Pre Wound bobbins (Nebs or Robison Anton)

Pre-wound bobbins have been "approved" by Husqvarna Viking for several years, going back to the Designer I. They have to be the correct size, and there are some drawbacks to using them. The tension is "different". It looks the same on the top of the fabric, but the back, if you change from a pre-wound bobbin to a "self" wound bobbin in the middle of the embroidery, you will find it looks different on the back. There are also different pre-wound bobbins. Some are nylon/polyester and some are cotton. Again, they will give different tension results. Because they can be put in "upside down", you need to be sure the thread is going in the correct direction when you insert them. There is a document on www.husqvarnaviking.com, USA, "Tips and Hints" addressing the way to have a GREAT, successful experience with pre-wound bobbins.

The other thing that can happen is that the bobbin empty sensor won't go off right away. Usually, even if the bobbin empty sensor doesn't read the empty bobbin, the top thread "broken" comes up since a stitch is no longer being formed.

Another side effect is that because of the thin, fine thread, the bobbin thread may not be picked up when touching FIX, to baste. You can "get around this" by pulling out a bit of a longer thread tail, or taking a few stitches of the design, then touching FIX.

These results are because pre-wound bobbins are made to fit a variety of different machines, not just Husqvarna Viking machines. If you are bothered by some of the side effects of pre-wound bobbins, they can be avoided by winding bobbin thread on the Husqvarna Viking bobbins made for your machine.
