A press arm holds the bundle down while a ring wraps it. Our E1000 wrapper takes bundles of 400\u20131,000 mm across, over 1,000 mm long and 50\u2013400 kg, at conveyor speeds of 3\u201312 m\/min. A worked example checks the fit, finds the top speed for 50% overlap and works out bundles per hour.<\/p>\n<\/blockquote>\n<iframe loading=\"lazy\" width=\"940\" height=\"535\" src=\"https:\/\/www.youtube.com\/embed\/aVLMdNAZxp4\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe>\n<h2 id=\"table-of-contents\">Table of Contents<\/h2>\n<ul>\n<li><a href=\"#why\">Why wrap timber bundles<\/a><\/li>\n<li><a href=\"#machine\">The wrapping station<\/a><\/li>\n<li><a href=\"#specs\">E1000 data<\/a><\/li>\n<li><a href=\"#example\">Worked example: a 500 \u00d7 300 mm timber bundle<\/a><\/li>\n<li><a href=\"#line\">Adding strapping, bearers and corner boards<\/a><\/li>\n<li><a href=\"#selection-checklist\">Selection checklist<\/a><\/li>\n<li><a href=\"#safety\">Safety: EN 415-10 and ISO 12100<\/a><\/li>\n<li><a href=\"#engineering-faq\">Engineering FAQ<\/a><\/li>\n<li><a href=\"#next-step\">Next step<\/a><\/li>\n<li><a href=\"#related-reading\">Related reading<\/a><\/li>\n<li><a href=\"#sources\">Sources<\/a><\/li>\n<\/ul>\n<h2 id=\"why\">Why wrap timber bundles<\/h2>\n<p>Sawn and planed timber picks up dirt, rain and sun damage in a yard or on a truck. Loose pieces also shift and splinter in handling. A spiral of stretch film binds the bundle into one block and keeps the surface clean, and the timber stays visible for checking. For dressed timber and mouldings, film is often used together with straps.<\/p>\n<p>Green timber still gives off moisture, and a fully sealed wrap can trap it and cause mould. For green timber, a lower overlap leaves an open spiral that lets it breathe, or paper or woven wrap can be used instead of film. Kiln-dried timber can take a full weather wrap.<\/p>\n<h2 id=\"machine\">The wrapping station<\/h2>\n<p>The timber bundle runs in on a green belt conveyor. At the wrapping station, a press arm with a yellow pad comes down onto the top of the bundle and holds the pieces in line.<\/p>\n<p>The bundle passes through the opening of a white ring housing, where the turning ring lays stretch film round it as it moves. A handwheel at the ring sets the film roll position. The wrapped bundle then runs out on the outfeed belt. A light curtain stands across the infeed of the station.<\/p>\n<h2 id=\"specs\">E1000 data<\/h2>\n<table>\n<thead>\n<tr>\n<th style=\"text-align: left\">Item<\/th>\n<th style=\"text-align: left\">Value<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"text-align: left\">Bundle size<\/td>\n<td style=\"text-align: left\">across 400\u20131,000 mm; length over 1,000 mm<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Bundle weight<\/td>\n<td style=\"text-align: left\">50\u2013400 kg<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Infeed conveyor<\/td>\n<td style=\"text-align: left\">2,000 mm long \u00d7 1,200 mm wide<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Outfeed conveyor<\/td>\n<td style=\"text-align: left\">2,000 mm long \u00d7 800 mm wide; wider bundles get side support, set in the layout<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Conveyor speed<\/td>\n<td style=\"text-align: left\">3\u201312 m\/min<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Ring speed<\/td>\n<td style=\"text-align: left\">about 10\u201360 r\/min<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Material<\/td>\n<td style=\"text-align: left\">LLDPE stretch film, paper or woven; 100\u2013500 mm wide, 50 mm core<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Machine size<\/td>\n<td style=\"text-align: left\">about 4,800 \u00d7 1,800 \u00d7 2,000 mm<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Power<\/td>\n<td style=\"text-align: left\">about 4.5 kW, AC 380 V 50 Hz 3 ph; 24 V DC controls<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Air<\/td>\n<td style=\"text-align: left\">5\u20138 kgf\/cm\u00b2 (about 5\u20138 bar)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 id=\"example\">Worked example: a 500 \u00d7 300 mm timber bundle<\/h2>\n<p>Illustrative bundle: 500 mm wide, 300 mm high, 3 m long, wrapped with 250 mm film at 50% overlap and the ring at its top speed of 60 r\/min.

