Built for Emblem & Patch Edging

• Dedicated emblem edge sewing machine – not a general-purpose serger.
• Produces a tight, decorative overedge stitch around emblems and patches, giving them a clean, finished border.
• Ideal for embroidered logos, uniform patches, sports team emblems, service badges, biker patches, fashion appliqués and promotional crests.
• Stitch formation is optimized so the edge looks even, compact and professional, ready for heat-seal backing, sew-on, or hook-and-loop applications.

Precise Control on Small, Curved Shapes

• Designed to handle small, irregular and curved shapes commonly found in badges and patches.
• The machine geometry makes it easy to follow tight curves and corners while maintaining consistent coverage around the entire perimeter.
• Operators can run single emblems or small batches with repeatable, consistent results.
