T 1 = T 2 e fα ;
ΔT 1 = ε (t) EhH,
Where
J is the moment of inertia of the roll with a rolling pin;
P is the weight of the roll with a rolling pin;
R is the radius of the roll;
f is the coefficient of sliding friction between the layers of material;
a - shoulder rolling friction roll on the roller;
α is the angle of contact of the roll with the roller;
ε (t) is the law of change in deformation in the winding zone;
