The stepping-motor-driven warp let-off unit is applied to 1515-PJR flexible rapier loom. The warp tension is measured by using IBM-PC and CRAS software package. A new measuring index of warp tension for comparing the performance of warp let-off motion is given. The statistical analysis on the warp tension in the weaving process from full warp beam to empty is conducted. Also, the spectrum of the dynamic warp tension is analyzed, and the influences of the warp let-off motion' timing on warp tension are discussed.
