The top plate comes down slowly, the coil shortens and its outer turns close up, and the plate holds at the bottom of the stroke.<\/p>\n<p>During the trial, a worker in a red hard hat checks the coil against the plate while the press holds. When the plate lifts, the coil springs back a little but stays compact. Beside the press stands the strapping unit with its curved arm and hydraulic cylinder, and the control screen carries the FHOPE mark.<\/p>\n<h2 id=\"how-it-works\">Inline compacting and strapping sequence<\/h2>\n<table>\n<thead>\n<tr>\n<th>Step<\/th>\n<th>What happens<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Infeed<\/td>\n<td>The coil runs in on the roller conveyor and stops under the press<\/td>\n<\/tr>\n<tr>\n<td>Press<\/td>\n<td>The top plate comes down and compacts the coil<\/td>\n<\/tr>\n<tr>\n<td>Hold<\/td>\n<td>The plate holds at the bottom of the stroke<\/td>\n<\/tr>\n<tr>\n<td>Strap<\/td>\n<td>The side unit bands the coil while it is held<\/td>\n<\/tr>\n<tr>\n<td>Release and outfeed<\/td>\n<td>The plate lifts and the strapped coil runs out<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The hold is the key step. Straps put on while the coil is compressed keep it at that height.<\/p>\n<h2 id=\"springback\">Controlling wire coil springback<\/h2>\n<p>A coil pressed and released without straps grows back a little. Illustrative example:<\/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>Coil height before pressing (illustrative)<\/td>\n<td>1,000 mm<\/td>\n<\/tr>\n<tr>\n<td>Height at the bottom of the stroke (illustrative)<\/td>\n<td>800 mm<\/td>\n<\/tr>\n<tr>\n<td>Height if released unstrapped (illustrative)<\/td>\n<td>850 mm<\/td>\n<\/tr>\n<tr>\n<td>Height kept when strapped under hold<\/td>\n<td>about 800 mm, less a little strap stretch<\/td>\n<\/tr>\n<tr>\n<td>Volume saved when strapped under hold, 1 \u2212 800 \u00f7 1,000<\/td>\n<td>about 20%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Strapping under hold keeps the full gain.

Keep people outside the press area while it cycles, and approach the coil only when the plate has stopped.<\/p>\n<p>The standards that apply depend on the destination market. For CE markets, ISO 12100 sets the risk-assessment method and EN 415-10 sets general requirements for packaging machines.<\/p>\n<h2 id=\"selection-checklist\">Selection checklist for a wire coil compacting and strapping machine<\/h2>\n<ul>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Coil OD, ID and height before pressing.<\/li>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Coil weight.<\/li>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Target height or density.<\/li>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Bands per coil and strap type.<\/li>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Coils per hour.<\/li>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Conveyor layout in and out.<\/li>\n<\/ul>\n<h2 id=\"engineering-faq\">Engineering FAQ<\/h2>\n<p>Q: Why strap while the press holds the coil?\nA: So the coil cannot spring back. In our example it keeps 800 mm instead of growing to 850 mm.<\/p>\n<p>Q: How much volume does compacting save?\nA: About 20% in our example, from 1,000 mm down to 800 mm high.<\/p>\n<p>Q: Where does compacting happen?\nA: On the roller conveyor, under the gantry press, so the coil does not leave the line.<\/p>\n<p>Q: Can it run inline with an existing conveyor?\nA: Yes. The coil runs in, stops under the press, is compacted and strapped on the roller conveyor and runs out.<\/p>\n<p>Q: What sets the hold time?\nA: The time the strapping unit needs for each band.<\/p>\n<p>Q: Can it handle different coil sizes?\nA: Yes, with the press stroke and conveyor stop set per size on trial.<\/p>\n<h2 id=\"next-step\">Next step<\/h2>\n<p>We plan your wire coil