At 50% overlap the ring limits the conveyor to 7.5 m\/min, well below its 12 m\/min top speed. That gives a bundle every 32 s, or about 112 an hour. Running faster than 7.5 m\/min would thin the overlap, so for higher output a wider film roll is the first step.<\/p>\n<h2 id=\"line\">Adding strapping, bearers and corner boards<\/h2>\n<p>A timber line often needs more than film. We build lines that also:<\/p>\n<ul>\n<li><strong>Strap the bundle<\/strong> before or after wrapping.<\/li>\n<li><strong>Feed timber bearers<\/strong> under the bundle automatically, so a forklift can lift it.<\/li>\n<li><strong>Add cardboard corner protectors<\/strong> at the top corners before strapping.<\/li>\n<\/ul>\n<p>For larger bundles, our orbital wrapper with wooden feeder places timber blocks at the top and bottom of the bundle and wraps them in.<\/p>\n<h2 id=\"selection-checklist\">Selection checklist<\/h2>\n<ol>\n<li>Bundle length, width, height and weight.<\/li>\n<li>Film, paper or woven wrap, and overlap.<\/li>\n<li>Bundles per hour.<\/li>\n<li>Strapping, bearers under the bundle, corner protection.<\/li>\n<li>Conveyor connection to the stacker.<\/li>\n<\/ol>\n<h2 id=\"safety\">Safety: EN 415-10 and ISO 12100<\/h2>\n<p>We design the wrapper to EN 415-10 and assess its risks to ISO 12100.

An open spiral, paper or woven wrap lets moisture out.<\/p>\n<p>Q: What sets the speed?\nA: The ring speed and film width set the top conveyor speed for a given overlap.<\/p>\n<p>Q: Can it put bearers under the bundle?\nA: Yes, with an automatic timber feeder.<\/p>\n<p>Q: Which standard applies?\nA: EN 415-10 for the machine, and ISO 12100 for the risk assessment.<\/p>\n<h2 id=\"next-step\">Next step<\/h2>\n<ol>\n<li><strong>Send bundle sizes, weights and output<\/strong> to info@fhopepack.com.<\/li>\n<li><strong>We plan<\/strong> the wrapper and any strapping or bearer feeding.<\/li>\n<li><strong>We reply within 24 hours<\/strong> with a layout and quotation.<\/li>\n<\/ol>\n<h2 id=\"related-reading\">Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/Automatic-horizontal-stretch-wrapper\/E1000-horizontal-stretch-wrapper.html\">E1000 horizontal stretch wrapper (product)<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/Customize-orbital-wrapper\/orbital-wrapper-with-wooden-feeder.html\">Orbital wrapper with wooden feeder (product)<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/wooden-timber-strapping-and-wrapping-machine\/\">Wooden timber strapping and wrapping machine<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/horizontal-ring-orbital-stretch-wrapping-machine\/\">Horizontal ring orbital stretch wrapping machine<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-lumber-bundle-strapping-packing-line\/\">Automatic lumber bundle strapping packing line<\/a><\/li>\n<\/ul>\n<h2 id=\"sources\">Sources<\/h2>\n<ul>\n<li>FHOPE product pages: E1000 horizontal stretch wrapper; orbital wrapper with wooden feeder<\/li>\n<li>FHOPE project notes on lumber packing options<\/li>\n<li>Our timber bundle wrapper shown above<\/li>\n<li>Worked example: illustrative figures<\/li>\n<li>Standards: EN 415-10; ISO 12100:2010<\/li>\n<\/ul>\n<p><strong>Last reviewed:<\/strong> 2026-10-19<\/p>","protected":false},"excerpt":{"rendered":"<p>Executive summary Timber bundle packaging with a horizontal stretch wrapper holds a stack of sawn timber together in a tight spiral of film as it runs along a conveyor.
