The „anti-wedge“ ring


This was the first high-performance ring. It is still on sale. Compared with the previously customary ring shape, it features a flange with a flared inside surface and is flattened off considerably on top. This change in shape enabled a  ring traveler with a low center of gravity and precisely adjusted arc (elliptical traveler) to be used and thus also permitted operation at higher speeds. Anti-wedge rings and elliptical travelers belong together and should only be used in combination. Since the space for the yarn passage is limited, this combination can only be used for fine and medium count yarns.
