The results of research on determining the influence of saws' sailing and their displacement in the grate gap are presented. The relevance of the research is substantiated and a theoretical analysis of the fiber tension forces arising when the saw is located off-center in the grate gap is performed, it is indicated that as a result, the fiber tension depends on the grate wear and the position of the saw. At the grate, to which the saw is closer, the wrap angle increases, so the likelihood of fiber breakage also increases. The performed experimental studies have shown that the off-center position of the saw in the grate during ginning leads to the appearance of a lateral force acting on the grate. The magnitude of the force depends on the stiffness of the saw and, with its deformation by 1 mm, was at various points from 10.8 to 12.3 N. The maximum deformation of the saw under the action of a force of 10 N was 0.92 mm, and the minimum was 0.81 mm
