This study focuses on the analysis of the existing design solution of shedding mechanism. It is characterised by a heald attachment into the heald shaft with a necessary design allowance. The preparation of a mathematical model for the new concept of the heald attaching to the heald shaft frame is explained in this study. A damping element for dissipating the energy created during the heald impact on the carrying wire of the heald shaft is currently used for the high-speed weaving loom. This system makes use of a damping element, fitted in the profile of the rod at an optimum distance from heald eye. This element provides for reduction of the heald velocity before its drop upon the supporting wire because the opposite section of the heald is pressed into the rubber element. The calculated results of the new concept of the heald attaching to the heald shaft frame are compared with the existing solution without application of the damping element.
