These
magnetic core embroidery bobbins are the only bobbin specifically
designed to sew without tension variation throughout the entire
bobbin. The magnetic core, combined with advanced EB "cross-link"
technology optimizes dynamic thread delivery to create consistent
tension from beginning to end of each bobbin.

Uniform Tension Control - The
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 check springs. Remove
anti-backlash (check springs) from bobbin case prior to using the
Fil-Tec magnetic embroidery bobbin.

Fewer Bobbin Changes - The 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.

High Quality Yarn
- Fil-Tec uses only the finest quality, high tenacity
polyester yarns to make it patented magnetic core embroidery
bobbin.
