  • Patent number: 4274350
    Abstract: The attachment is primarily used as a replacement for the conventional presser foot typically employed on an industrial sewing machine, and is in particular useful when stitching multiple layer fabrics having synthetic backings. The attachment is for pressing the fabric being stitched against parallel arranged feed dogs and includes a wheel assembly frame supported from one end of a presser arm which is, in turn, pivotally supported at its other end from the machine. The wheel assembly supports a wheel mounted for rotation about a substantially horizontal axis and preferably of a yieldable rubber or rubber-like material that overlies one of the feed dogs of the sewing machine, and a presser foot mounted beside the wheel having a lower pressing surface and overlying a second feed dog of the sewing machine.
