If you leave these coils unwrapped, the outer wraps will shift and unwind during handling. Moisture, shop dust, and grit enter the inner layers, and friction against shipping skids tears the product jacket.<\/p>\n<p>Wrapping stretch film through the eye forms a rigid, sealed composite donut. This annular binding clamps every layer together and prevents radial movement during transport. The protective film barrier locks out ambient humidity and airborne dirt while giving the package a uniform footprint. You can stack wrapped coils vertically without causing edge damage or surface scuffing.<\/p>\n<p>Manual hand-wrapping cannot deliver consistent results across eight-hour shifts. Operators stretch film unevenly, skip overlap sections, and struggle to maneuver rolls through narrow coil eyes. The FPH-300N automates this process by locking the rotation speeds of the orbital ring and support rollers together. The system wraps each coil uniformly in 23\u201335 seconds, eliminating manual strain and erratic material waste.<\/p>\n<hr \/>\n<h2><a id=\"how-the-coil-is-packed-step-by-step\"><\/a>How does an orbital ring wrap a coil, step by step?<\/h2>\n<p>The automated orbital wrapping cycle follows a strict mechanical progression:<\/p>\n<pre><code>[Load Coil] ---&gt; [Adjust Guide Arms] ---&gt; [Interlock Safe Start] ---&gt; [Orbital Eye-Wrap] ---&gt; [Manual\/Auto Cut] ---&gt; [Unload Coil]<\/code><\/pre>\n<ol>\n<li><strong>Loading<\/strong>: The operator places the coil vertically onto the heavy-duty polyurethane-coated support rollers. The open center eye rests over the bottom segment of the circular orbital track.<\/li>\n<li><strong>Alignment<\/strong>: Adjustable lateral guide rollers pivot inward against the sides of the coil. These rollers clamp the coil cheeks firmly to eliminate tipping or axial wandering during spinning.<\/li>\n<li><strong>Cycle Initiation<\/strong>: When all perimeter safety interlocks are verified closed, the operator starts the cycle from the floor-mounted pedestal panel. The variable-frequency drives ramp motor acceleration smoothly to prevent product shock.<\/li>\n<li><strong>Orbital Wrapping<\/strong>: The rotating ring carries the film carriage in a continuous vertical loop through the coil eye. At the same time, the driven support rollers rotate the coil horizontally around its core. The dual VFD system maintains exact film overlap and web tension throughout the process.<\/li>\n<li><strong>Film Severing<\/strong>: Once the controller hits the preset rotation target, the orbital ring stops accurately at its home dock. On the base FPH-300N, the operator severs the film web and presses the tail onto the outer bundle. An optional pneumatic cut-and-clamp arm can automate this task completely.<\/li>\n<li><strong>Unloading<\/strong>: The lateral guide rollers swing outward to clear the work zone. The operator rolls or hoists the wrapped coil directly onto the staging table or pallet station.<\/li>\n<\/ol>\n<hr \/>\n<h2><a id=\"fph-300n-technical-specifications\"><\/a>What coil sizes fit the FPH-300N?<\/h2>\n<p><strong>The FPH-300N processes coils with an inside diameter of 300\u2013700 mm, an outside diameter of 500\u20131,000 mm, and an axial width of 100\u2013300 mm. It handles product payloads up to 100 kg, running complete orbital wrapping sequences within 23\u201335 seconds per bundle.<\/strong><\/p>\n<p>These dimensional limits ensure the orbital carriage clears the internal core without striking the inner walls. If your production line handles oversized reels or bundles exceeding 1,000 mm OD or 100 kg total mass, you must route your product to the larger FPH-400 or FPH-500 series.<\/p>\n<p>The table below lists the factory operational ratings and technical specifications for the FPH-300N machine platform:<\/p>\n<table>\n<thead>\n<tr>\n<th style=\"text-align: left\">Parameter<\/th>\n<th style=\"text-align: left\">Operational Rating<\/th>\n<th style=\"text-align: left\">Engineering Unit \/ Details<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"text-align: left\"><strong>Coil Inner Diameter (ID)<\/strong><\/td>\n<td style=\"text-align: left\">300\u2013700<\/td>\n<td style=\"text-align: left\">mm<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\"><strong>Coil Outer Diameter (OD)<\/strong><\/td>\n<td style=\"text-align: left\">500\u20131,000<\/td>\n<td style=\"text-align: left\">mm<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\"><strong>Coil Width \/ Height<\/strong><\/td>\n<td style=\"text-align: left\">100\u2013300<\/td>\n<td style=\"text-align: