Understanding Bobbin Types
Bobbins are essential components of sewing machines, holding the thread that forms the bottom half of the stitch. Different Singer sewing machines may require specific bobbin types, so understanding their variations is crucial.
There are two primary types of bobbins used in Singer sewing machines:
| Type | Description |
|---|---|
| Class 15 | Compatible with older Singer sewing machines manufactured before the 1950s. They are typically made of metal and have a small, rounded shape with a single hole for the thread. |
| Class 66 | Used in more modern Singer sewing machines manufactured after the 1950s. These bobbins are typically made of plastic and feature a larger, oval shape with two holes, one for the thread and one for a spring-loaded tension disc. |
In addition to these two main types, some Singer sewing machines may use specialized bobbins designed for specific purposes, such as embroidery or quilting. It is always recommended to consult the user manual or the manufacturer’s website to confirm the correct bobbin type for your particular sewing machine.
