| Magna-Glide is a revolutionary improvement in embroidery bobbin technology designed to improve sewing quality, consistency and productivity. However, because of the unique core and yarn construction, the following are recommended during initial set-up:
-
REMOVE ANTI-BACKLASH SPRING:
Some embroiderers use anti-backlash or check springs inside the bobbin case when using conventional sided bobbins to stop any bobbin over-spin. This is not needed when running Magna-Glide bobbins as the magnetic bobbin core will prevent bobbin over-spin. In fact, anti-backlash or check springs placed in the bobbin case may damage the sideless bobbins
-
LOAD BOBBIN SO THAT IT TURNS CLOCKWISE:
The magnetic tip of the core must sit on the bottom of the bobbin case, as this is what will create the uniform draw-off tension from the beginning to the end of the bobbin.
-
SET THE BOBBIN TENSION:
Set the bobbin tension at 18-22 grams or do a drop test (bobbin case should drop about one inch when you hold the yarn and gently bounce the bobbin case up and down as if you had a yoyo in your hand).
