The thread take-up lever is a part used to help the thread pass through various parts of the sewing machine. It is usually a slender metal rod that can be used to pass through various sewing machine channels such as thread guides, thread reels, thread tensioners, etc.
Thread Take-Up Spring (8)
During the operation of the sewing machine, the thread passes through different tension control points, such as the upper thread wheel, the lower thread wheel, the thread clamp, etc., and the thread tension needs to be adjusted by the thread take-up spring to ensure the stability and quality of the sewing effect.
Thread Gripper (9)
The thread gripper of a sewing machine refers to a device for holding and guiding the thread, usually used on a sewing machine. Its main function is to ensure that the thread maintains the correct tension and position during sewing so that a smooth and neat sewing result can be obtained.
Panel line hook （10）
Used to guide the end of the thread through the correct path. When using a sewing machine, the thread ends pass through a series of lines and guides to ensure the thread passes through and the fabric is sewn properly.
Needle Bar Bushing (11)
The needle bar bushing ensures smooth and precise movement of the needle bar, which is crucial for accurate stitching. Over time, with use and wear, the needle bar bushing might need to be lubricated or replaced if it becomes damaged or worn out.
Presser foot (12)
It applies pressure to the fabric, helping to feed it evenly through the machine and preventing it from shifting or bunching up during stitching.
Throat plate (13)
The throat plate, also known as the needle plate, is a crucial component of a sewing machine located beneath the needle and presser foot.
Types of auto sewing machine parts
Tension Regulator (1)
A tension regulator is a device used to adjust the tension of the upper thread (also called upper thread) during sewing. The upper thread tension regulator of an electric sewing machine is located on the upper thread path of the sewing machine, and it can be adjusted by a knob, paddle, or other type of adjustment device. When adjusting the tension, you can fine-tune the tension to get the best sewing results based on the type of fabric you are sewing, the type of thread, and other factors
Bobbin Winder Tension Disk (2)
The bobbin winder tension disk is an important component of a sewing machine that helps control the tension of the thread while winding the bobbin. The bobbin winder is the mechanism on a sewing machine that winds thread onto a bobbin, which is a small spool that holds the lower thread used in the sewing process.
Take-Up Lever (3)
A sewing machine take-up lever is a device that is used to guide and pass the thread through the thread, which is usually used to guide the upper thread (top thread) from the path of the thread to the needle eye of the sewing machine. The take-up lever is a very useful tool during sewing preparation to help guide the upper thread to exactly the right place to start sewing.
Speed Control (4)
The speed control button is the equivalent of a foot pedal on a traditional sewing machine and is used to control the speed of the machine. You can adjust the speed by moving the slider or turning the dial. This method provides precise speed adjustment.
Stop-key needle (5)
When the needle is inside the fabric, e.g. when turning corners or sewing complex stitches, and you need to stop sewing temporarily, simply press this button.
Backstitch button (6)
The backstitch button on a sewing machine is a feature that allows you to reinforce the beginning and end of a seam by sewing a few stitches in reverse. This helps prevent the thread from unraveling and secures the seam. When you use the backstitch button, the sewing machine will automatically sew a few stitches in reverse before continuing forward, creating a secure locking stitch.
Start-Stop button (7)
This button controls the start and stop of the machine.
Shank (8)
The shank is designed to be held by the sewing machine or other sewing tool, allowing the needle to be properly inserted and controlled during the sewing process.
In sewing machines, the shank of the needle fits into a holder or clamp, which is then secured in the machine.
Automatic Needle Threader (9)
An automatic needle threader is a handy feature on sewing machines that is designed to help sewers pass the thread through the eye of the sewing machine needle more easily, eliminating the cumbersome process of threading by hand. Operate the lever on the quick threader, this will guide the thread through the eye of the needle. Some minor adjustments and guidance may be required. Once the thread has passed through the eye of the needle, you can gently pull the thread out, ensuring that the thread is firmly threaded through the eye of the needle.
Presser Foot (10)
The presser foot is an essential component of a sewing machine. It is a small, flat piece that sits below the sewing machine’s needle and holds the fabric in place as it is being stitched. The presser foot’s main function is to apply pressure to the fabric, ensuring that it stays flat and smooth as it moves through the machine while you sew.
Machine Accessory Box (11)
A sewing machine accessory box is a box that contains a variety of different sewing accessories that usually come with or are included in the purchase of a sewing machine. These accessories can help you achieve different tasks and results in different sewing projects.
Bobbin Winder (12)
The bobbin winder is a component of a sewing machine that is used to wind thread onto a bobbin. The bobbin is a small spool-like object that holds the lower thread, which, when combined with the upper thread from the sewing machine’s needle, creates stitches. The bobbin winder ensures that the bobbin is evenly and tightly wound with thread so that it can be used effectively during the sewing process.
Menu Screen (13)
Displays the current sewing stitch condition.
