A double needle sewing machine is a specialized sewing device that accommodates two needles on a single needle bar. This configuration allows the machine to stitch two parallel lines of thread at the same time. The dual capability not only speeds up the sewing process but also produces a more professional finish on various fabrics. The double needle operates with a single bobbin thread, which means that while two needle threads are being stitched, only one layer of bobbin thread is utilized, creating a distinctive look in the finished product.
The versatility of an overlocker extends beyond seam finishing. Many models come equipped with the capability to create various stitch types, including rolled hems and flatlock stitches. A rolled hem is perfect for delicate fabrics such as chiffon and silk, adding a refined edge without bulk. On the other hand, flatlock stitches are excellent for joining fabrics, especially in activewear, as they provide a comfortable, minimal-seam finish.
