Analysis of the angles of contact in a two-roll module

Abstract

Abstract The study is devoted to the analysis of the angles of contact in a two-roll module. An asymmetric two-roll module is considered, in which the rolls are inclined to the right relative to the vertical line, they have unequal diameters and elastic coatings made of materials of different stiffness and friction coefficients; the material layer is fed down inclined relative to the centerline. Analytical expressions for the angles of contact are obtained, which are the main quantities that determine the boundary conditions for the problems of contact interaction in a two-roll module. It was stated that the sum of the contact angles does not depend on the inclination of the material layer feeding to the centerline and on the inclination of the upper roll relative to the vertical line.
