Crochet Patent Needles – for Comez & Karl Mayer | LONGTEX

•  Crochet patent needles are specialised latch needles used in crochet knitting machines (also known as warp crochet machines) to produce narrow-width fabrics, laces, trimmings, elastic bands, and medical textiles. These machines combine warp knitting principles with weft insertion, creating fabrics with excellent dimensional stability and decorative stitch effects.
• Our crochet patent needles are manufactured from high-grade alloy steel with advanced vacuum heat treatment, delivering optimal hardness (60–64 HRC) and superior wear resistance. Available in various gauges and butt configurations to suit all major crochet machine brands including Karl Mayer (ex-Comez), Comez, and Jakob Müller. Precision-ground hook, latch, and butt geometries ensure smooth high-speed operation, consistent stitch formation, and extended service life.
• Applications include lingerie trimmings, narrow elastic fabrics, medical bandages, shoe uppers, technical tapes, and decorative laces.
