The carriage traverse speed and cradle drive are linked through inverter-driven soft start and soft stop control [manufacturer rating], which prevents jerking or edge telescoping. Because the roll rests horizontally in the cradle, delicate fabrics are never stood on end, and heavy rolls do not require loading onto an elevated vertical turntable.<\/p>\n<h2 id=\"turns\">Estimating roll turns and film<\/h2>\n<p>The carriage moves a set linear distance for each revolution of the roll. The following is an illustrative example for a roll 1,600 mm long and 400 mm in diameter, using 500 mm wide film at a 50% overlap rate:<\/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>Roll length<\/td>\n<td>1,600 mm<\/td>\n<\/tr>\n<tr>\n<td>Advance per roll turn, 500 \u00d7 (1 \u2212 0.5)<\/td>\n<td>250 mm<\/td>\n<\/tr>\n<tr>\n<td>Roll turns to cover the length (1,600 \u00f7 250)<\/td>\n<td>about 7<\/td>\n<\/tr>\n<tr>\n<td>Roll circumference, \u03c0 \u00d7 400 mm<\/td>\n<td>1,257 mm<\/td>\n<\/tr>\n<tr>\n<td>Film laid on the roll surface, 7 \u00d7 1.257 m<\/td>\n<td>about 8.8 m<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><em>Note: Values shown are for engineering illustration. Power pre-stretch systems can deliver up to 250% pre-stretch ratio (with 100% to 300% regulation range) [manufacturer rating], substantially reducing raw film resin consumption.<\/em><\/p>\n<p>Extra turns at each end reinforce the film tails, secure loose edge flaps, and fold protection around the roll margins. These end-wrap reinforcement turns are set directly in the recipe parameters.<\/p>\n<h2 id=\"roll-care\">Protecting the roll<\/h2>\n<table>\n<thead>\n<tr>\n<th>Concern<\/th>\n<th>How it is handled<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Flat spots on the cloth<\/td>\n<td>The roll lies supported in a dual-roller cradle, distributing load instead of resting on a flat bed<\/td>\n<\/tr>\n<tr>\n<td>Surface marking and scuffing<\/td>\n<td>Cradle rollers are lined with polyurethane (PU) sleeves to prevent scuff marks [manufacturer rating]<\/td>\n<\/tr>\n<tr>\n<td>Dust and damp in storage<\/td>\n<td>Full spiral film coverage protects the entire outside diameter<\/td>\n<\/tr>\n<tr>\n<td>Loose cloth end<\/td>\n<td>Initial base wraps lock the tail down without requiring tape or staples<\/td>\n<\/tr>\n<tr>\n<td>Roll ends<\/td>\n<td>Extra programmed end turns fold film over the roll edges<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Film tension must be precisely adjusted on the control interface. Excessive wrap tension on a soft roll can create pressure ridges, compress interior cloth layers, or stretch sensitive knit fabrics out of shape. For delicate materials, the carriage feed tension is minimized to protect product integrity.<\/p>\n<h2 id=\"safety\">Controls and safety<\/h2>\n<p>The main control cabinet features an integrated PLC and operator HMI for configuring wrap recipes, roll rotation speed, carriage travel, and film tension [manufacturer rating]. A high-visibility emergency stop button (red mushroom push button) [manufacturer rating] and standardized warning plates provide operational safety.<\/p>\n<ul>\n<li><strong>Clearances<\/strong>: Personnel must stay clear of the turning cradle rollers and the overhead traverse carriage during automatic operation.<\/li>\n<li><strong>Safety architecture<\/strong>: The electrical and mechanical design complies with market-specific packaging safety standards. In CE markets, risk assessments are governed by ISO 12100, and overall safety and hygiene requirements follow EN 415-10. Optical safety light curtains and safety fence interlocks can be integrated for automated cell safety.<\/li>\n<\/ul>\n<h2 id=\"selection-checklist\">Selection checklist for a roll stretch wrapper<\/h2>\n<ul>\n<li>Roll diameter and length, smallest to largest.<\/li>\n<li>Roll weight.<\/li>\n<li>Fabric type and how easily it marks.<\/li>\n<li>Film cover only, or film plus end caps.<\/li>\n<li>Rolls per hour.<\/li>\n<li>How rolls are loaded: crane, forklift or conveyor.<\/li>\n<\/ul>\n<h2 id=\"engineering-faq\">Engineering FAQ<\/h2>\n<p><strong>Q: Does the roll stand up during wrapping?<\/strong>\nA: No. It lies horizontally on its side in the cradle and turns, while the carriage travels along the top beam. This prevents core telescoping and crushed roll ends.<\/p>\n<p><strong>Q: How many turns does a roll need?<\/strong>\nA: Roll length divided by the advance per turn gives the traverse turns, which is about 7 turns in our 1,600 mm example. Reinforcement end turns are added at both ends in the wrap recipe.<\/p>\n<p><strong>Q: How much film goes on one roll?<\/strong>\nA: Approximately 8.8 m of film is laid on the surface in our worked example (for a 400 mm diameter roll using 500 mm film at 50% overlap, before accounting for pre-stretch expansion and extra end turns).<\/p>\n<p><strong>Q: Will the film mark soft fabric?<\/strong>\nA: High film tension can crease or mark soft fabrics. The carriage tension should be set low via the HMI recipe, and tested on sample rolls to confirm surface protection.<\/p>\n<p><strong>Q: Are the roll ends covered?<\/strong>\nA: Extra programmed turns at each end overhang and fold film around the outer roll edges. For complete moisture-tight sealing against long-term storage conditions, separate circular end discs or protective caps can be added before wrapping.<\/p>\n<h2 id=\"next-step\">Next step<\/h2>\n<p>We plan your roll stretch wrapper in three steps:<\/p>\n<ol>\n<li><strong>Submit your layout drawing<\/strong> with roll sizes, weights, and required hourly output to <strong>info@fhopepack.com<\/strong>.<\/li>\n<li><strong>Receive a proposal within 48 hours<\/strong>, including frame sizing, cradle roller specifications, and wrap cycle calculations.<\/li>\n<li><strong>Book a site survey<\/strong> to check infeed roll loading clearances and available floor space.<\/li>\n<\/ol>\n<h2 id=\"related-reading\">Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/Customize-orbital-wrapper\/Horizontal_orbital-stretch-wrapper.html\">Horizontal orbital stretch wrapper<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/Automatic-horizontal-stretch-wrapper\/E300-horizontal-stretch-wrapper.html\">E300 horizontal stretch wrapper<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/horizontal-stretch-wrapper-for-paper-light-products\/\">Video: horizontal stretch wrapper for light paper products<\/a><\/li>\n<\/ul>\n<h2 id=\"sources\">Sources<\/h2>\n<ul>\n<li>Machine content: FHOPE engineering team, 2026-10-04<\/li>\n<li>Coil wrapping systems technical reference (FPS-300 horizontal coil wrapper platform)<\/li>\n<li>Stretch carriage control specifications (A300 stretch wrapper program platform)<\/li>\n<li>Turns and film calculation: Worked engineering example, illustrative values<\/li>\n<li>Standards compliance: <a href=\"https:\/\/www.iso.org\/standard\/51528.html\">ISO 12100:2010<\/a>, <a href=\"https:\/\/www.nen.nl\/en\/nen-en-415-10-2014-en-191845\">EN 415-10:2014<\/a><\/li>\n<\/ul>\n<p><strong>Last reviewed:<\/strong> 2026-10-29<\/p>","protected":false},"excerpt":{"rendered":"<p>Executive summary A fabric roll has to be wrapped round its whole outside without flattening it or pulling the cloth out of line.
