The spool disk is used to cap the thread spool on the horizontal spool pin of the Bernina classic domestic sewing machines. It prevents the thread from catching in the grooves of the thread spool and keeps the thread winding off the spool in an orderly fashion.
This Bernina spool retaining disc medium slides onto your horizontal Bernina spool peg and holds the thread in place. We recommend that you slide the spool retaining disc on as shown in the photo and leave a very small gap between the thread and the disc.
Always also remember that if your reel of thread has a nick, or ‘grip’ to hold the thread, it must be placed away from the retaining disc. This will prevent thread catching as it peels off.
