“…There is a large amount of experimental data on the patterns of deformation of leather, fabrics, cotton, paper and other materials pressed in roller machines, as well as rubber, wool, industrial cloth and a number of others used to cover rollers. An analysis of these data showed that the deformations of the contacting bodies of squeezing machines are described mainly by empirical dependencies n A   [20][21][22][23][24][25][26][27][28], where…”

This study deals with the issues of mathematical modeling of curves of contact of rolls of squeezing machines. The paper deals with the issues of mathematical modeling of curves of contact of rolls of squeezing machines. Equations are obtained the of curves contact of the rolls of the squeezing machine, in which the upper roll is mixed relative to the lower roll towards the movement of the processed material, the processed material is fed so that the line, which is a continuation of its front end, passes through the axis of rotation of the upper roll. It was been established that the contact curves of the rolls depend mainly on the deformation and geometric parameters of the processed material and both rolls, as well as the coefficients of friction between the contacting bodies.

“…In some articles on this issue, the back of the contact curve is represented as a straight line and in others, as a curve. In some publications, it is believed that the line of contact of an elastic wheel with deformable ground is part of a circle, and in other studies, a complex line that is not part of the circle represents [7][8][9][29][30][31].…”

The study is devoted to the analysis of the contact shape in a symmetrical roll module for the case when changes in the thickness of the material and the roller coating at each point of the contact zone occur in the vertical direction of the strip of material. A mathematical model of the shape of contact between a deformable material and elastic rollers is developed. Particular types of mathematical models of the contact shape are obtained in cases where the material being processed is absolutely elastic, elasticviscous, and plastic. It was revealed that the shape of the contact depends primarily on the geometric and deformation properties of the strip of material being processed and the roller coating, and the deformation rate.

“…Solutions to the problems of contact interaction in roller machines, where the work rolls have an elastic coating, depend on how fully it represents the laws of deformation of the contacting bodies [4,5]. An analysis of the experimental data [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] has shown that, in general, the deformation of such contacting bodies of roller machines is described either by empirical formulas of the form n A   , or by rheological models of the form…”

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.
