Abstract: In accordance with the proposed method, in the course of shedding, thread length compensation after a change of a shed, and adjustment of different amounts of tension applied to tight and slack shed sides, warp threads are placed under a tension close to the looming-up tension maintained while the main shaft turns through from 250.degree. to 340.degree., and at the beat-up moment the warp threads are subjected to a maximum tension, the thread tension being increased while the main shaft turns through the remaining 20.degree. to 110.degree..
