Inserting a bobbin is a fundamental step in the operation of many sewing machines. The bobbin is a small spool that holds the thread used for the lower part of the stitch. Without a properly inserted bobbin, the machine will not be able to create a complete stitch, and the fabric will not be sewn together correctly.
The process of inserting a bobbin varies depending on the type of sewing machine being used. However, there are some general steps that apply to most machines. Once the bobbin is inserted correctly, it is important to wind the thread around the bobbin winder and through the tension discs in order to ensure that the thread is properly tensioned. This will help to prevent the thread from breaking or becoming tangled during sewing.
