Abstract
A method of operating a weaving machine and a shedding machine aims, to achieve so-called soft starts and soft stops, in particular, of the shedding machine. The weaving machine is equipped with an electromotive main drive and the shedding machine is equipped with an electromotive auxiliary drive. In the method the shedding machine is started at a time point (t1) that lies before the starting time point of the weaving machine, and, upon a triggered interruption of the weaving process, a shedding machine comes to the standstill at a time point (t5) that lies after the standstill time point (t4) of the weaving machine.
Claims8
Method for operating a weaving and shedding machine, whereby the weaving machine is equipped with an electromotive main drive and the shedding machine is equipped with an electromotive auxiliary drive, wherein the electromotive main drive and the electromotive auxiliary drive is actuated in a signal transmitting manner with a control device, wherein the weaving machine and the shedding machine is brought from the standstill to a prescribed rotational speed, and wherein, upon an occurring interference, the weaving machine and the shedding machine are shifted into the standstill by braking means, characterized in:
- that the shedding machine is started within a time window Δt1 before the weaving machine,
- that the weaving machine is started after expiration of the time window Δt1 at a time point t2 lying outside of the time window Δt1,
- that the shedding machine and the weaving machine, after their starting process, are operated approximately synchronously as of a fixable time point t3,
- that the synchronous operating manner of the weaving and shedding machine is terminated upon an electrical signal detecting an operating interference, and
- that thereupon the braking process for the weaving and shedding machine is initiated in such a manner, that both machines come to the standstill at different time points.
