The single threads to be twisted are taken from two or more feed bobbins. These are inserted into each other and arranged on the stationary bobbin chuck. A hollow cylinder serves as a seating for the feed bobbins inserted into each other, and is mounted on the bobbin chuck by means of centering. The hollow cylinder has a ring flange on its lower edge to support the feed bobbins. The ring flange has a number of ring-shaped centering steps corresponding to the number of feed bobbins which can be mounted. |
