The article is devoted to solving one of the basic hydraulic problems of the theory of roller pressing of sheet materials. Analytical dependencies are obtained that describe the distribution patterns of hydraulic pressure during roller squeezing of sheet materials. The analysis of the calculations showed that the obtained patterns of changes in hydraulic pressure are consistent with the theoretical conclusions and experimental diagrams obtained by other researchers.

The process of gripping material with two driven rollers in an asymmetric two-roll module is analyzed in the article. Analytical expressions for the minimum and maximum pushing force to grip material with two driven rollers in an asymmetric two-roll module were determined. Analytical expressions were obtained for calculating the contact angles of the free and forced grip of material with two driven rollers, which are the basic quantities that determine the boundary conditions of the contact interaction problems. A condition for forced gripping in an asymmetric two-roll module was found. From this condition, the conditions for forced gripping of the process of symmetric rolling were obtained.
