What Is a Heavy-Duty Upholstery Sewing Machine?

One of the primary functions of an overlocker is to sew and trim fabric edges simultaneously. This capability allows for quick and efficient sewing, significantly reducing the time it takes to finish a garment. When working with woven fabrics, the overlocker can quickly create clean and professional seams that do not fray, ensuring the longevity of clothing items. Additionally, the overlocking process often features a rolled hem function, which is particularly useful for lightweight and delicate materials like chiffon or organza, providing a neat finish without the bulk of a traditional hem.

While the double needle sewing machine offers fantastic possibilities, there are a few limitations to consider. For instance, zigzag stitching and other decorative stitches are typically not possible with a double needle, as they require a single needle setup. Additionally, the machine will not sew through multiple layers of thick fabric effectively, so it’s best to reserve double needle techniques for lighter to medium-weight materials.
