A <strong>FPW-300 eye-through orbital coil wrapping machine<\/strong> automates the entire line from coiling and strapping to wrap coating and stacking. The system winds wire into coils, applies strapping bands, then feeds each coil through an orbital eye-through wrapper that applies stretch film or paper packaging around the coil&#8217;s cross-section before stacking for dispatch. This integrated approach eliminates manual wrapping, ensures uniform protection, and achieves cycle times measured in seconds per coil.<\/p>\n<iframe loading=\"lazy\" width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/e09BXaC1EJA\" frameborder=\"0\" allowfullscreen><\/iframe>\n<h2>Executive Summary<\/h2>\n<p>This machine class is one option within the broader family of coil packing machines. Depending on coil geometry, throughput, and line integration, alternatives include turntable-style and horizontal ring systems. The eye-through orbital design is specifically suited for narrow, eye-through wire coils where spinning a loose coil on a turntable could cause layer slippage.<\/p>\n<h2>Working Principle<\/h2>\n<p>The FPW-300 line operates in a continuous sequence:<\/p>\n<ol>\n<li>1. <strong>Wire coiling.<\/strong> The uncoiled wire is fed through a tensioner and coiler, which winds it into a tight coil of specified outer diameter (450\u2013850 mm) and inner diameter (300\u2013700 mm). The coiler controls winding speed and tension to ensure consistent coil density.<\/li>\n<\/ol>\n<ol>\n<li>2. <strong>Strapping.<\/strong> Once a coil reaches the target size, strapping bands (steel or plastic) are applied automatically at regular intervals around the coil&#8217;s circumference to maintain structural integrity during handling and wrapping.<\/li>\n<\/ol>\n<ol>\n<li>3. <strong>Eye-through wrapping.<\/strong> The strapped coil is conveyed into the wrapping station. A toroidal ring passes through the coil&#8217;s eye, and the ring rotates around the coil&#8217;s cross-section while the coil remains stationary. Stretch film or paper is applied from a roll (50 mm core, 100\u2013250 mm OD, 100\u2013120 mm wide) with controlled pre-stretch (typically up to 250%). The orbital ring travels along the coil&#8217;s width (100\u2013300 mm), applying overlapping layers from one end to the other \u2014 wrapping the outer diameter, inner diameter, and both end faces in one continuous motion.<\/li>\n<\/ol>\n<ol>\n<li>4. <strong>Film cut and tail sealing.<\/strong> When the ring completes its traverse, the film is cut automatically at the end of the wrap. A clamp grips the film tail and secures it against the coil surface, preventing the wrap from loosening or unraveling during discharge, stacking, and transit.<\/li>\n<\/ol>\n<ol>\n<li>5. <strong>Stacking and discharge.<\/strong> The wrapped coil is conveyed to a stacking area where finished packages are stacked for labeling, strapping (if required), and palletizing. The line can handle coils weighing 10\u2013250 kg at a rate suitable for continuous production.<\/li>\n<\/ol>\n<p>The key advantage of the eye-through design is that the wrapping ring traverses the coil&#8217;s cross-section rather than rotating around a turntable. This is essential for wire coils where spinning a loosely wound coil on a turntable could cause layer slippage, and where the coil geometry (narrow width, large diameter relative to width) makes traditional pallet-wrapping approaches impractical.<\/p>\n<h2>Published Specifications<\/h2>\n<p>The FPW-300 is designed for the following wire coil dimensions and packaging parameters:<\/p>\n<p><\/p>\n<p><thead><\/thead><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p><\/p>\n<p>Because wire coil dimensions and throughput requirements vary between operations, final specifications are confirmed against the manufacturer&#8217;s datasheet. When evaluating an FPW-300 or equivalent eye-through orbital wrapping line, verify the following parameter groups with the supplier:<\/p>\n<table>\n<thead><tr><th>Parameter group<\/th>\n<th>What to confirm<\/th><\/tr><\/thead>\n<tbody>\n<tr><td>Coil dimensions<\/td>\n<td>Minimum and maximum coil OD, ID, width, and weight handled<\/td><\/tr>\n<tr><td>Wrapping material<\/td>\n<td>Compatible film\/paper types, core size, roll OD, and width<\/td><\/tr>\n<tr><td>Pre-stretch capability<\/td>\n<td>Maximum pre-stretch ratio for the wrapping film<\/td><\/tr>\n<tr><td>Overlap settings<\/td>\n<td>Programmable overlap range (typically 10\u201390%)<\/td><\/tr>\n<tr><td>Cycle time<\/td>\n<td>Coils per hour at your specified dimensions<\/td><\/tr>\n<tr><td>Line integration<\/td>\n<td>Conveyor heights, upstream coiler\/strapper compatibility, downstream stacking<\/td><\/tr>\n<tr><td>Power supply<\/td>\n<td>Electrical requirements and control voltage<\/td><\/tr>\n<tr><td>Footprint<\/td>\n<td>Machine envelope, loading direction, and clearance<\/td><\/tr>\n<\/tbody><\/table>\n<p>Request the manufacturer&#8217;s datasheet for your specific configuration and confirm each value against your coil drawings.