Heavy-duty sewing machines, designed for working with denim, offer industrial performance combined with convenient controls for the user. Constructed from metal, heavy-duty sewing machines have a reinforced frame to reduce vibration when sewing at high speeds; this makes it possible for the machine to sew evenly on heavy fabrics.
To help the sewing machine sew even layers of denim, canvas, or faux leather, it comes with an in-built walking foot, a presser foot that can be adjusted to different pressures, and feed dogs that are strong enough to help move multiple layers of fabric through the sewing machine. This type of machine is capable of performing many functions, including straight stitches, zigzag stitches, and several utility stitches.
