Another benefit is the ease of adjustment. The single needle lock stitch can be easily modified in terms of stitch length and tension, allowing sewers to experiment and achieve the desired look and functionality. This adaptability is valuable, especially when working with different fabrics and project requirements.
The design of high-speed overlock machines features multiple needles and loopers that work in sync to create a serged edge. This method not only prevents fraying but also produces a clean, professional finish, essential for woven and knit fabrics. The capability to sew different types of stitches, including rolled hems and flatlock seams, further increases the versatility of these machines, making them suitable for a wide range of sewing applications, from fashion design to home decor.