left\">mm<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\"><strong>Maximum Payload<\/strong><\/td>\n<td style=\"text-align: left\">100<\/td>\n<td style=\"text-align: left\">kg<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\"><strong>Packaging Cycle Time<\/strong><\/td>\n<td style=\"text-align: left\">23\u201335<\/td>\n<td style=\"text-align: left\">seconds per coil (size dependent)<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\"><strong>Orbital Ring Velocity<\/strong><\/td>\n<td style=\"text-align: left\">20\u2013120<\/td>\n<td style=\"text-align: left\">r\/min (inverter controlled)<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\"><strong>Calculated Film Overlap<\/strong><\/td>\n<td style=\"text-align: left\">10%\u201390%<\/td>\n<td style=\"text-align: left\">adjustable via roller\/ring speed ratio<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\"><strong>Film Roll OD \/ Core ID<\/strong><\/td>\n<td style=\"text-align: left\">100\u2013180 \/ 50<\/td>\n<td style=\"text-align: left\">mm<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\"><strong>Film Web Width<\/strong><\/td>\n<td style=\"text-align: left\">90\u2013100<\/td>\n<td style=\"text-align: left\">mm<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\"><strong>Film Material Options<\/strong><\/td>\n<td style=\"text-align: left\">LLDPE, woven HDPE, VCI, creped paper<\/td>\n<td style=\"text-align: left\">20\u201350 \u00b5m thickness<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\"><strong>Drive Power Rating<\/strong><\/td>\n<td style=\"text-align: left\">1.9<\/td>\n<td style=\"text-align: left\">kW<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\"><strong>Electrical Supply<\/strong><\/td>\n<td style=\"text-align: left\">380 V, 50\/60 Hz, 3-Phase<\/td>\n<td style=\"text-align: left\">custom voltages on request<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><em>Note: For coils exceeding 1,000 mm OD or 100 kg weight, refer to the FPH-400 and FPH-500 series.<\/em><\/p>\n<hr \/>\n<h2><a id=\"worked-engineering-example-film-and-cycle-time\"><\/a>How much film and time does one coil take?<\/h2>\n<p><strong>For an 800 mm OD coil wrapped with 100 mm film at 50% overlap, the machine requires approximately 51 ring revolutions and 26 seconds of wrapping run time.

When the drive advances the outer circumference by 50 mm, the film advances only 25 mm along the inner eye surface. As a result, a 50% film overlap applied on the outer perimeter automatically deposits a 75% film overlap across the inside face. This geometry reinforces the inner bore against collapsing inward.<\/p>\n<hr \/>\n<h2><a id=\"overlap-tension-control-and-wrapping-materials\"><\/a>How do overlap, tension, and film choice work together?<\/h2>\n<p><strong>Film overlap, brake tension, and material grade must match the hoop stiffness of your product. Setting overlap to 10%\u201390% adjusts weather resistance, while maintaining tension between 5 N and 25 N prevents crushing thin tubing or leaving heavy hydraulic wire braids loose.<\/strong><\/p>\n<p>Operators must calibrate three main operating parameters to balance cycle performance and structural protection:<\/p>\n<ul>\n<li><strong>Overlap Adjustment (10%\u201390%)<\/strong>: You set the target overlap percentage directly on the touchscreen. The controller alters the gear ratio differential between the ring inverter and the roller inverter. We recommend an overlap of 60% or higher if your coils ship via open flatbeds or maritime sea containers.<\/li>\n<li><strong>Tension Regulation<\/strong>: The mechanical friction brake regulates payout web tension between 5 N and 25 N. Rigid steel-wire braided hydraulic hoses require high film tension between 18 N and 25 N to lock coil spring-back. Soft, thin-walled drip tubes require low tension between 5 N and 12 N to prevent core ovalization and lumen pinch.<\/li>\n<li><strong>Film Gauges and Formats<\/strong>: The system uses 25 \u00b5m cast or blown LLDPE stretch film for standard coils. You can load heavy 35\u201350 \u00b5m film when wrapping sharp metal-armored hoses or corrugated profiles.<\/li>\n<li><strong>Surface Protection<\/strong>: All base drive and side guide rollers feature an 85\u201390 Shore A polyurethane vulcanized coating. This layer protects smooth, colored, or high-gloss polymer jackets from scuff marks and oil residues.<\/li>\n<li><strong>Secondary Media<\/strong>: The carriage supports creped Kraft paper for breathability, anti-corrosion VCI films for steel fittings, and woven HDPE fabric for heavy transit abuse.