Tension of unwinding thread

The investigation of the change of the tension of the unwinding thread from the cheese as a function of numerous variables such as friction, form and size of the cheese, irregularity of the thread, form and size of the balloon etc. was carried out. On the assumption that the geometrical parameters of the bobbin are unchangeable as well as the thread characteristics and the friction coefficient, the thread tension differs proportionally to the square of the unwinding speed and the mass per length unity (equation 8) [1]. Comments were made on experimental results according to which the dependence between the size of the cheese and the tension of the unwinding thread is achieved.
