With a generous 750mm of free space under the arm and powerful unison-feed that provides a maximum stitch length of 10mm, the machine delivers outstanding productivity when sewing heavy materials such as tents, sheets and mattresses. The bobbin winder is installed at the front face of the arm for easy operation. Since the machine incorporates a vertical-axis large hook, the frequency of bobbin thread replacement is reduced, further increasing efficiency.
