Sewing Machine:
A sewing machine is a machine used to stitch fabric, paper, leather, or other materials together using thread. It is a very important machine in the garment manufacturing industry.
History of the Sewing Machine:
The invention of the sewing machine was not done by one person. Many inventors contributed over time.
- 1790 – Thomas Saint (England): He invented the first sewing machine and took a patent for it. His machine could make only chain stitches.
- 1832 – Walter Hunt (USA): He invented a machine using an eye-pointed needle and a lock stitch.
- 1845 – Elias Howe (USA): He developed a sewing machine with an eye-pointed needle and an under-thread shuttle. His machine could sew much faster than hand sewing.
- 1851 – Isaac M. Singer (USA): He improved the machine by adding a straight needle and continuous stitching, making it suitable for industrial use.
Different Parts of a Sewing Machine and Their Functions:
Although there are different types of sewing machines, the basic parts and functions are almost the same.- Bed: The bed is the flat base of the sewing machine. It supports and stabilizes the machine during sewing.
- Bobbin: The bobbin holds the lower thread.
- Bobbin Case: It holds the bobbin in place and controls the tension of the lower thread.
- Bobbin Cover: This cover protects the bobbin and bobbin case.
- Bobbin Winder Spindle: It is used to wind thread from the spool onto the bobbin.
- Needle Plate (Throat Plate): It is a metal plate with a hole that allows the needle to pass through.
- Needle: The needle carries the upper thread and stitches the fabric. It is one of the most important parts of the machine.
- Feed Dogs: Feed dogs are small metal teeth that move the fabric forward during sewing.
- Presser Foot: The presser foot holds the fabric firmly while sewing.
- Presser Foot Lever: This lever raises or lowers the presser foot.
- Thread Guides: Thread guides direct the thread from the spool to the needle.
- Thread Take-Up Lever: It pulls the thread back after each stitch, making the stitches even.
- Thread Tension Control: This control adjusts how tight or loose the stitches will be.
- Spool Pin: The spool pin holds the thread spool. It can be vertical or horizontal.
- Hand Wheel: The hand wheel is used to manually raise or lower the needle.
- Stitch Selector: It is used to choose the type of stitch, such as straight stitch, zigzag stitch, or decorative stitch.
- Stitch Length Controller: It controls the length of stitches. Usually, the range is from 0 to 4 (0 = shortest stitch, 4 = longest stitch).
- Foot Pedal: The foot pedal controls the speed of the sewing machine—starting, running, and stopping.
- Reverse Lever: This lever allows the machine to sew backward. It is mainly used to secure stitches at the beginning and end.
