Presser Foot with Rings. Industrial presser foot with PTFE (Teflon) coating and guiding rings, designed for sewing difficult or coated fabrics. It improves fabric transport when working on multi-layered projects such as quilts, ovata-filled blankets, thick textiles, or eco leather. The non-stick surface reduces friction, protects the material, and ensures consistent stitch quality. Compatible with industrial lockstitch machines with bottom feed, including Juki, Siruba, Pfaff, Texi, Brother, Dürkopp, and others.
