: Which KPI should we track first on a new coil packing line?\nA: Seconds per coil at the slowest station. It sets coils per hour (3600 \u00f7 that time) and tells you where a buffer or a second machine would pay back.<\/p>\n<p>Q: How do we measure first-pass label reads?\nA: Divide labels read at the first scan by labels applied, per shift. Re-prints and manual entries count as misses.<\/p>\n<p>Q: Can labels be applied after wrapping?\nA: Yes. We either label the coil face before the film goes on or label the film itself. The choice depends on where your warehouse scans the coil.<\/p>\n<p>Q: What should we inspect first if film use per coil goes up?\nA: If film use rises with no change in coil size, check the tension and overlap settings in the coil program first. Measure it by weighing the roll before and after a counted batch.<\/p>\n<p>Q: How high can the gantry stack coils?\nA: Our quote form takes up to 6 coils per stack. The working height depends on coil weight, width, pallet and forklift.<\/p>\n<h2 id=\"next-step\">Next step<\/h2>\n<p>We size a coil strapping, labelling and stacking line in three steps:<\/p>\n<ol>\n<li><strong>Submit your layout drawing<\/strong> with the coil OD, ID, width, weight, label content and output target, to <strong>info@fhopepack.com<\/strong>.<\/li>\n<li><strong>Receive a proposal within 48 hours<\/strong>, with a cycle per station so you can see the limiting station.<\/li>\n<li><strong>Book a site survey<\/strong> so we confirm the slitter exit, the line direction and forklift access to the stacks.<\/li>\n<\/ol>\n<h2 id=\"related-reading\">Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-copper-strip-coil-packing-line-with-labeling-wrapping-stacking-system\/\">Automatic Copper Strip Coil Packing Line with Labeling, Wrapping and Stacking<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/coil-wrapping-machine-with-tapping-and-barcode-printer\/\">Coil Wrapping Machine with Taping and Barcode Label Printer<\/a><\/li>\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<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/continuous-downtime-inconsistent-tension-or-manual-bottlenecks-what-is-the-primary-failure-point-in-your-stainless-steel-coil-packaging-line\/\">Stainless Steel Coil Packaging Line: Tilting, Eye-Through Wrapping, Labelling and Stacking<\/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>Station sequence and clip times: <a href=\"https:\/\/www.youtube.com\/watch?v=aihySbLbCN4\">the video on YouTube<\/a> (about 50 s; @Fhopepack)<\/li>\n<li>Line family, ERP\/MES labelling, programs, stacking height on the quote form, strapping and wrap options: <a href=\"https:\/\/www.fhopepack.com\/Automatic-Coil-Packing-Line\/\">Automatic Coil Packing Line<\/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> 2026-10-06<\/p>","protected":false},"excerpt":{"rendered":"<p>Executive summary In this clip of about 50 s, slit coils pass a top-face head station, a gantry stacker builds them onto a pallet, and a second line shows an overhead-arm station run from its [&hellip;]<\/p>","protected":false},"author":4,"featured_media":15321,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_seopress_titles_title":"Steel Coil Labelling & Stacking: 4 Line KPIs","_seopress_titles_desc":"Our steel coil line handles, labels and gantry-stacks slit coils.
