Abstract :The design of a vibration beat-up mechanism with a flexible reed and magnetoelectric vibration exciter is presented. A simulation  model consisting of a thickening zone, working elements and electrically excited vibrations is elaborated. The results of the simulations  of the vibration thickening of fabric are presented. The impact of the reed vibration in relation to the decrease in the dynamic loads of  the warp or the increase in the produced fabric thickening of the weft is analysed. It was found that frequency improves the thickening  condition. However, there is a threshold frequency beyond which the thickening condition cannot be further improved.
