An analytical dependence was obtained that describes the patterns of friction stress distribution in the contact zone of roller mechanisms. The patterns of distribution of friction stresses from external forces acting on the roll supports, geometric and kinematic parameters of the roller mechanism, and strain properties of the processed material and elastic coatings of the rollers were determined. Mathematical models of friction stress of roller mechanisms were developed, considering the kinematics of the contact zone, the kinematic connection between the working rolls, and the compliance of the material being processed. It was established that the ratio of friction stress to normal stress at the points of the contact zone of the roller mechanism is not constant, but changes at each point of the contact zone.
