Sewing Machine Maintenance Checklist and Technical Adjustments

Cloth is a basic need of human beings. Can you imagine that a man cannot live without wearing a dress or cloth, a sewing machine is used to stitch two or more ply of fabric in order to make a cloth. A sewing machine uses to make cloth by sewing fabrics part together. Modern sewing machines are computerized control panel systems. This article is about Industrial sewing machine Parts Repair, Maintenance, Servicing, Troubleshooting; Problems and solutions/ remedies, and a brief discussion on the history of a sewing machine. Here I present Sewing Machine Maintenance Checklist and Technical Adjustments.

History of sewing machine

Sewing machines have a long history from their invention to the development stage, its modification to the computer-controlled modern electrical sewing machine and sewing machines have reached automation. Sewing companies are still giving their best effort to add automation by reducing human help. British Inventor Thomas Saint first designed a sewing machine in 1791 to be used on leather and canvas. Sewing machine development started in 1807, the first sewing machine was presented by an Austrian tailor, Josef Madersperger in 1817.

I am not going to write complete sewing machine history; this article is not about sewing machine history too.

Types of sewing machines
