Parts of Sewing Machine and Function

How to Set Sewing Machine parts

The Needle and Needle Plate

The needle is one of the most critical components of a sewing machine. It is responsible for piercing the fabric and creating stitches. The needle plate, also known as the throat plate, is a metal plate with a small hole through which the needle passes. It provides stability to the fabric during stitching and helps in guiding the fabric in a straight line.

The needle is responsible for creating stitches by passing through the fabric and forming loops.

The Presser Foot

The presser foot is a movable part that holds the fabric in place while stitching. It exerts pressure on the fabric, ensuring smooth and even feeding. Different types of presser feet are available for various sewing techniques, such as zipper foot, buttonhole foot, and blind hem foot.

  • The presser foot holds the fabric securely in place during sewing.
  • It applies pressure to ensure smooth and even stitching.

The Feed Dogs

The feed dogs are small, toothed mechanisms located beneath the needle plate. They move in an up-and-down motion, gripping the fabric and advancing it during sewing. The feed dogs ensure consistent fabric movement and prevent puckering or uneven stitches.

  • The feed dogs work in conjunction with the presser foot to move the fabric smoothly while sewing.
  • They help maintain a consistent stitch length and prevent fabric slippage.
  • The feed dogs can be adjusted or lowered to enable free-motion sewing or darning.

Bobbin and Bobbin Case

The bobbin is a small spool that holds the lower thread. It is placed in the bobbin case, which is inserted under the needle plate. The bobbin and bobbin case work together to form the lower thread tension and create stitches on the underside of the fabric.

The bobbin holds the lower thread and works together with the upper thread to create stitches. To set this part of sewing machine is the most important part of sewing machine.

Spool Pins and Thread Guides

Sewing machines have spool pins that hold the spools of thread. Thread guides are small metal or plastic pieces that guide the thread from the spool to the needle. Proper threading through the spool pins and thread guides ensures smooth thread flow and prevents tangling.

The spool pin secures the spool of thread and enables smooth unwinding during sewing.

Tension Discs

Tension discs control the tension of the upper thread. Adjusting the tension discs ensures balanced stitches with the right amount of tightness. Proper tension is crucial for achieving neat and even stitches.

  • The tension control affects the appearance and strength of the stitches.
  • Increasing the tension makes the stitches tighter, while decreasing it makes them looser.

Stitch Selector and Stitch Length Regulator

The stitch selector allows you to choose different types of stitches, such as straight stitch, zigzag stitch, or decorative stitches. The stitch length regulator controls the length of the stitches, varying from short to long stitches based on the sewing requirements.

Handwheel and Balance Wheel

The handwheel, located on the side of the sewing machine, allows manual control of the needle’s up-and-down motion. The balance wheel is larger and is used to manually raise or lower the needle when precision is required, such as when starting or ending a seam.

Reverse Stitch Lever

The reverse stitch lever enables the machine to sew in reverse. It creates backstitches, reinforcing the beginning and end of a seam to prevent unraveling.

Thread Cutter and Thread Trimmer

The thread cutter is a small blade attached to the machine that allows you to cut the thread after sewing. Some advanced machines also have a thread trimmer that automatically trims the thread close to the fabric.

Foot Pedal or Electronic Control

Sewing machines can be operated using a foot pedal or electronic control. The foot pedal, similar to a car pedal, regulates the machine’s speed. Electronic controls provide speed adjustment buttons, making it easier to control the sewing speed.

Bobbin Winder

The bobbin winder is a mechanism that winds thread onto the bobbin. It ensures that the bobbin is properly filled and ready for use.
