A computer analysis of the motion of the spatial links of lever mechanisms has been carried out. This analysis has been presented as an example of some selected mechanisms of one version of basic design solutions for the overlock sewing machine, i.e. a needle arm driving mechanism, a gripper mechanism and a transport mechanism. On the basis of the equations of motion based on the mating of the elementary links of these mechanisms, a kinematic analysis of the motion of these elements has been conducted. The calculation results obtained in the form of discrete functions have been replaced by continuous functions, by the application of the Lagrange polynomial. The parameters of the motion of selected elements as determined are derivatives of these functions.
