Dust settles on it in the warehouse. Rain or condensate drips onto it in open yards and reefer trucks. For beverage, frozen food and bagged goods, an open top means dirty or wet product at delivery.<\/p>\n<p>A top sheet closes that gap. The sheet drapes over the top edges, and the stretch wrap pins the hanging edges to the sides. The load is then closed on every face except the pallet base.<\/p>\n<h2 id=\"sequence\">How the B300 covers and wraps a load<\/h2>\n<ol>\n<li><strong>Infeed.<\/strong> A forklift places the pallet on the infeed conveyor. The motorised conveyor carries it to the wrapping position.<\/li>\n<li><strong>Top sheet.<\/strong> With the pallet at the wrapping position, an overhead top-sheet beam lowers over the load and drapes a sheet of PE film or foam across the top. On conveyor-fed versions we can instead lay the sheet as the pallet travels in.<\/li>\n<li><strong>Stretch wrap.<\/strong> Once the sheet is in place, the turntable rotates and the film carriage travels up and down the column. Pre-stretched LLDPE film wraps the sides, with separate counts for bottom, middle and top winds.<\/li>\n<li><strong>Cut and wipe.<\/strong> The mechanical hand clamps the film with scissor-like gripper bars and cuts it with a heated wire. A soft brush wipes the tail onto the load. The clamp then holds the film for the next pallet.<\/li>\n<li><strong>Outfeed.<\/strong> The wrapped pallet leaves on the outfeed conveyor for forklift pick-up.<\/li>\n<\/ol>\n<p>A PLC runs the whole cycle with no operator help. The infeed and outfeed conveyors are optional, so the B300 can also stand alone.<\/p>\n<h2 id=\"specs\">B300 specifications<\/h2>\n<table>\n<thead>\n<tr>\n<th style=\"text-align: left\">Item<\/th>\n<th style=\"text-align: left\">B300<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"text-align: left\">Loads per hour<\/td>\n<td style=\"text-align: left\">24 minimum<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Maximum load weight<\/td>\n<td style=\"text-align: left\">1,800 kg (turntable rated 2,000 kg)<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Turntable<\/td>\n<td style=\"text-align: left\">2,200 mm diameter, about 400 mm high, chain drive, ring gear bearing<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Turntable speed<\/td>\n<td style=\"text-align: left\">up to 12 rpm, adjustable, soft start and stop<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Film<\/td>\n<td style=\"text-align: left\">LLDPE, 0.025 mm thick, 500 mm wide, 76 mm core<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Pre-stretch<\/td>\n<td style=\"text-align: left\">250%, optional 100% to 300%<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Carriage speed<\/td>\n<td style=\"text-align: left\">2.9 m\/min, set by inverter<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Wind counts<\/td>\n<td style=\"text-align: left\">bottom, middle and top, 0\u201399 each<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Controls<\/td>\n<td style=\"text-align: left\">PLC, HMI and separate buttons, photocell load height sensor<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Power<\/td>\n<td style=\"text-align: left\">AC 380 V, 3 phase, 50 Hz<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Air supply<\/td>\n<td style=\"text-align: left\">6\u20138 kgf\/cm\u00b2; air consumption confirmed per order<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 id=\"example\">Worked example: top sheet size and film use<\/h2>\n<p>Take a 1,200 \u00d7 1,000 mm pallet with a 1,500 mm load. These are illustrative customer figures.<\/p>\n<p><strong>Top sheet size.<\/strong> Let the sheet hang 200 mm down each side, an illustrative drop. Sheet size is then (1,200 + 2 \u00d7 200) \u00d7 (1,000 + 2 \u00d7 200) = 1,600 \u00d7 1,400 mm. We set the drop on trials so the top winds catch it.<\/p>\n<p><strong>Spiral pitch.<\/strong> At the top turntable speed of 12 rpm and a carriage speed of 2.9 m\/min, the carriage rises 2,900 \u00f7 12 = 242 mm per turn. With 500 mm film that leaves an overlap of 1 \u2212 242 \u00f7 500 = 52%.<\/p>\n<p><strong>Film for one pass up.<\/strong> The carriage needs 1,500 \u00f7 242 = 6.2 turns to climb the load. Each turn wraps a perimeter of 2 \u00d7 (1.2 + 1.0) = 4.4 m. That puts about 27 m of stretched film on the load. At 250% pre-stretch, 1 m off the roll becomes 3.5 m on the load. So the pass uses about 27 \u00f7 3.5 = 7.7 m of film from the roll, before top and bottom winds.