Kategori:

This 4420 double-needle sewing machine uses three feeding systems that work simultaneously:

  • Feed dog → feeds the fabric from underneath
  • Needle feed → helps pull and move the material forward
  • Walking foot / presser foot → presses and moves the material together with the feed mechanism

With this system, the upper and lower layers of material are less likely to shift, resulting in neater and more precise stitching, even when sewing very thick or multiple layers of material.
