This type of sewing machine features a narrow, cylindrical workspace extending horizontally from the machine’s body. This unique configuration allows for circular or tubular items to be easily rotated around the cylinder, facilitating stitching in hard-to-reach areas. Examples include cuffs, sleeves, and boot tops. The design provides superior maneuverability and precision when working with cylindrical and three-dimensional projects.
The free arm configuration facilitates sewing closed circular items with greater ease and control compared to flatbed machines. Its invention revolutionized the production of specific goods, particularly within the footwear and apparel industries. This innovative approach to sewing streamlined the manufacturing process for various products, enabling higher quality construction and enhanced efficiency.
