The invention relates to a method for the controlled run-up of a weaving and shedding machine, wherein the weaving and the shedding machine are connected with a controller, wherein the weaving machine is driven by means of a main drive, wherein the shedding machine is driven by means of an electric motor auxiliary drive, wherein the weaving and the shedding machine are connected by means of a common converter intermediate circuit for the energy flow transmission, wherein the shedding machine is started at a time point t0 and is run-up until to a time point t1 to an overspeed that lies above its operating rotational speed, wherein the time point t1 lies before a time point t3, wherein the weaving machine is started at a time point t2 and wherein the start phase of the weaving machine lies in the time interval from the time point t2 to the time point t3, and wherein a power transmission (feedback) by means of the converter intermediate circuit from the shedding machine to the weaving machine is carried out in the stated start phase. The method according to the invention is characterized in that the shedding machine is run-up to a predetermined overspeed between the time points t0 and t1, and that the gradient of the rotational speed progression of the shedding machine is more negative in a later section of the start phase than in an earlier section.
