A rotary arm wrapper does the reverse: the pallet load stays stationary and the wrapping arm, carrying the stretch film carriage, rotates around it. Because the load never moves, unstable, very light or very heavy loads that might shift or collapse under rotation can be wrapped without being turned at all.<\/p>\n<p><a id=\"the-arm-and-the-drive\"><\/a><\/p>\n<h2>The arm and the drive<\/h2>\n<p>Smooth rotation comes from the arm drive. A precision bearing slewing ring carries the arm, and a variable-frequency drive controlled motor adjusts rotation speed. The wrap stays consistent from the first layer to the last, with the speed tuned to the film and the load. The whole assembly sits on a heavy-duty steel frame built to stay steady at working speed.<\/p>\n<p><a id=\"film-delivery-and-pre-stretch\"><\/a><\/p>\n<h2>Film delivery and pre-stretch<\/h2>\n<p>The film carriage is powered and pre-stretches the film mechanically before it touches the load. Pre-stretch elongates the film, which reduces the film you consume while increasing the containment force the wrap applies. The pre-stretch setting follows the film grade, and is confirmed per project rather than set to a single nominal value.<\/p>\n<p><a id=\"control-and-load-height\"><\/a><\/p>\n<h2>Control and load height<\/h2>\n<p>A programmable controller coordinates the arm, film carriage and line interface, and a touchscreen panel sets parameters, selects wrap patterns, monitors status and runs diagnostics. Photo-eyes detect the pallet height automatically, so film placement covers the load without over-wrapping below or above it, and the wrap pattern follows each product&#8217;s recipe.<\/p>\n<p><a id=\"automatic-film-feed\"><\/a><\/p>\n<h2>Automatic film feed<\/h2>\n<p>The cycle is automatic from start to finish. Film is clamped, cut and the tail is wiped and sealed against the load, so the finished wrap does not need an operator to trim or tuck film by hand. Between cycles the carriage returns to its start position and the machine is ready for the next pallet.<\/p>\n<p><a id=\"in-the-line-and-on-the-floor\"><\/a><\/p>\n<h2>In the line and on the floor<\/h2>\n<p>Because there is no heavy rotating platform, the rotary arm design does not put a turntable into the conveyor line. The machine claims its own dedicated floor space and the pallet passes through the wrapping zone on the conveyor. Load weight is carried by the conveyor or floor rather than lifted or rotated, so the practical limit follows the load transport, not the wrapper.<\/p>\n<p><a id=\"typical-configuration\"><\/a><\/p>\n<h2>Typical configuration<\/h2>\n<p>Figures below list functional design boundaries rather than numeric values, and are confirmed per project.<\/p>\n<table>\n<thead>\n<tr>\n<th style=\"text-align: left\">Parameter<\/th>\n<th style=\"text-align: left\">Typical range, confirmed per project<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"text-align: left\">Load<\/td>\n<td style=\"text-align: left\">footprint, height, weight<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Rotation<\/td>\n<td style=\"text-align: left\">variable-frequency drive<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Pre-stretch<\/td>\n<td style=\"text-align: left\">per film grade<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Control<\/td>\n<td style=\"text-align: left\">PLC and touchscreen HMI<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Height detect<\/td>\n<td style=\"text-align: left\">photo-eye automatic<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Electrical supply<\/td>\n<td style=\"text-align: left\">380 V three phase 50 Hz, or 220 V single phase for light machines, selected per project<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><a id=\"what-the-video-shows\"><\/a><\/p>\n<h2>What the video shows<\/h2>\n<p>Our footage shows a rotary arm pallet wrapping machine wrapping a stationary pallet.

Keep clear of the rotating arm while it runs. Safety light curtains and fencing interlocks protect the wrap zone, and an emergency stop sits at the operator position. Routine checks cover the slewing ring, arm drive, film carriage, sensors and guards, per the machine manual.<\/p>\n<p><a id=\"engineering-faq\"><\/a><\/p>\n<h2>Engineering FAQ<\/h2>\n<p>Q: What is the difference from a turntable wrapper?\nA: The arm rotates around the stationary pallet, so the load never turns and never risks shifting or collapsing.<\/p>\n<p>Q: Which loads suit a rotary arm machine?\nA: Unstable, very light or very heavy loads that a rotating platform could disturb.<\/p>\n<p>Q: How is rotation speed controlled?\nA: Through a variable-frequency drive on the arm motor, tuned to the film and load.<\/p>\n<p>Q: How is load height detected?\nA: Photo-eyes measure the pallet height automatically so film placement is exact without over-wrapping.<\/p>\n<p>Q: Does the machine finish the wrap itself?\nA: Yes. Film is clamped, cut and the tail is wiped and sealed automatically at cycle end.<\/p>\n<p><a id=\"next-step\"><\/a><\/p>\n<h2>Next step<\/h2>\n<ol>\n<li>Email us at info@fhopepack.com with your load envelope, film and throughput.<\/li>\n<li>We send a rotary arm wrapper proposal and a layout drawing within 48 hours.<\/li>\n<li>We arrange a site survey to confirm conveyor level and floor space.<\/li>\n<\/ol>\n<p><a id=\"related-reading\"><\/a><\/p>\n<h2>Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-turntable-pallet-wrapping-machine-and-top-sheet-covering\/\">Automatic turntable pallet wrapping machine and top sheet covering<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/robot-pallet-wrapping-machine\/\">Robot pallet wrapping machine<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-turntable-pallet-wrapping-machine-and-top-sheet-covering\/\">Pallet stretch wrapping: technology and best practices<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/Products\/\">FHOPE packing machinery product lines<\/a><\/li>\n<\/ul>\n<p><a id=\"sources-and-standards\"><\/a><\/p>\n<h2>Sources and standards<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.iso.org\/standard\/51528.html\">ISO 12100:2010 Safety of machinery, general principles for design and risk assessment<\/a><\/li>\n<li><a href=\"https:\/\/www.nen.nl\/en\/nen-en-415-10-2014-en-191845\">EN 415-10:2014 Safety of packaging machines, general requirements<\/a><\/li>\n<li><a href=\"https:\/\/www.iso.org\/standard\/83615.html\">EN ISO 13849-1:2023 Safety of machinery, safety-related parts of control systems<\/a><\/li>\n<\/ul>\n<p>FHOPE rotary arm pallet wrapping machine demonstration video.
