Abstract: Both physical and mathematical models of lockstitch tightening are determined. The basic dynamical equation is a second-order differential correlation with respect to time; the forces applied are analysed and defined. The supplemented correlations are formulated by means of basic physical phenomena. The total angle of contact on the mobile barriers of the disc is introduced by physical analysis of the take-up mechanism. Both mechanical and thermal elongation are determined within the thread and introduced into the basic dynamical equation. The set of equations can be solved by means of any processing software (for example Mathematica) and the results obtained visualised for different parameters.
