Using the above data on the manufacture of grates and taking into consideration the bending vibrations of the saw cylinders and displacement of the grates under dynamic load. Taking into account the primary factors of sectional and individual grates ribs also in order to prevent cross-displacement of grates ribs. We modeled and introduced a new type of grates ribs for a single- chamber and two-cylinder gin, which is comprised of the top and bottom, grates ribs aligned with three brackets and tightening laths with a new type of fastening respectively. In the article, consider the simulated static load experimental model of a new grate ribs lattice, which allows eliminating lateral. Displacement of ribs at dynamic loading.

For the accuracy of the results, the study was carried out for three years. The average of each factory gins was chosen. Comparison of fiber properties processed in different cotton processing plants, with different models of fiber separators. Each sample of fiber grade 1 Namangan 77 raw cotton was obtained as a result of ginning with such factory gins 4DP-130.5 DP-130, 3HDD and Lummus gins in Namangan region. The Fiber properties of all samples were measured with the Advanced HVI Fiber Information System, to determine the yield of short fibers. The main purpose of the study is to determine which model of sawing gin to produce more short fibers. For next modernization working parts of other model gin for increasing quality of fiber.
