Abstract (en)

[origin: WO2004020717A1] The aim of the invention is to arrange the start-up and stopping process with separate drives for weaving and shedding machines such that the necessary electrical currents or powers can be kept as low as possible and/or as regular as possible with a high degree of control and operational security. Said aim is achieved for the start-up phase, whereby the weaving machine is firstly operated at a crawling speed after a start time (t2), which can be set just before, at the same time, or just after the start time (t1) of the shedding machine, whilst the shedding machine is accelerated up to operating speed with an acceleration dependent only on the drive and the weaving machine is then accelerated sharply out of the crawling speed movement to operating speed after reaching a given position, speed, or torque value, or on reaching a time (t3). According to the invention, on stopping, the weaving machine is correspondingly sharply decelerated to a crawling speed operation in order to come to a standstill at a time (t11), which can be set to be just before, at the same time, or just after the stopping time (t12) of the shedding machine, whilst the shedding machine is braked more slowly relative to the sharp braking process for the weaving machine. In a preferred embodiment there is also the possibility of arranging the start of the shedding machine, either by presetting or by independent control of the drive system such that the working speed necessary for the operation is first achieved after the beat-up of the weaving machine and the stopping of the shedding machine is introduced before the stopping of the weaving machine (after beat-up).
