Magnetic Core Prewound Sideless Bobbins keep the bobbin thread from backlashing in the bobbin case, which causes thread nesting on the bottom side of embroidered fabrics.*

  • Please remove any circular perforated backlash spring from inside your bobbin case when using Magna Core bobbins, so they have better contact with your metal bobbin case. (Remove perforated flat backlash spring from inside metal rotary bobbin cases when using magnetic bobbins to stop the bobbin from turning after machine stops. Magnetic core bobbins need better contact with bobbin case. ).
  • Fil-Tec's revolutionary magnetic core embroidery bobbin is the only bobbin specifically designed to sew without tension variation throughout the entire bobbin. The magnetic core, combined with our advanced EB "crosslink" technology optimizes dynamic thread delivery to create consistent tension from beginning to end of each bobbin.

  • Uniform Tension Control
    Our patented magnetic core creates consistent delivery throughout the entire bobbin. No more interruptions for tension adjustments as your bobbin gets smaller. Magnetic core prevents backlash or over spin and eliminates the need for backlash springs.

  • Fewer Bobbin Changes
    Our magnetic core bobbin offers significantly more stitches per bobbin reducing defects and increasing productivity.

  • Clean Running
    Advanced EB cross-link technology reduces lint and residual build-up in the bobbin case and tension spring. The result is a more trouble-free bobbin
