During standard processing, flat metal sheets are aligned on the table surface and guided directly into the driven laminating rollers.<\/p>\n<p>The protective film coil delivers printed surface film\u2014such as clear or opaque stock bearing the &#8220;SUS304&#8221; metallurgical grade designation. The continuous film web is pressed evenly across the top face of the sheet as the driven roller pulls the work piece through the station. An integrated safety guard covers the entire laminating roller section to isolate the mechanical pinch point during continuous feeding.<\/p>\n<h2 id=\"how-it-works\">How the film applicator works<\/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>Feed<\/td>\n<td>Operators lay the sheet on the table and push it to the rollers<\/td>\n<\/tr>\n<tr>\n<td>Film feed<\/td>\n<td>Printed film unwinds from the roll at the infeed<\/td>\n<\/tr>\n<tr>\n<td>Press<\/td>\n<td>Rollers press the film onto the sheet face<\/td>\n<\/tr>\n<tr>\n<td>Separation<\/td>\n<td>The film is parted at the end of each sheet<\/td>\n<\/tr>\n<tr>\n<td>Outfeed<\/td>\n<td>The covered sheet runs out along the table<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The protective film carries the metallurgical grade or corporate branding along the entire sheet length, ensuring full batch traceability after secondary laser cutting, punching, or shearing. The print is positioned facing outward, allowing clear visibility on the sheet face.<\/p>\n<p>On standard manual configurations, line operation is managed by two operators\u2014one handling sheet alignment and feeding, and one managing outfeed handling and film parting [manufacturer rating]. For continuous high-throughput installations, the film length is verified against sheet dimensions by a servo system, and an automatic synchronized cutter separates the film web cleanly in the gap between successive sheets to maintain uninterrupted cycle times [manufacturer rating].<\/p>\n<h2 id=\"why-film\">Why stainless sheet is filmed<\/h2>\n<table>\n<thead>\n<tr>\n<th>Risk<\/th>\n<th>How the film helps<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Scratches in stacking<\/td>\n<td>The film takes the contact between sheets<\/td>\n<\/tr>\n<tr>\n<td>Marks in cutting and bending<\/td>\n<td>The film stays on through fabrication<\/td>\n<\/tr>\n<tr>\n<td>Dirt and fingerprints<\/td>\n<td>The face stays clean until the film is peeled<\/td>\n<\/tr>\n<tr>\n<td>Mixed grades<\/td>\n<td>Printed film shows the grade on every sheet<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The protective foil remains adhered throughout storage, handling, press-brake bending, and stamping operations, and is peeled off once the final product is assembled. Selecting the correct adhesive tack level matching your specific sheet surface finish (2B, No. 4, hairline, or mirror BA) ensures reliable adhesion during fabrication without adhesive transfer upon peeling.<\/p>\n<h2 id=\"film-per-sheet\">Planning film per sheet<\/h2>\n<p>Each sheet consumes its exact product length plus the clearance gap maintained between sheets during infeed. Illustrative example for a 2,000 mm sheet, 50 mm gap, and a 500 m film roll:<\/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>Sheet length<\/td>\n<td>2,000 mm<\/td>\n<\/tr>\n<tr>\n<td>Gap between sheets (illustrative)<\/td>\n<td>50 mm<\/td>\n<\/tr>\n<tr>\n<td>Film per sheet, 2,000 + 50<\/td>\n<td>2,050 mm<\/td>\n<\/tr>\n<tr>\n<td>Roll length (illustrative)<\/td>\n<td>500 m<\/td>\n<\/tr>\n<tr>\n<td>Sheets per roll, 500 \u00f7 2.05<\/td>\n<td>about 243<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Minimizing the gap between successive sheets reduces consumable film waste, while maintaining adequate clearance for a clean, square transverse cut between sheets. In automated installations, film feed and pre-cutting cycles are synchronized to the measured workpiece length via the servo control system [manufacturer rating].