How to Thread a Sewing Machine. The Main Accents and Aspects

Correct industrial sewing equipment threading is the key aspect to correct sewing and processing of each seam, which is the key to making a truly quality product. Industrial equipment, in most cases, looks roughly the same. Due to this fact, standardized equipment must be equally well threaded. 
 
Among the most common models of sewing equipment, a tension disc is located in the upper left corner of the machine, next to the tension arm and tension wheel. The bobbins and bobbin winder are located on the right side of the machine. The handwheel is usually located on the far left, and the stitch type switch is on the bottom right side of the sewing equipment. Considering the particular type of sewing equipment, the spool pin may be on the back of the machine or on the side next to the bobbin winder.

Correct threading is required to obtain reliable and beautiful seams, with the correct processing and securing of each individual stitch. Although most sewing equipment types differ significantly in size and model, the mechanism on home and industrial equipment is completely different. At the same time, threading is a fairly simple process that takes less than 5 minutes, nevertheless, it is the key to qualitative work. So, how to thread a sewing machine, step-by-step guide follows up.
 

Step-by-step Guide to Threading a Sewing Machine

 
Right before rethreading, turn off the power completely. The threading process is pretty simple:
  • The equipment must be turned off while threading 
  • Wind the thread around the bobbin using the special threader. The rod is at the front top side of the machine; 
  • Pull the thread through the main bobbin tension disc, then smoothly move the main bobbin to the right and start active winding, simultaneously depressing the pedal; 
  •  Afterwards, the sewing machine stops. Right after stopping, move the bobbin to the left side of equipment and start the threading process; 
  • Turn off the sewing machine. Then, use the balance wheel to lift the thread guide up; 
  • Install the thread spool using the thread spool holder. In doing so, please note that the thread must be separated at the back of the machine;

  • Move the thread through the top around the lever. The thread must be on the right;
  • Place the main working thread through the lower guide.Afterwards, insert the needle from the side of the long groove. On newer models, thread the main needle from left to right; 
  • After the top thread winding is finished, proceed to the lower thread winding; 
  • Unwind 10 centimeters of thread on the bobbin and insert precisely into the bobbin case;
  • Firstly, turn the balance wheel so that the bobbin thread comes out, creating a loop at the connection with the upper thread; 
  • After you easily end the process, place both threads behind the foot, while making sure that the upper thread goes in the middle of the foot; 
  • If the thread breaks, you probably missed the thread guide. Restart the process.

The threads leading downward should be threaded directly into the needle. Specialists strongly recommend using both hands when threading — hold the thread with your left hand, turn the handwheel synchronously with the other. 

After threading, do a test sewing. If the whole process is performed correctly, then the seam will turn out smooth and without gaps. A broken thread indicates the need to re-thread. Please note that industrial models are more complicated than home sewing machines, but threading in the vast majority of cases is performed in exactly the same way. Before starting the process, the bobbin is wound on a special holder. Immediately after, the wound bobbin is set into the bobbin case and set into place in the structure by slightly moving the plate away. 

After that, the thread spool is installed on a special holder, while threading the threads through the holes in the plate, down through the raised thread guide. With the help of the tension regulator, the upper thread enters the controller, compensator and disc nose. Thread the needle from left to right, or vice versa, depending on the specifications of the sewing equipment model. The end of the thread must be placed between the plate and the foot. That's it, the process is complete — when you turn the flywheel, the lower thread should be shown from the plate.

 

 

Threading my Machine. Professional Advices

  • Right before setting up the sewing machine, thoroughly clean and lubricate it for maximum performance;
  • At the beginning of the sewing process, operate at initial speeds to check  the thread periodically;
  • Practice with swatches or trims to experience a simple straight stitch;
  • Use only the highest quality threads so that there is no lint left in the mechanism after work;
  • If the stitching is uneven, you need to precisely adjust the tension;
  • The needle needs to be changed regularly.
  • On both sides, insert the thread into the guide plate; 
  • If on your model of a sewing machine, the thread is wound directly on the bobbin, then remove the upper thread from the guide; 
  • Check the presser foot. It must always be locked in the upper position to prevent further abrasion;
  • If the bobbin slips too quickly in the bobbin case, you can put a piece of paper inside. If you follow these simple rules and tips, then there will be no problems in threading and your equipment will work like a Swiss watch.
  • The choice of thread is extremely important. When choosing a thread, you should be guided by the following rules: 
  • Don’t use poor quality thread. Due to outdated manufacturing standards, when using these threads, sewing equipment can behave completely unpredictable; 
  • The needle markings must correspond exactly to the thread markings; 
  • Cotton thread is most often used in the basting and hand sew process, so it has a certain specificity when used on industrial sewing equipment. Be sure to pay attention to this fact when threading;
  • Profile experts strongly recommend the use of innovative polyester yarns — they are extremely strong and completely resistant to abrasion over time; 
  • When using polyester yarn, be sure to pay attention to its exceptional versatility — it can be used for all types of fabrics;
  • Please note, natural fibers are excellent for natural types of fabrics.

Conclusion

After threading the upper and lower threads, you must carefully check the quality of the resulting stitch on a piece of fabric. If the sewing machine loops noticeably, then roughness will be visible from below. If the thread breaks regularly, then it is strongly recommended to seek help from specialized specialists, who in no time will replace the thread in accordance with all technical standards.
Proper maintenance of sewing equipment is a key aspect of professional work. High-quality equipment requires maximum attention to such seemingly trifles as the proper threading, equipment cleaning, etc. By following the advice of leading professionals and the instructions for refueling your sewing machinery, you will always operate the equipment that deserves the highest rating.
