Abstract
A dust removing mechanism is applied to each unit of an open-end spinning machine. In each spinning unit provided with an opening roller and a spinning rotor for creating a yarn from fibers supplied from the opening roller, a casing partly surrounds the opening roller and a dust removing opening is formed in the casing. In such mechanism, a dust removing zone is formed so that it communicates with the dust removing opening and the dust removing zone is divided into a dust separating zone and a dust discharging zone. An air-takein opening is provided so as to create an auxiliary air stream, by which the separation of dust from the useful fibers can be effectively carried out.
