Motor-driven conveyors feed the rod in and carry it out, and a board centres rods of different diameter in the ring. It takes rods 10 to 200 mm across and 10 to 100 kg.

A tight spiral of stretch film on each rod keeps the surface clean and dry until it is used.<\/p>\n<p>Wrapping by hand is slow on long pieces and leaves loose ends. Our S200 lays the film at a set overlap along the whole length, at conveyor speed.<\/p>\n<h2 id=\"how\">How the rod passes through the ring<\/h2>\n<ol>\n<li><strong>Infeed.<\/strong> The rod lies on the motor-driven entrance conveyor and moves towards the ring.<\/li>\n<li><strong>Start.<\/strong> A photocell detects the rod and sets the wrapping position automatically.<\/li>\n<li><strong>Wrap.<\/strong> The ring turns round the rod as the conveyor carries it through. Film tension is set by a brake device.<\/li>\n<li><strong>Press and exit.<\/strong> Press rollers at the exit keep the wrapped rod steady on the outlet conveyor.<\/li>\n<li><strong>Finish.<\/strong> The operator cuts the film.

If the rod is off centre in the ring, the film wraps tighter on one side.<\/p>\n<p>The S200 has a board that moves up and down to centre each diameter in the ring. The operator sets it with a hand wheel when the rod size changes. Double rings and double drive wheels keep the ring turning smoothly and steadily.<\/p>\n<h2 id=\"specs\">S200 specifications<\/h2>\n<table>\n<thead>\n<tr>\n<th style=\"text-align: left\">Item<\/th>\n<th style=\"text-align: left\">S200<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"text-align: left\">Product length<\/td>\n<td style=\"text-align: left\">over 300 mm<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Product diameter<\/td>\n<td style=\"text-align: left\">10\u2013200 mm<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Product weight<\/td>\n<td style=\"text-align: left\">10\u2013100 kg<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Entrance conveyor<\/td>\n<td style=\"text-align: left\">2,000 mm, motor driven<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Outlet conveyor<\/td>\n<td style=\"text-align: left\">2,000 mm, motor driven<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Conveying speed<\/td>\n<td style=\"text-align: left\">4\u201312 m\/min<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Ring speed<\/td>\n<td style=\"text-align: left\">20\u2013120 r\/min, by converter<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Stretch film<\/td>\n<td style=\"text-align: left\">LLDPE, 120\u2013200 mm wide, roll OD 150\u2013200 mm, core 50 mm<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Power<\/td>\n<td style=\"text-align: left\">about 2.1 kW, AC 380 V, 60 Hz<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Options<\/td>\n<td style=\"text-align: left\">other packing materials; conveyor length; automatic cutter<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 id=\"example\">Worked example: overlap, time and weight for a 100 mm rod<\/h2>\n<p>Take aluminium rods 100 mm in diameter and 3,000 mm long, wrapped with 150 mm film.
