* Moving the fabric: The feed dog consists of small, pointed teeth that grip the fabric and move it forward with each stitch. This ensures smooth and consistent fabric movement, preventing puckering or bunching.
* Consistent stitch length: By moving the fabric in a controlled manner, the feed dog allows for consistent stitch lengths.
* Preventing skipped stitches: The feed dog prevents the fabric from slipping or moving backward during sewing, which could result in skipped stitches.
* Feeding multiple layers: The feed dog can handle multiple layers of fabric, allowing for sewing thicker materials.
* Adjustable pressure: The feed dog pressure can be adjusted depending on the type of fabric being sewn. This allows for optimal feeding and prevents damaging delicate fabrics.
In short, the feed dog plays a vital role in achieving high-quality sewing by ensuring the fabric is moved smoothly, consistently, and securely through the machine.
