Middle thread guide with thread take-up spring <PAT>

The thread take-up spring picks up excess thread and stabilizes the balance of upper and lower threads at high speed and improves thread tension. Thread breakage due to extra fine satin stitches (2mm or less), needle tip or thread untwisting, etc. has been reduced by 30 - 50% (compared with our conventional specification), and productivity has been drastically improved.

The thread take-up spring draws the thread closer to the needle and has improved the response to thread take up timing.
