BERNINA Stitch Regulator (BSR) #42

The BERNINA Stitch Regulator reacts to the movement of the fabric under the foot, controlling the speed of the needle during free-motion sewing (when the feed dog is down). The set stitch length is maintained, irrespective of the movement of the fabric. The result is absolutely even stitch formation. The BERNINA Stitch Regulator can do both straight and zigzag stitching depending on the sewing system used.
