The Thread Knife FL is a spare part for a sewing machine that is a critical component of the machine’s cutting mechanism. It is responsible for trimming excess thread or fabric from the edge of the fabric after stitching.
The Thread Knife FL typically consists of a sharp metal blade that is positioned next to the fabric being stitched. It is designed to move up and down in synchronization with the needle to trim excess thread or fabric from the edge of the fabric.
If the Thread Knife FL becomes dull or damaged, it can cause the machine to produce poor-quality or incomplete stitches or fail to trim the excess thread or fabric. In such cases, it may be necessary to replace the Thread Knife FL with a new one.
