III. Working Principle of Lock Stitch Cushion Sewing Machine

A. Sewing Process Overview

1. Threading the Machine

1. Before starting the sewing process, the machine needs to be threaded correctly. This involves loading the upper thread onto the spool and threading it through the various guides and tensioners. The lower thread is loaded onto the bobbin and inserted into the bobbin case.

2. Threading the machine properly is essential for smooth sewing and to ensure that the lock stitch is formed correctly.

2. Fabric Placement

1. The fabric to be sewn is placed under the presser foot and aligned with the desired seam line. The presser foot holds the fabric in place during sewing and helps to feed the fabric through the machine.

2. The user can adjust the pressure of the presser foot according to the thickness of the fabric to ensure proper stitching.

3. Sewing Operation

1. Once the fabric is in place, the sewing machine is activated. The needle moves up and down, penetrating the fabric and forming a loop with the upper thread. As the needle moves up, the bobbin thread catches the upper thread loop, creating a lock stitch.

2. The feed dog then moves the fabric forward, allowing for continuous sewing. The speed of the sewing can be adjusted depending on the user's needs.

4. Finishing Touches

1. After the sewing is complete, the user can trim any excess thread and press the seams to give the cushion a neat and professional finish. Some machines may also have automatic thread cutters for added convenience.

B. Key Components and Their Functions

1. Needle and Needle Bar

1. The needle is the main tool for creating the lock stitch. It penetrates the fabric and forms a loop with the upper thread. The needle bar holds the needle and moves it up and down during sewing.

2. Different types of needles are available for different fabric thicknesses and types. Choosing the right needle is important for achieving optimal stitching results.

2. Bobbin and Bobbin Case

1. The bobbin holds the lower thread and is inserted into the bobbin case. The bobbin case interacts with the needle to form the lock stitch by catching the upper thread loop.

2. The tension of the bobbin thread can be adjusted to ensure proper stitching. A balanced tension between the upper and lower threads is essential for a strong and durable lock stitch.

3. Presser Foot

1. The presser foot holds the fabric in place during sewing and helps to feed the fabric through the machine. Different types of presser feet are available for different sewing applications, such as straight stitching, zigzag stitching, or sewing on buttons.

2. The pressure of the presser foot can be adjusted to suit the thickness of the fabric being sewn.

4. Feed Dog

1. The feed dog moves the fabric forward during sewing. It is responsible for ensuring that the fabric is fed evenly and at the correct speed.

2. Some machines may have adjustable feed dogs, allowing for different fabric thicknesses and sewing speeds.

5. Motor and Drive System

1. The motor provides the power to drive the sewing machine. The drive system transmits the power from the motor to the various components of the machine, such as the needle bar, feed dog, and presser foot.

2. The speed of the motor can be adjusted to control the sewing speed. Some machines may also have a reverse function for added versatility.
