Pfaff Invisible Zipper Foot Snap-On - Part 820474096

Replacement Invisible Zipper Foot for Pfaff Sewing Machines

Achieve professional, concealed zipper installations with this specialized invisible zipper foot designed for Pfaff sewing machines. Part number 820474096 is a replacement snap-on presser foot that creates clean, discreet zipper insertions with stitching hidden within the seam for a polished, professional finish.

What This Foot Does

The Invisible Zipper Foot is a specialized presser foot used to insert invisible (concealed) zippers with a professional, clean finish, ensuring the stitching is discreetly hidden within the seam. Unlike regular zipper feet, this foot is specifically designed to work with invisible zippers where the zipper teeth are hidden on the wrong side of the fabric.

Unique Groove Design: The foot has unique grooves on its underside that roll back the zipper coils, allowing the needle to stitch as close to the teeth as possible. This creates the invisible effect where the zipper disappears into the seam.

Professional Results: By guiding the zipper coils through the grooves while stitching, you achieve a clean, professional installation where the zipper is completely concealed from the outside of the garment.

Dual Grooves: The foot features both left and right grooves, allowing you to sew each side of the invisible zipper with precision and consistency.

How to Use the Invisible Zipper Foot

1. Prepare the Fabric and Zipper: Mark the zipper's length on the fabric. The zipper should be slightly longer than this mark. Gently flatten the zipper coil without ironing it.
2. Attach the Foot and Set Stitch: Snap on the Pfaff Invisible Zipper Foot and set your machine to a straight stitch with a center needle position, using a stitch length between 2.5 and 3.0 mm.
3. Sew the Right Side: Place the right side of the zipper tape on the right side of the fabric opening, aligning the coil with the seam line. Position the coil in the right groove of the foot and stitch from the top, stopping at the marked endpoint.
4. Sew the Left Side: Attach the second zipper tape to the left side of the fabric, ensuring the tops of the coils are level. Place the coil in the left groove of the foot and sew from the top down to the endpoint.
5. Finish the Seam: Switch to a standard zipper foot and sew the seam below the zipper, stitching close to the end of the zipper seams.
6. Press: Press the finished seam open for a professional finish.

Why Use an Invisible Zipper Foot?

Invisible zippers create the most professional, polished look for garments because the zipper completely disappears into the seam. However, they require a specialized foot to install correctly. The grooves on this foot are essential for rolling back the zipper coils so you can stitch as close to the teeth as possible, which is what creates the invisible effect. Without this specialized foot, achieving a truly invisible zipper installation is nearly impossible.

Create professional, concealed zipper installations with this reliable replacement invisible zipper foot designed for Pfaff sewing machines.
