Functions Of Kenmore 385 Bobbin
Understanding the functions of the bobbin in a Kenmore sewing machine model 385 is essential for efficient stitching and overall machine operation.
Here are seven critical functions of the Kenmore bobbin:
Thread Storage
The primary function of the bobbin is to store the lower thread that will be used for stitching. It holds the thread in place and ensures a continuous supply during sewing.
Thread Tension Regulation
The bobbin helps regulate the tension of the lower thread, working with the upper thread tension to achieve balanced stitching. Proper tension ensures neat and even stitches.
Thread Delivery
As the sewing machine operates, the bobbin releases the lower thread in synchronization with the upper thread, allowing for the formation of stitches. It delivers the thread to the needle area for stitching.
Thread Locking
The bobbin thread is crucial in securing stitches by interlocking with the upper thread in the fabric layers. This locking mechanism creates durable and stable seams.
Understitching
The bobbin thread is often used for understitching, a technique where the lower thread is stitched close to the seam allowance to prevent fabric layers from rolling or shifting.
Bobbin Winding
Before sewing, the bobbin needs to be wound with thread. Many Kenmore 385 models feature a built-in bobbin winding mechanism for convenient and quick winding.
Bobbin Case Placement
The bobbin is housed within the bobbin case and inserted into the sewing machine. Proper bobbin case placement and insertion are essential for smooth operation and stitch formation.
