Abstract: A weaving rotor of a series shed weaving machine provides a cover which forms a ring channel with the weaving rotor from a laying-in station up to the cloth edge in the direction of rotation. The ring channel is closed off by further covers, in the direction of rotation and at the side face where the weft arrives.
