Final answer:
The two major parts of a serger that are not found on a sewing machine are loopers and blades. A serger has loopers which create thread loops on the fabric edge and blades for trimming the fabric. A sewing machine, on the other hand, has needles, bobbins, presser foot, feed dogs, spool pins, and tension disks.
Step-by-step explanation:
The two major parts of a serger that are not found on a sewing machine are loopers and blades.
A serger, also known as an overlock machine, is a specialized sewing machine that is used to finish seams and edges of fabric. It has two loopers, which are responsible for creating the thread loops on the edge of the fabric, and two blades, which trim the fabric as it is being serged.
On the other hand, a sewing machine typically has needles and bobbins for stitching fabric, a presser foot and feed dogs for fabric control, and spool pins and tension disks for thread management.
