A motorised trolley carries the coil in and out, so the operator does not lift it. The FPW-500 takes coils up to 1,500 kg and the FPW-800 up to 3,000 kg. A worked example shows why the coil bore always gets more overlap than the outside.<\/p>\n<\/blockquote>\n<iframe loading=\"lazy\" width=\"940\" height=\"535\" src=\"https:\/\/www.youtube.com\/embed\/FkB2erBpDHo\" 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=\"#why\">Why steel wire coils are wrapped through the eye<\/a><\/li>\n<li><a href=\"#build\">How our trolley-loaded wire coil wrapper works<\/a><\/li>\n<li><a href=\"#specs\">FPW-500 and FPW-800 specifications<\/a><\/li>\n<li><a href=\"#example\">Worked example: ring passes and overlap at the bore<\/a><\/li>\n<li><a href=\"#materials\">Choosing the packing material<\/a><\/li>\n<li><a href=\"#inline\">Trolley type or inline conveyor type<\/a><\/li>\n<li><a href=\"#selection-checklist\">Selection checklist: what to send us<\/a><\/li>\n<li><a href=\"#safety\">Safety and EN 415-10<\/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=\"why\">Why steel wire coils are wrapped through the eye<\/h2>\n<p>Drawn steel wire, PC wire and spring wire rust quickly once moisture reaches the turns. A coil that only has straps or an outer cover stays open at the bore and the faces. Sea freight makes this worse, because the coil sits for weeks in damp air.<\/p>\n<p>Eye-through wrapping closes the coil completely. Each pass of the film goes through the bore, over one face, round the outside and back over the other face. As the coil turns, the passes build into a full cover over every surface.<\/p>\n<h2 id=\"build\">How our trolley-loaded wire coil wrapper works<\/h2>\n<p>The coil stands on its edge in a cradle of supporting rollers mounted on a motorised trolley. The trolley runs the coil into the wrapping position, centred on the ring, and takes it out again after wrapping.<\/p>\n<ul>\n<li><strong>Wrapping ring.<\/strong> A ring carrying the film roll turns through the coil bore, laying film over the bore, both faces and the outside on every turn.<\/li>\n<li><strong>Coil rotation.<\/strong> Polyurethane-covered rollers turn the coil slowly, so each film pass lands beside the last one.<\/li>\n<li><strong>Main board height.<\/strong> A geared motor raises or lowers the main board to centre coils of different diameters on the ring.<\/li>\n<li><strong>Mechanical hand.<\/strong> In automatic mode it feeds the film at the start and cuts it at the end, so no one reaches into the ring. The FPW-800 also offers a semi-automatic mode for plants that want the operator to start and finish each wrap.<\/li>\n<li><strong>Controls.<\/strong> A Siemens PLC and HMI run the cycle. Overlap and film tension are set on the panel.<\/li>\n<\/ul>\n<p>Strap the coil before it reaches the wrapper. Our wire coiling and strapping machines strap each coil through the eye at 2\u20134 places, which holds the turns while the coil rolls on the cradle. The PU-coated contact points keep the wire surface free of scratches. An antiskid mould structure holds the coil steady while the ring turns.<\/p>\n<h2 id=\"specs\">FPW-500 and FPW-800 specifications<\/h2>\n<table>\n<thead>\n<tr>\n<th style=\"text-align: left\">Item<\/th>\n<th style=\"text-align: left\">FPW-500<\/th>\n<th style=\"text-align: left\">FPW-800<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"text-align: left\">Coil ID<\/td>\n<td style=\"text-align: left\">300\u2013700 mm<\/td>\n<td style=\"text-align: left\">over 500 mm<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Coil OD<\/td>\n<td style=\"text-align: left\">700\u20131,300 mm<\/td>\n<td style=\"text-align: left\">800\u20131,400 mm<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Coil width<\/td>\n<td style=\"text-align: left\">50\u2013500 mm<\/td>\n<td style=\"text-align: left\">300\u2013800 mm<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Coil weight<\/td>\n<td style=\"text-align: left\">40\u20131,500 kg<\/td>\n<td style=\"text-align: left\">200\u20133,000 kg<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Overlap<\/td>\n<td style=\"text-align: left\">10%\u201390%, adjustable<\/td>\n<td style=\"text-align: left\">10%\u201390%, adjustable<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Film roll<\/td>\n<td style=\"text-align: left\">ID 50 mm, OD 100\u2013450 mm, width 100\u2013120 mm<\/td>\n<td style=\"text-align: left\">ID 50 mm, OD 100\u2013250 mm, width 100\u2013300 mm<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Materials<\/td>\n<td style=\"text-align: left\">PVC, LDPE, LLDPE, paper, HDPE<\/td>\n<td style=\"text-align: left\">PVC, LLDPE, PE, paper, HDPE<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Power<\/td>\n<td style=\"text-align: left\">3.5 kW<\/td>\n<td style=\"text-align: left\">3.4 kW<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Supply<\/td>\n<td style=\"text-align: left\">380 V, 50 Hz, 3 phase<\/td>\n<td style=\"text-align: left\">380 V, 50 Hz, 3 phase<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Air supply<\/td>\n<td style=\"text-align: left\">4\u20136 kgf\/cm\u00b2<\/td>\n<td style=\"text-align: left\">4\u20136 kgf\/cm\u00b2, confirmed per order<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The FPW-800 runs in fully automatic or semi-automatic mode and is built for pre-stranded and PC wire coils. Its ring centre height is adjustable.