Course Overview

Principles of combing, Roving preparation & Ring spinning by Swayam will focus on three methods, such as combing, roving preparation and ring spinning, as the subject. It will look into the construction, design features and working principles of the machines. The focus would be on "know why" instead of "know how". It will clarify the role of the machine and process parameters in process efficiency. It will address the relationship between technology and the design of machines.

Through the finely formulated course format, the candidates will not only be able to attain a clear understanding of the functioning of machines and its relation with technology and design of machines but also grasp the knowledge of machine working parameters.

The course offered by Swayam provides candidates with an extraordinary opportunity to escalate their basic knowledge of machines into a professional understanding of various aspects that are responsible for the performance of a machine.