<\/p>\n<h2 id=\"top-winds\">Setting the top winds to hold the sheet<\/h2>\n<p>The top winds do the work of holding the sheet. Each wind of 500 mm film covers the 200 mm drop and leaves 300 mm on the load sides below it. Two or three top winds usually lock the sheet; we confirm the count on your load. Extra top winds help on wet routes, where wind can lift a loose sheet corner.<\/p>\n<h2 id=\"selection-checklist\">Selection checklist: what to send us<\/h2>\n<ol>\n<li>Pallet size and the largest load footprint.<\/li>\n<li>Load height range and heaviest load.<\/li>\n<li>Loads per hour.<\/li>\n<li>Top sheet material: PE film or foam.<\/li>\n<li>Whether you need infeed and outfeed conveyors.<\/li>\n<li>Product type, for example beverage, frozen food or bags.<\/li>\n<li>Power and compressed air at site.<\/li>\n<\/ol>\n<h2 id=\"safety\">Safety and EN 415-6<\/h2>\n<p>We design pallet wrappers to EN 415-6 and assess risks to ISO 12100. The turning turntable, the moving carriage and the conveyors are the main hazards. For an inline B300 we enclose the wrap zone with interlocked fencing. Muting light curtains guard the conveyor openings, letting pallets pass while stopping the machine for a person.<\/p>\n<p>A standalone B300 without fencing gets an area scanner or pressure mats round the turntable instead. A red mushroom-head emergency stop and a lockable electrical disconnect come as standard.<\/p>\n<h2 id=\"engineering-faq\">Engineering FAQ<\/h2>\n<p>Q: Does the top sheet slow the cycle?\nA: When the beam places the sheet at the wrapping position, its stroke adds to the cycle. Laying the sheet on the infeed instead overlaps it with the conveyor move. We size the cycle on your loads per hour.<\/p>\n<p>Q: Can it use foam instead of film for the top?\nA: Yes. The covering unit takes PE film or plastic foam.<\/p>\n<p>Q: What if my loads are lighter than the turntable rating?\nA: That is fine. The B300 is rated for loads up to 1,800 kg.<\/p>\n<p>Q: Which safety standards apply?\nA: ISO 12100 for the risk assessment and EN 415-6 for pallet wrapping machines, in CE markets.<\/p>\n<h2 id=\"next-step\">Next step<\/h2>\n<ol>\n<li><strong>Email your pallet sizes, load heights and loads per hour<\/strong> to <strong>info@fhopepack.com<\/strong>.<\/li>\n<li><strong>We reply within 24 hours with a proposal<\/strong> naming the model and options.<\/li>\n<li><strong>We send a layout drawing<\/strong> with conveyors and guarding.<\/li>\n<\/ol>\n<h2 id=\"related-reading\">Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/Automatic-pallet-wrapping-machine\/pallet-wrapping-machine-B300.html\">B300 automatic pallet wrapping machine<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/Automatic-pallet-wrapping-machine\/pallet-wrapping-machine-B100.html\">B100 automatic pallet wrapping machine<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/pallet-wrapping-machinery\/\">Pallet wrapping machinery for online packing with top sheet covering<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/how-pe-sheet-dispenser-for-automatic-pallet-covering\/\">How the PE sheet dispenser works for automatic pallet covering<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/inline-turntable-pallet-wrapper\/\">Inline turntable pallet wrapper<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-rotary-arm-pallet-wrapping-machine-with-top-sheet-covering\/\">Automatic rotary arm pallet wrapping machine with top sheet covering<\/a><\/li>\n<\/ul>\n<h2 id=\"sources\">Sources<\/h2>\n<ul>\n<li>Specifications: FHOPE B300 automatic pallet wrapping machine product page<\/li>\n<li>Machine video: <a href=\"https:\/\/www.youtube.com\/watch?v=jdR8UX7tnFY\">pallet wrapper with top sheet dispenser on YouTube<\/a><\/li>\n<li>Sheet size and film use: our worked example, illustrative pallet figures<\/li>\n<li>Standards: EN 415-6 (pallet wrapping machines); ISO 12100:2010<\/li>\n<\/ul>\n<p><strong>Last reviewed:<\/strong> 2026-10-17<\/p>","protected":false},"excerpt":{"rendered":"<p>Executive summary Our B300 automatic pallet wrapper lays a sheet of PE film or foam over the top of the load, then stretch wraps the sides so the wrap locks the sheet&#8217;s edges down.
