The mechanical wrapping cycle proceeds in four discrete phases:<\/p>\n<ol>\n<li><strong>Load:<\/strong> The operator places the tied coil on the table, centering it around the lower aperture of the rotating ring.<\/li>\n<li><strong>Clamp:<\/strong> Guide rollers centre the coil and a press rod holds it from above.<\/li>\n<li><strong>Wrap:<\/strong> The orbital ring carries the packaging film dispenser through the coil eye. Simultaneously, the base drive wheels rotate the coil so that each consecutive wrap overlaps the preceding layer at a uniform pitch.<\/li>\n<li><strong>Finish:<\/strong> Once the coil completes a 360\u00b0 rotation, the film is severed, the top press clamp retracts, and the wrapped coil is unloaded.<\/li>\n<\/ol>\n<p>The overlap ratio is set by the ratio of ring speed to coil turning speed. Inverters let you change either from the panel. Film tension is set on the ring: our standard configuration incorporates a 2.5 kg\u00b7m magnetic powder tension controller, so light or soft coils can be wrapped without crushing them. Press-rod force and automatic cut-and-clamp options are confirmed at quote.<\/p>\n<h2 id=\"models\">Choosing a model by coil size<\/h2>\n<p>Selecting the correct wrapper requires matching the physical dimensions and mass of your coil envelope against machine clearance limits. The primary mechanical constraint is the minimum internal diameter: the orbital ring cross-section and film carriage must pass through the coil eye without interference.<\/p>\n<table>\n<thead>\n<tr>\n<th style=\"text-align: left\">Item<\/th>\n<th style=\"text-align: left\">FPCA100<\/th>\n<th style=\"text-align: left\">FPCA-200<\/th>\n<th style=\"text-align: left\">FPCA-300<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"text-align: left\">Coil ID<\/td>\n<td style=\"text-align: left\">90\u2013250 mm<\/td>\n<td style=\"text-align: left\">150\u2013400 mm<\/td>\n<td style=\"text-align: left\">250\u2013510 mm<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Coil OD<\/td>\n<td style=\"text-align: left\">150\u2013400 mm<\/td>\n<td style=\"text-align: left\">250\u2013500 mm<\/td>\n<td style=\"text-align: left\">400\u2013900 mm<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Coil width<\/td>\n<td style=\"text-align: left\">50\u2013180 mm<\/td>\n<td style=\"text-align: left\">80\u2013200 mm<\/td>\n<td style=\"text-align: left\">60\u2013300 mm<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Coil weight<\/td>\n<td style=\"text-align: left\">2\u201330 kg<\/td>\n<td style=\"text-align: left\">2\u201350 kg<\/td>\n<td style=\"text-align: left\">20\u2013200 kg<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Ring speed<\/td>\n<td style=\"text-align: left\">10\u2013120 r\/min<\/td>\n<td style=\"text-align: left\">10\u2013120 r\/min<\/td>\n<td style=\"text-align: left\">10\u201390 r\/min<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Cycle<\/td>\n<td style=\"text-align: left\">18\u201330 s<\/td>\n<td style=\"text-align: left\">20\u201330 s<\/td>\n<td style=\"text-align: left\">20\u201338 s<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Overlap<\/td>\n<td style=\"text-align: left\">20\u201390%<\/td>\n<td style=\"text-align: left\">20\u201380%<\/td>\n<td style=\"text-align: left\">10\u201390%<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Power<\/td>\n<td style=\"text-align: left\">1.8 kW<\/td>\n<td style=\"text-align: left\">2.0 kW<\/td>\n<td style=\"text-align: left\">2.4 kW<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Wrap material<\/td>\n<td style=\"text-align: left\">PE, stretch film, PVC<\/td>\n<td style=\"text-align: left\">PE, stretch film, PVC<\/td>\n<td style=\"text-align: left\">LLDPE, PVC, PE, paper<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><em>Note: All specification parameters represent manufacturer baseline ratings [manufacturer rating].
