Improvement of Needle Bar in Textile Machine by Hitting Process
The research conducted was to study the hitting process of a needle bar used within textile machinery and how to improve its efficiency and performance. A needle bar consists of a brass bar attached with a number of small pins. The primary focus was learning technique while straightening the needle bar. In order to join pins and brass bar together, the soldering is applied. The result from the heat transfer during soldering process can cause the brass pins to bend, which is undesirable for finished product. A soldering expertise uses hitting movement technique to modify and straighten the brass bar. Even though soldering process is the only step in making the brass bar; however, its method is considered very complicated and requires refinement and specialization from the maker.
