ABSTRACT:
The invention relates to weft or filling thread beat-up mechanisms and can be effectively utilized in travelling wave shedding looms. The beat-up mechanism includes a series of discs mounted on a shaft, each disc having teeth of different heights radial, increasing in the weft thread beat-up direction, each tooth having the merging point of its rear or trailing edge and its outer edge situated radially higher than the merging point of its leading or front edge and this outer edge, whereby the breakage of both warp and weft threads is significantly reduced.
