In cold rolling of strip, geometrical, kinematical, and tribological asymmetries in the roll gap can exert an influence on roll force and torque. For its calculation the elementary theory of rolling is modified. The statics on the strip element are described in polar coordinates. The effects of non‐horizontal strip entry and of different diameters of the upper and lower work roll are investigated in detail.
