The article considers a winding mechanism with a friction drive of the package, designed for machines with a constant speed of product output. When adjusting winding mechanisms installed in production and when creating new designs, the task of reasonably selecting technological parameters that ensure the formation of bobbins of a given quality arises. In order to improve the quality of winding on a spinning self-twisting machine, a new device for dispersing defects in the winding structure was proposed during the research. It is shown that in order to ensure high-quality winding, such a mechanism should be equipped with a device for dissipating structural defects in the form of a rope and tape winding. The proposed original method for eliminating design defects is based on periodically increasing the diameter of the winding shaft. It is found that the main factors affecting the efficiency of the dissipating device are the amplitude and period of change in the diameter of the winding shaft. A second-order factorial experiment was conducted to identify rational operating modes of the dissipating device. As a result of the experiment, a regression model was obtained for the relationship between the generalized winding structure quality indicator and the amplitude and period of change in the winding shaft diameter, with a confidence level of 0.95. It was found that the greatest effect of dissipation of structural defects is achieved with an amplitude of change in the diameter of the winding shaft Δdb = 1 mm and a period of change T = 22.5 of the thread guide stroke. The change in winding structure due to the use of a scattering device is clearly shown. The proposed method of automated control of the density and geometric parameters of packages will significantly improve the quality of packages and, as a consequence, the products of the textile industry.
