ABSTRACT
In a rotor spinning machine, the basic elements are the feed, opening mechanism, rotor, delivery roller, winding drum, ventilation fan, and control system. The opening mechanism consists mainly of an opening cylinder and combing roll. The power of the opening mechanism can be divided into the technological toothed drafting of the fed sliver and the mechanical power of the combing roller. The technological opening power of the fed sliver to the feeding mechanism is determined by different formulae depending on the type of opened material such as noils of a cotton comber, virgin cotton, staple cotton, or artificial fibers. The twisting mechanism includes the rotor, the doffing tube, and the take-up roller. The power of the mechanism without material gives the no-load power the material power; the no-load power gives the full-load power for the twisting mechanism. The rotor spinning machine has a ventilation fan for cooling and air suction in the spinning box.
