Mechanical Parts of Kenmore Sewing Machines
The mechanical parts form the core of the sewing machine’s operation. These include:
1. Needle Assembly
The needle is the most visible part of the sewing process. It pierces the fabric and interacts with the bobbin thread to form stitches. Key components include:
- Needles (various sizes and types depending on fabric)
- Needle clamp (holds the needle securely)
- Needle plate (supports fabric and needle area)
2. Feed Dog System
The feed dogs are a set of ridged metal teeth that move fabric through the sewing machine in a controlled manner. They are essential for consistent stitch formation.
3. Presser Foot
The presser foot holds fabric flat against the feed dogs. Different types of presser feet are available for various sewing techniques, such as zipper feet, quilting feet, and embroidery feet.
4. Tension Discs
These control the tension of the upper thread, which is critical for balanced stitches. Proper tension prevents issues like puckering or skipped stitches.
5. Hand Wheel and Stitch Selector
The hand wheel manually moves the needle up and down, and the stitch selector allows choosing different stitch patterns.
Electrical and Motor Parts
Modern Kenmore sewing machines incorporate electrical components that automate many functions:
- Motor: Powers the machine’s movement.
- Foot Pedal: Controls the sewing speed.
- Circuit Boards: Manage electronic functions and stitch patterns.
- Power Switch and Wiring: Connect the machine to electricity and control power flow.
Regular inspection and maintenance of these parts ensure safe and efficient operation.
Needle and Threading Components
Proper threading and needle maintenance are vital for quality sewing:
- Needles: Need to be replaced regularly to avoid skipped stitches or fabric damage.
- Thread Guides: Direct the thread from the spool to the needle.
- Tension Regulator: Adjusts the tension for different fabrics and threads.
Bobbin and Bobbin Case
The bobbin supplies the lower thread in sewing:
- Bobbin: Comes in various sizes, usually Class 15 or Class 66, depending on the machine.
- Bobbin Case: Holds the bobbin and maintains tension for even stitches.
- Bobbin Winder: Used to wind thread onto the bobbin from a spool.
Properly threading and maintaining the bobbin system prevents issues like uneven stitches or thread jams.
Drive and Motor Components
These parts convert electrical energy into mechanical movement:
- Drive Belt: Transfers power from the motor to the hand wheel or gears.
- Gears and Cam Systems: Control stitch formation and machine movement.
- Motor Brushings: Wear over time and may need replacement.
Ensuring these parts are in good condition is crucial for smooth sewing operation.
