The article provides information on a method for determining friction forces in disctensioners of a sewing machine. This article presents calculation schemes for the implementation ofplate and spring structures, graphs of the dependence of the friction force between the needle threadand the surfaces of the plates in the plate thread tensioner, as well as graphs of the dependence ofthe productivity of the sewing machine.This friction force was calculated based on the Amonton–Cloun law. Calculation diagrams ofvariants of the needle thread plate and spring structures have been completed.A method has been developed for calculating the friction force created by the needle threadwith the surfaces of the tensioner plates for existing tensioner designs. A formula has been determinedfor calculating the friction force between the surface of the needle thread tensioner plates with therecommended conical base and adjustment springs.Graphs were constructed of the dependence of the friction force between the threads and theplates on the tension coefficients of the conical springs of the current design and the tensioner withthe recommended double-spring plates. In order to reduce the friction force, the linear componentsof the conical springs of the thread tensioner, which are mainly recommended for equal values of thecoefficients of unity, range from (2,5 ÷ 2,8) · 10ସ݊/݉ , and the nonlinear components are(0.25÷0.30) · It is advisable not to exceed (0,25 ÷ 0,30) · 10ସ݊/݉ଷ.
