Two Basic Types Of Sewing Machine Bobbins
When replacing a bobbin in a Singer sewing machine, understanding the two basic types of bobbins is key. Singer sewing machines use either Class 15 or Class 66 bobbins. Class 66 is a larger bobbin and fits in machines made before the 1970s, while Class 15 bobbins fit in machines manufactured after the 1970s. Before purchasing a new bobbin, it is important to identify what type of bobbin the sewing machine requires for optimal performance.
Winding The Bobbin With Thread
Wind the bobbin with thread. This is done by using the winding arm on the sewing machine to spin the bobbin in a clockwise direction. The threaded spool should be placed in the spool pin and wound around the bobbin. Note thatt if the bobbin is wound too loosely or too tightly, it may become jammed or difficult to stitch.
Removing And Replacing The Bobbin
For Singer sewing machines, the bobbin is typically stored in a case located on the underside of the machine. To replace the bobbin, the user must first remove the old bobbin by opening the hinged door on the bottom of the machine and sliding out the case. Once the bobbin case is removed, insert the new bobbin in the same manner as the old one was inserted. The bobbin must be placed correctly to ensure that thread tension is correctly calibrated.
Aligning The Bobbin And Thread
The bobbin and thread must now be properly aligned. To do this, the spool of thread should be aligned on the spool pin and the thread should be pulled around the bobbin case and the tension spring. Once the threads are lined up, the bobbin should be reinforced with a few stitches. This will ensure the bobbin is firmly secured before sewing.
Checking Thread Tension
It is important to check the thread tension before continuing with the project. After threading the machine and winding the bobbin, the user should do a trial run to make sure that the tension of the thread is properly calibrated. If the tension is too loose or too tight, it can lead to problems with the stitching or jamming of the machine. To adjust thread tension, use the tension dial on the machine.
Ensuring Smooth Stitching
Once the bobbin has been replaced, the user should make sure their stitching is smooth by doing a few test runs. The needle must be in the up position and the presser foot lever should be lowered. After the first two or three stitches, the slack created from the bobbin should be pulled up. Continue stitching until the desired length is completed. Be sure to remove the needle after each project.
Maintaining The Bobbin
After replacing the bobbin in a Singer sewing machine, proper maintenance and care will help to keep the machine running smoothly. Lint and other debris can accumulate on the bobbin and cause it to jam. Regularly clean the bobbin area of the machine and check the bobbin tension once in a while. It is also important to replace bobbins with the correct type and not to overfill them with too much thread.
Fitting The Bobbing Correctly
The bobbin in a Singer sewing machine must be fitted correctly for optimal performance. To ensure this, use the same bobbin for all projects and make sure the bobbin is lined up properly when replacing it in the bobbin case. If a user has difficulty replacing the bobbin, they should check the bobbin case and see if it is dried out or damaged, as this may be preventing a proper fit.
Using The Right Size Bobbin
When replacing a bobbin in a Singer sewing machine, users must make sure their machine is using the right size bobbin. Class 15 bobbins are typically used in machines made after 1970, while Class 66 bobbins are found in sewing machines manufactured before 1970. Uiversal bobbins, which may fit multiple machine models, are also available and are a good choice if the user is not sure which bobbin type is required.
Cleaning The Bobbin Case
Regular cleaning of the bobbin case is important to ensure optimal performance. If the bobbin case is not cleaned properly, lint deposits and other debris can build up and damage the machine. To clean the bobbin case, use a cotton swab or soft brush, warm water and a mild detergent. Do not use abrasive materials or sharp objects as this can damage the case.
Avoiding Cross Threading
Cross threading can cause serious issues in a Singer sewing machine. To avoid this, the bobbin thread should be placed in the slots of the bobbin case correctly and the cover should be put on correctly. Once the cover is put back on, make sure to turn the knob clockwise until it is securely tightened.
Using The Right Stitch Length
Before sewing with a Singer sewing machine, the user should make sure that the stitch length is set correctly. Stitches should be neither too tight nor too loose, so users should experiment with different stitch settings until they find the one that works best. They can also adjust stitch width and length on the computer screen of the electronic sewing machine.
Understanding Bobbin Tension
Understanding proper bobbin tension is key to ensuring smooth stitching with a Singer sewing machine. Bobbin tension should be neither too tight nor too loose, as this can lead to problems with the stitching. If the bobbin appears to be too tight or too loose, the user can use the tension dial to adjust it to the proper setting.
Troubleshooting Sewing Problems
In some cases, problems with the machine may occur even after the bobbin has been replaced. If the stitching appears to be uneven or erratic, the bobbin tension may need to be recalibrated. It may also be necessary to clean or replace the needle if the machine appears to not be able to penetrate the fabric. If the machine is skipping stitches, the bobbin may be at fault and may need to be replaced with a new one.
