Industrial Sewing machine feed dogs are metal teeth-like ridges that emerge from a hole in the throat plate of an industrial sewing machine. Feed dogs move as you sew, gripping the bottom Material to help it transport it through the sewing machine producing a high quality stitch.
The feed dogs are visible ust underneath the Industrial Sewing machine’s presser foot.
