An inclined roller conveyor tilts a coil up and lays it flat on a rotating platform on the roller line.<\/p>\n<p>Clear stretch film goes round the turning coil on the first pass. The wrapping unit then comes down again for a second pass. The wrapped coil runs on to an outfeed section, where an overhead arm lifts it onto a stack of wrapped coils on a wooden pallet.<\/p>\n<h2 id=\"how-it-works\">How the two-stage line works<\/h2>\n<table>\n<thead>\n<tr>\n<th>Step<\/th>\n<th>What happens<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Load<\/td>\n<td>Coils wait on spindles at the handling station<\/td>\n<\/tr>\n<tr>\n<td>Lay flat<\/td>\n<td>The inclined conveyor turns the coil onto the platform<\/td>\n<\/tr>\n<tr>\n<td>First wrap<\/td>\n<td>Film goes round the coil while it turns<\/td>\n<\/tr>\n<tr>\n<td>Second wrap<\/td>\n<td>The unit comes down again for a second pass<\/td>\n<\/tr>\n<tr>\n<td>Stack<\/td>\n<td>An overhead arm sets the coil on the pallet stack<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>A second pass doubles the film cover while the coil stays on the same platform.<\/p>\n<h2 id=\"layers\">Film layer and overlap calculation<\/h2>\n<p>We count passes at the OD, where overlap is lowest.

Keep people outside the guarded zones while the line runs, and enter only with it stopped.<\/p>\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 sets general requirements for packaging machines.<\/p>\n<h2 id=\"selection-checklist\">Selection checklist for a coil wrapping and stacking line<\/h2>\n<ul>\n<li>Coil OD, ID, width and weight range.<\/li>\n<li>Coil material and surface finish.<\/li>\n<li>Film layers needed for your transport.<\/li>\n<li>Coils per hour.<\/li>\n<li>Stack height and pallet size.<\/li>\n<li>Floor space and line layout.<\/li>\n<\/ul>\n<h2 id=\"engineering-faq\">Engineering FAQ<\/h2>\n<p>Q: Why wrap in two stages?\nA: Each stage lays two layers at 50% overlap, so two stages give 4 layers at the OD without slowing the line.<\/p>\n<p>Q: Where on the coil is overlap counted?\nA: At the OD, where film overlap is lowest.<\/p>\n<p>Q: How many passes does a coil need?\nA: About 63 per stage for a 1,000 mm OD coil with 100 mm film at 50% overlap in our example.<\/p>\n<p>Q: How are the coils turned flat?\nA: An inclined roller conveyor lays each coil onto the rotating platform.<\/p>\n<p>Q: How high is a stack?\nA: We set it from your forklift, rack and truck limits; 1,200 mm for three 400 mm wide coils in our example.<\/p>\n<p>Q: Is the line guarded?\nA: Yes.
