Lower Looper for Pfaff Overlock (Ref. 98-784083-60/600)

The lower looper is the hook-shaped mechanism that carries the bottom thread while the needles pierce the fabric and form the overlock stitch. It is through its curves and guides that the thread is correctly tensioned and intertwined, ensuring uniform and elastic stitches for finishing edges.

When the lower looper wears out (due to lint build-up, incorrect alignment, or intensive use), it creates skipped stitches, thread breakage, and fabric snags that spoil the professional finish. Replacing the looper is the reliable solution to regain precision and fluidity in forming overlock stitches.
