Why the bobbin thread is confused: the reasons

The confusion of the lower threads in the sewing machine is the most common problem for embroiderers. It happens for various reasons, but it always causes inconvenience - when you sew a bunch of threads appears and the needle gets stuck in them. Why is this happening and how to fix the situation?

Why the bobbin thread is confused: the reasons

The bottom thread in any sewing machine is confused because of:

• improper needle in a machine pulling thread and material (it should not be blunt or too wide);
• poor staff that is not calibrated in the area of ​​the teeth or jumper;
• dull teeth on a rail;
• improper operation of the rack, its sudden movement, when the needle has already pierced the fabric and began to work;
• improper operation of the pressure spring as a result of damage or old age;
• broken bottom of the foot;
• defect on the lower part of the foot;

• loose bobbins to the structure;
• improperly installed friction washer on the flywheel;
• small or excessively strong thread tension. Each fabric must have its own tension;
• breakage of the bobbin thread, which begins to constantly wind around the entire part of the bobbin and stop looping the fabric;
• improper holes on the needle plate, which interferes with the needle's work on the fabric;
• incorrectly threaded thread;
• unusual threads. Usually, the right-twisted appearance of sewing threads leads to confusion;
• non-standard spools, threads or bobbins.

Bobbins are required to feed the thread from the creel and pull them up. Each of them has a cone shape and is ideal for such work. When operating a conventional machine, where the thread is fed left or right, the bobbin becomes uncomfortable, because it is heavy and too wide in diameter.

Also, the reasons for confusion lie in the fanatical sipping or pushing of the fabric with your hand - this activity will not only break the thread, but also lead to damage to the processed fabric. In this case, it is recommended to make a test stitch on a piece of material before each sewing session in order to select the desired pace of sipping the fabric.

Reference! Naturally, there are other reasons for the confusion of threads in the sewing machine, which sometimes occur while working with it. Basically, this concerns the wear of parts and breakdowns in the internal components of the machine, for example, a shuttle, needle bar or control unit.

How to adjust the bobbin thread yourself

Incorrectly threaded thread is the most common cause of a lump of thread when working with a sewing machine. The first thing to do: check the fueling is correct. This applies not only to the upper, but also to the lower thread. Refill both according to the instructions for the typewriter and try again to work with the device.

Also, confusion appears due to the fact that the threads are unevenly tensioned: the upper one is regulated with correcting plates, and the distance between them is determined using the switch that is set to device case. As for the bottom, it is regulated by the bobbins of the bobbin case. In order to adjust the tension, you will need to take a screwdriver, remove the foot and needle plate, and then use the tool to turn the bobbin case screw to increase or decrease the thread tension.

If the lower thread does not hold the upper, and during operation of the machine, it climbs up, then the stitches can look messy or be completely confused. In this case, an increase in the lower tension by shifting the plate is required. This is done by tightening the bobbin case screw. After tightening the screw, you need to check the operation of the machine. If everything is fine, you can continue to sew further.

Threads can be confusing due to improperly located bobbins. To adjust everything, you need to use the instructions for the device. During the repair, the shuttle click characteristic of the typewriter will be heard.

If the tension is normal, but the sewing machine is not functioning properly, it may be in the device itself. It may be malfunctioning. Then, to adjust its work, you need to contact the master who knows how to repair sewing machines. Or replace the device with a new one. If we are talking about a small defect on the hook, then you need to remove the needle plate and visually evaluate what the thread comes across. To do this, turn the wheel of the lift lever, gently pull out the shuttle and look at it. If there are any burrs, they must be removed with a scalpel or other sharp object. After removing the defect, return everything back and check the operation of the device.
