Structure of the cloth back sewing machine

A cloth back sewing machine is a mechanical device used to sew cloth, usually consisting of many parts. Let me briefly introduce its structure.

1.Frame and Base: The frame and base of a cloth back sewing machine are usually made of sturdy metal materials to support the structure of the entire machine.

2.Motor: Cloth back sewing machines are usually equipped with motors to drive the sewing machine and provide power.

3.Belt and Drive System: The motor transmits power to other parts of the sewing machine through the belt and drive system to make it operate properly.

4.Sewing needle: The sewing machine is equipped with a sewing needle, which is used to pass through the fabric and form the seam.

5.Lower rocker arm: The lower rocker arm is an important component that helps control the movement of the sewing machine and makes the sewing process smoother.

6.Sewing Board: The sewing board is a flat surface on a cloth-back sewing machine that supports the fabric and ensures that the sewing lines are straight.

7.Fabric tensioner: A fabric tensioner is used to help the fabric stay flat during sewing to avoid wrinkles or pulling.

8.Thread Wheel and Thread Bar: The thread wheel and thread bar help guide the sewing thread, ensuring it passes smoothly through the sewing needle and forms an even seam.

9.Foot pedal: The foot pedal is usually used to control the operation of the cloth back sewing machine. The operator controls the speed and stop of the sewing machine by stepping on the pedal.

These are some of the basic construction parts of a cloth back sewing machine that work together to enable the sewing machine to do the job of sewing fabric smoothly.