<\/p>\n<h2 id=\"example\">Worked example: ring passes and overlap at the bore<\/h2>\n<p>Take a coil of 1,200 mm OD, 500 mm ID and 400 mm width. That sits inside the FPW-500 range. Your own coil figures go in the same way.<\/p>\n<p><strong>Passes for the outside.<\/strong> Use 100 mm film at 50% overlap measured on the OD. Each pass then advances 100 \u00d7 (1 \u2212 0.5) = 50 mm round the outside.<\/p>\n<ul>\n<li>OD circumference: \u03c0 \u00d7 1,200 = 3,770 mm<\/li>\n<li>Ring passes: 3,770 \u00f7 50 = 75.4, so 76 passes<\/li>\n<\/ul>\n<p><strong>Overlap at the bore.<\/strong> The same 76 passes must fit round a much smaller circle inside. The advance there is 50 \u00d7 500 \u00f7 1,200 = 20.8 mm per pass. The overlap at the bore is 1 \u2212 20.8 \u00f7 100 = 79%.<\/p>\n<p>So the bore always carries more layers than the outside. Set overlap for the OD you need, and the bore takes care of itself. Raising OD overlap to 70% would push the bore near 88% and waste film there.<\/p>\n<p><strong>Film per pass.<\/strong> One pass follows the coil section: 2 \u00d7 (400 + 350) = 1,500 mm, where 350 mm is (OD \u2212 ID) \u00f7 2. Seventy-six passes use about 114 m of film before stretch.<\/p>\n<p><strong>Cycle time.<\/strong> Wrapping time = passes \u00f7 ring speed in r\/min. We confirm the ring speed for your coil and film when we quote.<\/p>\n<h2 id=\"materials\">Choosing the packing material<\/h2>\n<p>Stretch film and PE film give a clear, moisture-tight cover. Crepe paper, compound paper and non-woven fabric let the coil breathe and suit oiled wire. Woven belts and HDPE tape add tear strength for rough handling. Many wire plants wrap paper first and film second for export coils.<\/p>\n<h2 id=\"inline\">Trolley type or inline conveyor type<\/h2>\n<p>Our FPW-500 and FPW-800 load by trolley and suit a packing station fed by crane or forklift.

The turning ring and the trolley are the main hazards. Mesh guarding encloses the ring head, and the mechanical hand keeps hands out of the film path. We add perimeter fencing with interlocked access gates to suit your floor layout. Emergency stops sit on the control panel.<\/p>\n<h2 id=\"engineering-faq\">Engineering FAQ<\/h2>\n<p>Q: Why does the bore get more overlap than the outside?\nA: Every pass goes through the bore, and the bore circle is smaller. The same passes crowd closer together there.<\/p>\n<p>Q: Can one machine wrap several coil sizes?\nA: Yes, within the model range. The main board height and roller spacing are adjusted for each size.<\/p>\n<p>Q: Will the rollers mark the wire?\nA: The contact rollers are PU-covered to protect the wire surface.<\/p>\n<p>Q: Which safety standards apply?\nA: ISO 12100 for the risk assessment and EN 415-10 for the machine, in CE markets.<\/p>\n<h2 id=\"next-step\">Next step<\/h2>\n<ol>\n<li><strong>Email your coil sizes, weights and coils per shift<\/strong> to <strong>info@fhopepack.com<\/strong>.<\/li>\n<li><strong>We reply within 24 hours with a proposal<\/strong> naming the model and material.<\/li>\n<li><strong>We send a layout drawing<\/strong> for the trolley path and crane access.<\/li>\n<\/ol>\n<h2 id=\"related-reading\">Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/Wire-coil-wrapping-machine\/Wire-coil-wrapping-machine-FPW-500.html\">FPW-500 wire coil wrapping machine<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/Wire-coil-wrapping-machine\/Wire-coil-wrapping-machine-FPW-800.html\">FPW-800 steel wire wrapping machine<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/how-to-choose-the-coil-wrapping-machine-per-your-steel-wire-coil\/\">How to choose the coil wrapping machine per your steel wire coil<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/how-to-choose-packing-material-bombination-for-the-steel-wire-packing\/\">How to choose packing material combination for steel wire packing<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/wire-coil-wrapping-machine-2\/\">Wire coil wrapping machine for wire packing with paper<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/steel-wire-coil-wrapping-machine-and-packing-machine-2\/\">Steel wire coil wrapping machine and packing machine<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/how-to-packing-the-steel-wire-for-sea-shipping\/\">How to pack steel wire for sea shipping<\/a><\/li>\n<\/ul>\n<h2 id=\"sources\">Sources<\/h2>\n<ul>\n<li>Specifications: FHOPE FPW-500, FPW-800 and FPW-AU300 product pages<\/li>\n<li>Machine video: <a href=\"https:\/\/www.youtube.com\/watch?v=FkB2erBpDHo\">steel wire coil wrapping on YouTube<\/a><\/li>\n<li>Overlap and film use: our worked example, illustrative coil figures<\/li>\n<li>Standards: EN 415-10 (packaging machines, general safety); ISO 12100:2010<\/li>\n<\/ul>\n<p><strong>Last reviewed:<\/strong> 2026-10-17<\/p>","protected":false},"excerpt":{"rendered":"<p>Executive summary Our FPW wire coil wrapping machine seals a steel wire coil in film or paper by passing a turning ring through the coil eye while the coil rolls on its supports.
