We estimated the elastic characteristics of raw cotton and calculated spreading efforts. To determine the numerical values for the pressure forces at which a blade acts on the flow of raw cotton for a coefficient k of the generalized properties of a material the magnitude for raw cotton was adopted in a range of 0.25-0.3. Experiments have shown that a layer of raw cotton with a thickness from 170 to 380 mm and a width of 700 mm was loaded with the force of 30-100 N concentrated along the line. Based on our calculations it was established that 38.89 of the raw cotton cleaning time accounts for the operation of a single blade of the roller. The result of our experimental and theoretical research is the data that make it possible to organize effective operation of cleaning machines in the cotton
