The subject of research is the process of shedding the looms type ATPR and STB. The analysis of shedding parameters for different types of shuttleless looms is conducted. The aim is to ensure uniformity of the warp yarn tension across the width of the machine within each branch of the shed. The methodology for calculation the harnesses movement for the same tension on the warp yarns within each branch of the throat with a symmetric and asymmetric shedding is introduced.The results of calculations of the harnesses movement for looms ATPR and STB with eight and fourteen heald heald pump are shown.

The proposed methodology allows to determine the amount of up-down harness movement from the average level, providing by shedding the same warp yarns tension of different harnesses within each branch of the shed. At the same time, in the process of fabric production decreases yarn breakage from deformation by shedding and the conditions of fabric formation are imroved.
