“…Other models of friction stress are also known [13,11]. Research conducted in [1,2,26], has established that for roll mechanisms the most appropriate model is the one developed in [29]; according to this model, there is a relationship between contact stresses of the form:…”

Calculation formulas for determining the energy-power parameters of roll mechanisms, such as the forces created by the roll gripping devices, the torque, and the power required to rotate the rolls were derived in the study. It was revealed that the radii of the rolls and the thickness of the processed material have the greatest influence on the energy-power parameters. Reducing the roll radius and material thickness makes it possible to reduce the gripping force related to a decrease in the length of the contact zone. As the radius of the roll decreases, the torque decreases as well due to the decrease in the radius of action of the resulting friction force.

“…According to [28][29][30][31][32] on the line of contact AE , there are sections of slip lagging areas AB , no-slip areas BD and advance slip areas DE . In this case, part of the no-slip area (segment BC ) refers to the compression zone, and another part (segment CD ) refers to recovery, therefore, the deformation properties of the contacting bodies differ.…”

The results of solving the main problems of contact interaction in squeezing machines are presented, when the deformation of the contacting bodies is given by the Kelvin Voigt models. Analytical expressions are found that describe the shape of the contact line of the rolls, as well as the patterns of distribution of normal and tangential forces. It has been established that one of the main factors determining the roll contact lines is the ratio of the strain rates of the material being processed and the roll coating. It is revealed that the point where the shear stresses change their signs is located in the sticking area.

The process of deriving the equation of the perturbed motion of a roll pair during the processing of leather material is discussed in the article, taking into account the influence of dynamic factors. It is shown that one of the reasons for the unstable stress state on the contact surfaces in the roller mechanism are dynamic factors arising from inaccuracies in the manufacture of its individual parts, assembly defects, and the occurrence of an oscillatory process in the roller mechanism, as well as due to the non-uniform thickness of the processed material at its gripping during starting and stopping the machine. Methods for determining optimal controls are shown; they provide asymptotic stability of the unperturbed motion of a roll pair and the torque applied to the upper roll as a function of generalized coordinates.It is shown that the width of the contact strip of the clamp, which depends on the radii of the rolls and the hardness of the coatings, has a significant effect on the efficiency of the rolls. The larger the shaft radius, the lower the actual pressure per unit contact area. It is shown that the squeezing efficiency increases with the improvement of the conditions for the removal of the squeezable liquid from the rolls (with their horizontal arrangement), with an increase in its temperature and a decrease in viscosity. Efficiency decreases with increasing material speed and thickness. It is shown that the width of the contact strip of the clamp, which depends on the radii of the shafts and the stiffness of the coatings, has a significant impact on the efficiency of the shafts. The larger the shaft radius, the lower the actual pressure per unit contact area
