The Roller Foot is designed to feed slippery fabrics such as silk, leather and velvet. The knurled rollers on the foot provide pressure for fabrics between foot and feed dogs allowing various slippery fabrics to be sewn easily and smoothly.
The Roller Foot is commonly used with a straight stitch or zig zag stitch. It can also be used with other utility and decorative stitches.
Suitable only for machines that have the front loading bobbin system as shown here.
