How to Place a Bobbin in a Sewing Machine
Having a sewing machine with a correctly placed bobbin is essential in producing neat and even stitches. Although each sewing machine varies, the steps below are general guidelines to help you place a bobbin in yours:
Firstly, the right side plate should be opened. The bobbin case sits directly on top of the needle plate which comes with a diagram to explain where to place the bobbin case. On models where the side plate also holds the motor, two or three screws may need to be removed prior to it opening.
Secondly, the bobbin is usually placed into the bobbin case in the anti-clockwise direction. The bobbin thread should then be led over the one of the little grooves, the bobbin should then be held and the thread pulled downward through a small hole that is visibly shown in the case.
Thirdly, the case should now be checked using the diagram above to ensure that it’s properly aligned. It should then be placed back into the machine with the thread going downwards in a clockwise direction.
Fourthly, the right side plate should now be firmly closed. On certain models there are various types of latches used, so it is important to securely fasten the plate so that it is accurately placed in the machine.
Fifthly, place the spool of thread onto the spool pin, or if the model has two, place it onto the other spindle located above the needle plate. Pull the top thread so it passes through the indicated slot.
Finally, pull up the bobbin thread which is located below the needle plate. By slightly turning the flywheel, the needle should be lowered capturing the bobbin thread to the top thread. Once the threads are correctly in place, the sewing machine should be ready for use.
Types of Bobbins
Bobbins come in a wide variety of shapes and sizes, depending on the sewing machine. Choosing one that is wrong can cause issues with the machine such as timing, poor stitch formation or tension problems. It is therefore important to ensure that you are buying the right bobbin for your machine. General tips when purchasing one, is to check its size, measurements and also its material type.
Additionally, when servicing a sewing machine, bobbin cases should be oiled every now and then to avoid any unwanted rust. One should be careful not to over-oil the bobbin case, which can lead to uneven stitches. Moreover, a worn-out bobbin should be replaced instantly to avoid any more damage to the sewing machine.
Cleaning the Machine
It is essential to clean and maintain a sewing machine regularly. This process will ensure that its parts are working smoothly and extend its lifespan. Firstly, remove the bobbin case and any dirt inside the machine. A vacuum cleaner can be used to carefully remove any dust and dirt inside the machine. Ensure that the bobbin area has been thoroughly cleaned.
Secondly, the top cover plate should be removed and any dust swept away with a duster and brush. Any lint that has built up on the surface of the needle plate can be removed with a spatula, adhesive or needle plate cleaning tool provided by the manufacturer.
Thirdly, oil the moving parts of the machine where appropriate. When oiling the needle bar, raise it to its highest point and lightly oil up and down the bar a few times to ensure maximum lubrication. With the latest machines, oil is not needed as regularly as before; however it is best to use a good quality, none sedimentary oil.
Finally, some sewing machines, mostly the electronic models have anti-static built into them. Therefore drying out the machine with a hairdryer or wiping with a damp cloth can damage it, especially the board. For best practice, take the machine to a licensed service center to properly clean.
Thread Tension
Thread tension is an important aspect when it comes to producing neat and professional looking stitches. Through trial and error, one can finally figure out how tight or loose the threads need to be. Generally, the two threads should be equally as tight, meaning both should be visible from the top.
If the thread tension is too tight, the thread may break, looping on the underside fabric, become distorted and pulled, or the bobbin thread may move to the surface of the fabric. On the other hand, if the thread tension is too loose, the stitches will be loose and not secure.
For best practice, the upper thread tension should be adjusted first then the lower thread tension. This is because the top thread determines how tightly the bobbin thread is pulled up through the fabric, making it visible at the top.
Using the thread tension dial, one can set the tension by changing the numbers. However, it is best to use the machine’s manual as a reference when adjusting the thread tension as it can depend on the brand and type of machine.
Using the Foot Pedal
Using the sewing machine’s foot pedal is necessary and useful in normal sewing speed. Every time that you lower the presser foot onto the fabric to sew and then raise it when testing, you should be using the foot pedal. This helps you control the speed at which the needle moves and makes sewing more comfortable.
Solely relying on the start and stop button on the machine can create an imbalance between the speed at which the needle moves and the speed at which the fabric feeds. This in turn can result in uneven stitches, puckering or pleating of the fabric.
Before beginning to sew, it is important to get the right pedal resistance. To adjust the foot pedal tension one must first locate the screw that sits at the bottom of the housing. To apply tension, turn the screw clockwise, rotating it should also enable one to make other adjustments depending on the type of sewing machine.
Hence, in order to ensure one is producing clean and strong stitches, it is important to learn how to place a bobbin correctly. Additionally, being familiar with the thread tension, cleaning the machine and also using the foot pedal correctly, can help make sewing a much easier and enjoyable experience.
