The Looper DFL is a spare part for a sewing machine that is a critical component of the machine’s overlock or serger mechanism. It is responsible for creating the loop that interlocks with the needle thread to create a secure stitch.
The Looper typically consists of a metal or plastic component that is positioned next to the needles and moves in synchronization with them. It is designed to thread the needle thread through the fabric and then create a loop that is caught by the looper thread. The two threads are then interlocked to create a secure stitch.
If the Looper becomes worn or damaged, it can cause the machine to produce poor-quality or incomplete stitches. In such cases, it may be necessary to replace the Looper with a new one.
