The Singer S0105 is a basic home sewing machine suitable for beginners and daily sewing needs. Here is a detailed introduction to its working principle and specifications:

Working principle

The working principle of the Singer S0105 sewing machine is based on the traditional lockstitch technology, which mainly includes the following steps:

Upper thread and lower thread

The upper thread is inserted into the fabric through the needle eye, and the lower thread is located in the bobbin. When the needle passes through the fabric, the upper thread and the lower thread are intertwined in the middle of the fabric to form a lockstitch.

Needle bar movement

The motor drives the needle bar up and down to drive the needle through the fabric. The movement speed and stroke of the needle bar can be adjusted by the foot pedal or speed control button.

Feed dog movement

The feed dog moves forward when the needle bar rises, pushing the fabric forward to ensure the uniformity and continuity of the sewing stitch.

Thread tension control

Ensure the firmness and beauty of the stitch by adjusting the tension of the upper thread and the lower thread. The tension of the upper thread is usually controlled by the tension adjustment dial, and the tension of the lower thread is adjusted by the bobbin.

Automatic backstitch

The machine can automatically backstitch by using the backstitch button or lever to reinforce the start and end of the stitching.
