How to insert a thread into a sewing machine

The quality characteristics of future things and the speed of sewing depend on the thread correctly put into the sewing machine. Inaccuracies in refueling can damage the needle and cause more serious malfunctions in the machine. Mandatory action for all masters should be given special attention in the initial phase of training and acquaintance with the new mechanism. This will help in the future to change the thread quickly and accurately the first time.

How to thread a thread in a standard sewing machine

In good faith, read the manual that comes with the sewing device. Reliable manufacturers are interested in the long work of their mechanisms. Therefore, apply detailed schemes, descriptions and recommendations for refueling. If the instructions are not at hand, do not worry! We will tell you how to perform this important operation.

For regular stitching

The principle of threading for all standard machines is approximately the same.

First you need to check the coil so that it moves well and does not get stuck anywhere. The thread should go from the thread tensioner to the thread take-up and then fall into the hole of the needle.

Between these elements there are special thread guides. It can be small hooks or springs. They are designed to direct the thread in the right direction so that it clings less along the direction of travel.

Action algorithm

Consider this process in stages.

• We proceed to screwing the upper thread. It should go through the guide and into the thread tensioner between the two plates.
• Further her pull up so that a slight click is heard. This is because there is a compensation spring inside the thread tensioner.
• Then we pass the thread through the thread take-up (upper lever).
• After that, it passes through all the thread guides encountered along the route.
• For convenience, raise the needle up and insert the thread from front to back. Leave a free end about 5 cm long. It is better to place it so that it does not interfere and is located behind the device.
• Followed by insert the lower thread, having previously disconnected the flywheel. First you need to wind the threads on the bobbin, then put it in the bobbin case.

IMPORTANT! Make sure that the machine is de-energized during these steps.

• Before the bobbin is in the special device, rewind a little thread.
• The cap is placed in the shuttle, making sure that its slot intersects with the finger of the bobbin. A distinctive sound should be heard. If all of the points listed are met correctly, then the cap will be fully locked.

REFERENCE!The threads in the bobbin should rotate strictly clockwise.

Checking correct threading

To make sure everything is done correctly, you must spin flywheel. After the needle reaches the upper and then the lower position, a small loop should come out of the recess under the foot.

Next, both threads must be connected together and put back under the scapula. They should be located behind the foot, and the upper should pass between the recess of the foot.

At the end of refueling it is necessary to check the quality of the stitch. To do this, flash a small piece on the test sample. If the thread breaks, adjustment is necessary. For example, tightening the thread tensioner.

IMPORTANT!With the foot raised, the thread should easily pass and stretch unhindered through the eye of the needle.

For double needle operation

If you need a seam that imitates the stitching pattern, then you need to choose a special double needle.

In this case refueling is done as usual, but an extra coil is needed. Both threads must be inserted into the thread tensioner located on top. Follow these steps:

• We change the usual needle to a double one. She looks very unusual, and when meeting her, some difficulties may arise. But in practice, everything turns out to be much easier. Please note that the sawn side of the needle should be directed away from itself, and the rounded side should be directed to the person.
• Both threads pass through all the thread guides encountered on the way. Eventually lower thread guides should play the role of a separator.
• The left thread is threaded into the needle on the left, and the right one needs to be inserted on the right. If the thread guide in the singular, then the left thread is passed through the thread guide, and the right one is next, tucking it under the eye of the needle.

How to thread a thread in an old-style manual machine

More ancient mechanisms use their own methods, they differ significantly from the technology of refueling new cars.

Consider the principle of threading in the Rzhev machine.

• We fix the spool of thread on the device.
• Neatly thread the thread tensioner.
• Display threadusing a special spring to compensate. Outwardly, it resembles a squiggle.
• Then lower the thread down and thread it into the needle holder.

ATTENTION!Cars of obsolete models have a special fork that throws the thread onto themselves. This device is an alternative to the thread guide.

These products can be found only occasionally. These include cars Rzhev and Volga.

Possible errors in threading

Consider the most common nuances that are the causes of breakdowns and a decrease in the quality of tailoring.

• The spring responsible for adjusting the voltage does not hold the thread well. This is pretty easy to spot. When lowering the legs, the thread is inserted into the needle and directed upward. With the foot raised, the needle is released and the thread stretches well. This technique should be applied repeatedly, fixing how tight the tension is. If there is no snag during tension, the reason lies in the tensioner spring.
• The thread is pulled. This can be seen at the seam on the inside. The line winds and looks uneven, messy. In this case the tension of the bobbin thread should be adjusted.
• The lower thread is denser in volume. The upper thread serves as the main thread in each line and is responsible for the lower thread, which should be thinner. A thread should be selected taking this requirement into account. The stability of the entire device as a whole and the qualitative characteristics of the products received in the future depend on the correct choice of material.

It is worthwhile to understand that there are no trifles in working on a sewing machine, therefore a strictly fixed sequence of actions must be observed.

We hope that this article will help you understand the key points of this process.
