The heavy-duty sewing machine was manufactured with strong components that will outlast other types of sewing machines because of the machine's ability to stitch multiple layers of denim multiple times. It has an all-metal frame design, a reinforced frame on the feed mechanism, and a heavy-duty motor that is designed to provide a high amount of torque.
The machine has a walking foot that works in conjunction with the feed dogs to assist in pulling the heavy layers of material evenly and with very little effort. In addition to all of these features, the machine has an adjustable presser foot, allowing it to accommodate fabric weights from very light, such as silk, to very heavy, such as denim.
