Each stage can become a weak point when processing delicate materials.<\/p>\n<p>The process starts with roll unwinding and pre-cutting, handled by the 92XTS, also available in a multilayer version. This is followed by blade or roller pleating. Next comes cross-cutting with edge bonding (94XTT-HM) to close the cylinder. Finally, the casting stage: the 101COMPACT for single end-cap and top-cap casting, or multi-station lines for high-speed production cycles.<\/p>\n<p><strong>The Soft Touch System for Delicate Materials<\/strong><\/p>\n<p>With PTFE membranes or nanofiber materials, the challenge is not cutting but controlling web tension during pleating. Too much tension can tear the material; too little can result in irregular pleats.<\/p>\n<p>The servo-driven 91XSPL pleating machine addresses this with the Soft Touch system. It adaptively controls web tension during material feed. It works with both single-layer and multilayer materials, without requiring continuous operator supervision.<\/p>\n<p><strong>Diameters and Heights Covered by the Range<\/strong><\/p>\n<p>The range covers diameters from 50 to 500 mm and heights from 50 to 1,200 mm. This range covers both compact cartridges for small dust extraction systems and large-format elements for industrial dust collectors.<\/p>\n<p>The most common applications include centralized dust extraction, machine tools, and metal and woodworking processes.<\/p>\n","protected":false},"featured_media":3321,"template":"","meta":{"_acf_changed":false,"content-type":""},"categoria-filtro":[68],"class_list":["post-3476","filtro","type-filtro","status-publish","has-post-thumbnail","hentry","categoria-filtro-air-gas"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.4 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Dust Filter Cartridge Production Machines | SPM<\/title>\n<meta name=\"description\" content=\"SPM production lines for dust filter cartridges: pleating, cylindrical closure, and PU casting.
