The Role of the Bobbin in a Sewing Machine

The bobbin holds the lower thread used during the sewing process. As the needle carries the upper thread toward the hook, the machine's mechanism interlocks the two threads to form each stitch.

Therefore, a warped or improper bobbin can cause problems such as irregular stitches, thread jams, noise in the hook area, or difficulties while sewing.

Using a coil of the appropriate type helps maintain uniform movement within the coil system and contributes to the machine's proper operation.

When should you replace a coil?

With frequent use, the reels may become dented, misshapen, or worn. In addition, an incorrect reel may not fit properly inside the machine.

It is recommended that you inspect or replace the coil when problems such as the following occur:

• Coil is bent or deformed.
• Irregular transfer within the system.
• Frequent thread jams.
• Unusual noise coming from the lower area.
• Difficulty winding the thread properly.
• Original coil is missing or damaged.