<\/p>\n<h2>Engineering Calculation: Sizing Film and Wrap Coverage<\/h2>\n<p>A practical sizing exercise you can perform before specifying the machine:<\/p>\n<p><strong>Wrap coverage per revolution.<\/strong> The orbital ring travels along the coil&#8217;s width *W* while applying film with overlap ratio *r* and film width *w*. The number of ring passes *N* to cover the width is:<\/p>\n<p>N \u2248 W \/ (w \u00d7 (1 \u2212 r))<\/p>\n<p>*Example:* For a coil width of 200 mm, 120 mm film, and 30% overlap: N \u2248 200 \/ (120 \u00d7 0.7) \u2248 2.4 \u2192 3 passes per layer.<\/p>\n<p><strong>Film consumption.<\/strong> Total film length per coil = \u03c0 \u00d7 OD \u00d7 N \u00d7 number of layers, adjusted for pre-stretch. If the film is pre-stretched by factor *s*, the delivered film length per roll increases accordingly. Confirm actual pre-stretch values from the machine datasheet.<\/p>\n<p><strong>Cycle time estimation.<\/strong> Total cycle time = coiling time + strapping time + ring traverse time + film cut-and-clamp time + discharge time. Use your target output (coils per hour) to back-calculate required ring speed and confirm the machine&#8217;s rated performance covers it with margin.<\/p>\n<p>These calculations give you a defensible basis for comparing quotations and for estimating annual film consumption and cost per coil.<\/p>\n<h2>Selection Checklist<\/h2>\n<p>Before committing to an FPW-300 line:<\/p>\n<ul>\n<li>&#8211; <strong>Coil data confirmed:<\/strong> OD range, ID range, width, weight, winding type (rigid core vs. open).<\/li>\n<li>&#8211; <strong>Wrapping material specified:<\/strong> film or paper type, core size, roll dimensions, UV\/inhibitor requirements.<\/li>\n<li>&#8211; <strong>Pre-stretch capability required:<\/strong> confirm the machine can deliver the pre-stretch ratio needed for your film.<\/li>\n<li>&#8211; <strong>Throughput verified:<\/strong> coils per hour at your largest coil size, matched against calculated cycle time.<\/li>\n<li>&#8211; <strong>Line integration checked:<\/strong> upstream coiler\/strapper compatibility, conveyor heights, downstream stacking area.<\/li>\n<li>&#8211; <strong>Safety documentation requested:<\/strong> risk assessment per ISO 12100:2010 and CE compliance per EN 415-10.<\/li>\n<li>&#8211; <strong>Supplier verification:<\/strong> request the manufacturer&#8217;s full datasheet and confirm dimensions against your coil drawings.<\/li>\n<li>&#8211; <strong>Alternatives evaluated:<\/strong> compare against horizontal ring wrappers and turntable systems to confirm the eye-through orbital design is optimal for your wire coil geometry.<\/li>\n<\/ul>\n<h2>Safety<\/h2>\n<p>The FPW-300 line must be designed and operated in accordance with recognized safety standards:<\/p>\n<ul>\n<li>&#8211; <strong>EN 415-10<\/strong> covers safety requirements for palletizing and wrapping machinery, including guarding of moving orbital rings, interlocked access points, and emergency stop provisions.<\/li>\n<li>&#8211; <strong>ISO 12100:2010<\/strong> defines the risk assessment methodology \u2014 the process through which hazards such as rotating rings, pinch points, coil handling zones, and material feed points are identified and mitigated.<\/li>\n<\/ul>\n<p>Operationally, ensure:<\/p>\n<ul>\n<li>&#8211; Perimeter guarding or safety distance is maintained around the orbital ring during the cycle.<\/li>\n<li>&#8211; Interlocks are never bypassed, and access doors stop the ring before opening.<\/li>\n<li>&#8211; Operators are trained on coil handling procedures, especially for crane- or forklift-loaded coils.<\/li>\n<li>&#8211; Film and paper feed points are only accessed with the machine isolated.<\/li>\n<li>&#8211; Routine checks of emergency stops, light barriers, and interlocks are logged.<\/li>\n<\/ul>\n<p>Request the supplier&#8217;s risk assessment and confirm it addresses your specific coil handling method \u2014 this is where coil-specific hazards (e.g., coil slippage during loading) most often appear.<\/p>\n<h2>FAQ<\/h2>\n<p><strong>Why an eye-through orbital wrapper instead of a turntable?<\/strong><\/p>\n<p>Eye-through orbital wrappers rotate a ring around the coil&#8217;s cross-section while the coil remains stationary.
