A sewing machine looper, also known as a bent needle, is an essential component of a sewing machine. It is responsible for creating loops of thread that interlock with the spool thread to create sturdy seams and hems in a variety of fabrics. The looper, along with the straight needle, creates the two-thread stitching process used in most sewing machines.
There are several types of loops that can be created using a looper, including chain stitches and overlock stitches. Chain stitches are created when the looper and needle interlock the thread on one side of the fabric, while overlock stitches are created when the looper and needle interlock the thread on both sides of the fabric. These types of stitches are common in the construction of garments, upholstery, and other fabric-based items.
While there are a variety of looper types available, most modern sewing machines use either a serger or an overlock sewing machine. Sergers are ideal for creating finished edges on garments and are often used in industrial settings. Overlock sewing machines, on the other hand, are designed for home sewing use and can perform a variety of different stitches, including the overlock stitch, the flatlock stitch, and the blind hem stitch.
