Adjusting the tension on your Singer sewing machine is crucial for achieving balanced and professional-looking stitches. Here's how you can typically adjust the tension, based on common Singer models and insights from the reference:
The reference mentions that for the Singer Simple 3337 model, the tension dial is typically adjusted between 3, 4, and 5. Most of the time, the user keeps it at 4.
Here's a general approach to adjusting the tension:
-
Locate the Tension Dial: This is usually a numbered dial located near the top of the machine, often around the needle area.
-
Understanding Tension:
- Balanced Tension: The ideal stitch has the top and bobbin threads locking together evenly within the fabric.
- Top Thread Too Tight: If the bobbin thread is visible on the top side of the fabric, the top tension is too tight.
- Top Thread Too Loose: If the top thread is visible on the underside of the fabric, the top tension is too loose.
-
Adjusting the Tension:
- To tighten the top tension, increase the number on the dial (e.g., from 3 to 4).
- To loosen the top tension, decrease the number on the dial (e.g., from 4 to 3).
-
Testing: After each adjustment, sew a test line on a scrap of the same fabric you'll be using for your project. Examine the stitches to see if the tension is balanced. Continue adjusting until you achieve a balanced stitch.
-
Bobbin Tension (Less Common Adjustment): In some cases, you might need to adjust the bobbin tension, but this is less common. It usually involves a small screw on the bobbin case. Only adjust this if you've exhausted all options with the top tension and are still experiencing issues. Make very small adjustments to the bobbin tension screw.
Example:
Let's say you're using a Singer Simple 3337, and you notice that the bobbin thread is showing on the top of your fabric.
- Problem: Top tension is too tight.
- Solution: Decrease the number on the tension dial. If it's currently at 4, try setting it to 3.
- Test: Sew a test line and examine the stitches. Adjust further if needed.
