Automatic thread cutting is a sewing machine function that automatically cuts both the upper and lower threads at the end of sewing. The function is usually activated by pressing a button, which is often marked with a scissors symbol. After sewing is complete and the cutting is activated, the machine's mechanism cuts both threads close to the fabric. This eliminates the need to pull out long thread ends and manually cut them with scissors. Sewing is thus smoother and leaves a clean stitch appearance with short thread ends.
