In a lockstitch sewing machine, various parts contribute to its functionality. Here is a list identifying the numbered parts:
1. Needle: The needle is a slender, pointed metal tool that carries the upper thread through the fabric.
2. Presser Foot: It is a mechanism that holds the fabric in place while sewing and ensures even feeding of the fabric.
3. Feed Dogs: These are metal teeth-like mechanisms under the presser foot that move the fabric forward during sewing.
Some other parts are:
4. Thread Take-Up Lever: This component removes excess slack in the thread and regulates the thread tension.
5. Tension Discs: Found within the machine, these discs control the tension of the upper thread.
6. Bobbin Case: The bobbin case holds the bobbin, which carries the lower thread used in lockstitch formation.
7. Bobbin: A small, spool-shaped object that holds the lower thread.
8. Needle Plate: This is a metal plate with a hole for the needle to pass through. It provides support to the fabric during sewing.
9. Balance Wheel: Also known as the handwheel, it manually controls the movement of the machine and the position of the needle.
10. Stitch Length Regulator: This allows adjustment of the stitch length according to the sewing requirements.
