Abstract
The dependences for determination of normal tension on a contact
surface at a deposit of a rectangular and wedge-shaped strip and
during the strip rolling were carried out with the use of linear distribution of tangent tension in the zone of plastic deformation with signvariable friction forces and conditions of plasticity of Mises. Comparison of the received results was executed to the known decisions. It was shown that the use of approximate condition of plasticity, which was written down in the main tensions, led to essential reduction of the calculated values of technological loadings.
