The article examines the devices that affect the process of yarn production on an OE spinning machine. It has also been studied that densifiers and twist distributors depend on the properties of the yarns being formed, the diameter of the spinning rotor, and the linear density of the yarn. It was analyzed that different funnels and torque stops have a different effect on the stability of spinning and yarn quality in the process of yarn formation. To introduce a new intensifier into the spinning process, full-factor experiments were conducted to modify the machine parameters, and regression equations were constructed.
