Threading the bobbin on a Singer stitching machine is a basic step in getting ready to stitch. The bobbin is a small, cylindrical spool that holds the decrease thread in a stitching machine. When the needle pierces the material, it creates a loop of higher thread on the highest of the material and a loop of decrease thread on the underside. These loops interlock to kind a sew.
There are a number of advantages to threading the bobbin appropriately. First, it ensures that the machine will sew easily and with out jamming. Second, it helps to stop skipped stitches, which might happen when the bobbin thread is just not correctly tensioned. Third, it might assist to increase the lifetime of the bobbin and the stitching machine itself.
