Overlock machines can create a variety of stitches, including 2-thread, 3-thread, 4-thread, and 5-thread stitches. Each stitch has different properties, such as the number of threads used. The general procedure for using a 2-thread, 3-thread, or 4-thread overlock machine is similar, but there are some differences in the way the machines are set up and operated, there are several types of overlock sewing machines available in the market.
What Is A 2-Thread Over-Lock Sewing Machine?
A 2-thread sewing machine is a type of serger or over-lock machine that uses two threads and one needle to create a secure and stretchy seam, that can be used on a wide range of fabrics, particularly lightweight fabrics like silk, chiffon, and jersey knit. How does an overlock sewing machine work, the machine’s cutting blade trims the fabric edges as it sews, which helps prevent fraying and creates a neat and professional finish.
