PATENTS · IP PORTFOLIO
Every improvement,
written down as a verifiable patent
Thirty granted patents across four technical directions: synchronized rotation mechanisms, pattern-stitch control, automated loading and production lines, and temperature-regulated sewing. Each one can be checked by its publication number in the CNIPA public database.
PORTFOLIO
From rotary hook to production line
Our patents are not a numbers game: synchronized hook and needle-bar rotation stabilises stitches on heavy and three-dimensional work, automated handling and lines deliver batch consistency, and temperature-regulated sewing covers hot-melt and high-friction processes.