<\/li>\n<\/ul>\n<hr \/>\n<h2><a id=\"application-selection-checklist\"><\/a>What should you verify before specifying a wrapper?<\/h2>\n<p>Before you install an orbital coil wrapper, verify your production metrics against this engineering checklist:<\/p>\n<ol>\n<li><strong>Dimensional Envelope<\/strong>: Confirm that your minimum and maximum coil ID, OD, and axial width match the 300\u2013700 mm ID and 500\u20131,000 mm OD windows.<\/li>\n<li><strong>Coil Mass and Handling<\/strong>: Check that your heaviest coil remains under 100 kg. Decide if operators will use cranes, run-in gravity conveyors, or manual lifting to stage parts.<\/li>\n<li><strong>Throughput Requirements<\/strong>: Define your target coils per hour. Verify whether a 15-second manual staging cycle meets your overall plant capacity.<\/li>\n<li><strong>Wrap Media Configuration<\/strong>: Select your primary packing material. Determine if you require single-layer LLDPE stretch film, composite paper-film wrapping, or branded identification tape.<\/li>\n<li><strong>Tail Clamping Strategy<\/strong>: Evaluate operational costs between manual tear-down and automated pneumatic clamp-and-cut mechanisms. Automated cutters eliminate 5\u20138 seconds of labor touch time per coil.<\/li>\n<li><strong>Line Integration<\/strong>: Decide whether the machine functions as an offline standalone cell, or connects directly between upstream extruders and downstream automated stackers.<\/li>\n<\/ol>\n<hr \/>\n<h2><a id=\"machinery-safety-compliance-en-415-10-and-iso-12100\"><\/a>Which safety standards apply?<\/h2>\n<p>The FPH-300N complies with EN 415-10 for packaging and wrapping machinery safety. Its structural layout follows the risk mitigation guidelines in ISO 12100:2010.<\/p>\n<ul>\n<li><strong>Rotary Pinch-Point Guarding<\/strong>: Heavy-duty fixed perimeter steel mesh screens enclose the rotating ring structure and driven support rollers.<\/li>\n<li><strong>Operator Access Control<\/strong>: Interlocked service panels wire directly to dual safety contactors. Opening any access gate triggers an immediate, unpowered Category 0 emergency stop.<\/li>\n<li><strong>Emergency Circuitry<\/strong>: Latching emergency stop mushroom pushbuttons sit within easy reach on the main electrical enclosure and the operator control console.<\/li>\n<li><strong>No-Reach Protocol<\/strong>: Reaching into the open coil eye while the ring is energized presents severe shear hazards. Hardware safety interlocks stop all motion if an operator interrupts the safety perimeter.<\/li>\n<\/ul>\n<hr \/>\n<h2><a id=\"frequently-asked-engineering-questions\"><\/a>What else do hose and pipe coil buyers ask?<\/h2>\n<h3>Can a single machine wrap both flexible garden hoses and rigid hydraulic assemblies?<\/h3>\n<p>Yes, provided both products fit the 300\u2013700 mm ID, 500\u20131,000 mm OD, and 100\u2013300 mm width ranges. You must adjust the mechanical friction brake between 5 N and 25 N to suit the crush resistance of each hose type.<\/p>\n<h3>How is the overlap percentage altered for different export packaging requirements?<\/h3>\n<p>You adjust the overlap by altering the speed differential between the ring motor and the roller motor. Operators modify this value using control panel dials or by selecting pre-programmed product recipes on the touchscreen.<\/p>\n<h3>What operational benefit does the optional automatic cut-and-clamp unit provide?<\/h3>\n<p>The automated mechanism cuts the film web and wipes the tail against the wrapped coil at cycle completion. This pneumatic feature eliminates manual operator cutting, saving 5\u20138 seconds of handling time per bundle.<\/p>\n<h3>How are coils exceeding 100 kg accommodated?<\/h3>\n<p>Coils weighing over 100 kg or measuring larger than 1,000 mm OD exceed the FPH-300N structural limits. We direct those applications to our FPH-400 or FPH-500 series, which use ground-mounted heavy idler roller beds.<\/p>\n<hr \/>\n<h2><a id=\"conclusion\"><\/a>Conclusion and Project Sizing<\/h2>\n<p>Selecting your orbital packaging system comes down to your coil dimensions and wall rigidity:<\/p>\n<ul>\n<li><strong>Dimensional Routing<\/strong>: If your coil falls within 300\u2013700 mm ID, 500\u20131,000 mm OD, 100\u2013300 mm width, and stays below 100 kg, choose the <strong>FPH-300N<\/strong>. If your product exceeds 1,000 mm OD or 100 kg, move to the heavy-frame <strong>FPH-400 or FPH-500<\/strong>.<\/li>\n<li><strong>Tension Selection<\/strong>: Run rigid wire-braided hydraulic hoses at <strong>18\u201325 N<\/strong> to secure internal spring-back.