<\/p>\n<h2 id=\"safety\">Controls and safety<\/h2>\n<p>The laminating roller section is fully enclosed with a mechanical barrier guard. Because the roller nip point presents an inrunning drawing-in hazard as material enters, operators must support and guide sheets strictly from the entry table and maintain safe hand clearance away from the laminating rollers. The machine must be brought to a complete, interlocked stop before executing film roll changeovers or performing web path adjustments.<\/p>\n<p>Equipment compliance is configured per destination territory requirements. For CE-regulated markets, mechanical risk assessments comply with ISO 12100, and general safety requirements for sheet lamination and wrapping units adhere to EN 415-10.<\/p>\n<h2 id=\"selection-checklist\">Selection checklist for a sheet film applicator<\/h2>\n<ul>\n<li>Sheet width, length and thickness, smallest to largest.<\/li>\n<li>Stainless grade and surface finish.<\/li>\n<li>Plain or printed film, one face or both.<\/li>\n<li>Sheets per shift.<\/li>\n<li>Manual feed or a feed conveyor.<\/li>\n<li>How covered sheets are stacked after the outfeed.<\/li>\n<\/ul>\n<h2 id=\"engineering-faq\">Engineering FAQ<\/h2>\n<p>Q: Why is the film printed SUS304?\nA: The print marks the steel grade on every sheet, so it can be identified after cutting. Your own print or logo can be used.<\/p>\n<p>Q: Is the sheet fed by hand?\nA: The sheet is laid on the table by hand and guided into the entry rollers. The powered rollers then take over and draw the material smoothly through the lamination zone.<\/p>\n<p>Q: How much film does each sheet use?\nA: Its length plus the gap to the next sheet. Our 2,000 mm example uses 2,050 mm.<\/p>\n<p>Q: Can both faces be filmed?\nA: A second film roll can be added for the lower face. Tell us if you need it.<\/p>\n<p>Q: Does it suit other metals?\nA: Yes. Aluminium and coated steel sheet are filmed the same way. Choose a film tack to suit the surface.<\/p>\n<h2 id=\"next-step\">Next step<\/h2>\n<p>We plan your sheet film applicator in three steps:<\/p>\n<ol>\n<li><strong>Submit your layout drawing<\/strong> with sheet sizes and grade to <strong>info@fhopepack.com<\/strong>.<\/li>\n<li><strong>Receive a proposal within 48 hours<\/strong>, with the film and roll plan.<\/li>\n<li><strong>Book a site survey<\/strong> to check the feed and stacking layout.<\/li>\n<\/ol>\n<h2 id=\"related-reading\">Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/Aluminum\/aluminum-profile-applicator.html\">Automatic aluminum profile protective film applicator<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/aluminum-profile-packing-line\/\">Aluminum profile packing line and surface taping systems<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-protective-foil-application-on-sheets\/\">Video: automatic protective foil application on sheets<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-cutting-of-film-covering-machine-on-sheets\/\">Video: automatic cutting of film covering machine on sheets<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/Automatic-Strapping-Machine\/\">Automatic strapping machines<\/a><\/li>\n<\/ul>\n<h2 id=\"sources\">Sources<\/h2>\n<ul>\n<li>Machine technical specification: FHOPE engineering team, 2026-10-04<\/li>\n<li>Automatic profile film sticking and cutting parameters: <a href=\"https:\/\/www.fhopepack.com\/Aluminum\/aluminum-profile-applicator.html\">Automatic aluminum profile protective film applicator<\/a><\/li>\n<li>Packing line equipment classification: <a href=\"https:\/\/www.fhopepack.com\/aluminum-profile-packing-line\/\">Aluminum profile packing line family<\/a><\/li>\n<li>Film consumption calculation: engineering worked example, illustrative values<\/li>\n<li>Safety and risk assessment standards: <a href=\"https:\/\/www.iso.org\/standard\/51528.html\">ISO 12100:2010<\/a>, <a href=\"https:\/\/www.nen.nl\/en\/nen-en-415-10-2014-en-191845\">EN 415-10:2014<\/a><\/li>\n<\/ul>\n<p><strong>Last reviewed:<\/strong> 2026-10-04<\/p>\n<p><strong>Last updated:<\/strong> 2026-10-29<\/p>","protected":false},"excerpt":{"rendered":"<p>Executive summary Stainless steel sheet is vulnerable to surface scratching and abrasion between the rolling mill and the fabrication facility, requiring its primary face to be covered with a self-adhesive protective film.
