No Looper thread Twining: The rotating part of the looper thread cam shaft is covered to prevent the looper thread from twining around the looper thread cam shaft. A V-shaped thread catcher has been installed on the looper thread cam bracket to easily clamp the looper thread, which is likely to twine around the cam.
