摘要：A weaving machine operates with warp thread tracks which lead from warp beams towards a shuttle race at which a fell of the cloth can be established and the weft thread or weft threads can be drawn in with a reed during ongoing weaving. Immediately before the interaction of the reed with the weft thread or weft threads, a momentary friction or increase in friction is produced between the warp threads and a member arranged in the warp thread track between the magazine and the fell of the cloth. The friction or increase in friction is produced by brake members which are activated such that a reduction is achieved in the flexibility of the warp threads at the fell of the cloth during the interaction between the reed and the weft thread or weft threads.
