The Fiber Guide is a spare part that is a critical component of a sewing machine’s thread delivery system. It is responsible for guiding the thread from the spool to the needle, ensuring that it is delivered smoothly and consistently during the stitching process.
The Fiber Guide typically consists of a small metal or plastic piece that is positioned near the spool of thread. It is designed to hold the thread in place and direct it towards the needle, reducing the risk of tangling or knotting.
If the Fiber Guide becomes worn or damaged, it can cause the thread to be delivered unevenly or not at all, resulting in poor-quality stitching or even thread breakage. In such cases, it may be necessary to replace the Fiber Guide with a new one.
