How to Adjust the Tension on a Kenmore Bobbin

The bobbin can hold threads of varying thickness.

A bobbin is a metal or plastic piece of a sewing machine that feeds thread into the needle. The bobbin usually goes in a slot on the underside of the machine, and some machines also come with bobbin winders that fill the bobbins with thread for you. You can adjust the tension on a bobbin if the thread is not coming out quickly or loosely enough, or if it needs to be tightened.

Things You'll Need

• Flat-head screwdriver

Instructions

1. Insert the wound bobbin into the bobbin case. Pull the thread under the tension spring and out through the slot in the bobbin case.

2. Insert a flat-head screwdriver into the tension adjusting screw on the side of the bobbin case. Turn the screw clockwise to loosen the tension.

3. Turn the screw counterclockwise to tighten the tension. Stop turning the screw when the tension is at the level you want. Replace the bobbin case in the shuttle, sliding the bobbin prong into the shuttle slot.
