Slit coils from the slitter are held on a multi-arm turnstile, and a down-ender picks individual coils and tilts them 90 degrees to the eye-vertical position. The line then integrates coil down-ending, PET strapping, orbital through-the-eye wrapping, and automated stacking [manufacturer rating].<\/p>\n<p>After tilting, driven conveyors index each flat-lying coil into the strapping and wrapping cells. The orbital wrapper feeds stretch film, paper, or VCI anti-corrosion film through the internal eye and over the outer circumference. The wrapped coil then indexes to a weighing, labeling, and stacking station, where coils are stacked onto pallets ready for forklift transport.<\/p>\n<h2 id=\"vertical\">Why pack eye-vertical<\/h2>\n<ul>\n<li><strong>Stable.<\/strong> A flat coil cannot roll.<\/li>\n<li><strong>Stackable.<\/strong> Narrow coils stack several high.<\/li>\n<li><strong>Compact.<\/strong> Eye-vertical coils take less floor space.<\/li>\n<li><strong>Pallet ready.<\/strong> Stacks sit straight on pallets.<\/li>\n<\/ul>\n<p>Slit steel coils have narrow strip widths relative to their outside diameters, so they are unstable when resting eye-horizontal and can roll under momentum. In the eye-vertical position the coil rests on its broad flat side face, which gives natural stability, moisture protection, and secure handling through the warehouse [manufacturer rating].<\/p>\n<p>For coils with outside diameters between 300 mm and 500 mm and unit weights between 250 kg and 350 kg, eye-vertical placement allows clean application of high-tension PET strapping combined with moisture-resistant through-the-eye wrapping [manufacturer rating].<\/p>\n<h2 id=\"pace\">Line pace<\/h2>\n<p><strong>Worked example (illustrative).<\/strong><\/p>\n<table>\n<thead>\n<tr>\n<th>Item<\/th>\n<th>Value<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Coils per slitting cut (illustrative)<\/td>\n<td>12<\/td>\n<\/tr>\n<tr>\n<td>Cuts per hour (illustrative)<\/td>\n<td>5<\/td>\n<\/tr>\n<tr>\n<td>Coils per hour, 12 \u00d7 5<\/td>\n<td>60<\/td>\n<\/tr>\n<tr>\n<td>Time per coil, 3,600 \u00f7 60<\/td>\n<td>60 s<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The 60-second takt time is the target average across all inline stations.

In the worked example the takt is 60 s per coil, with buffers between stations. Standard automated narrow coil lines deliver 20\u201340 coils\/hr [manufacturer rating].<\/p>\n<p>Q: Can strapping be added?\nA: Yes, before wrapping. A radial PET or steel strapping station is integrated after the down-ender.<\/p>\n<p>Q: Does it take a whole cut?\nA: Yes.
