High time differences, Delays due to pre-shed formations and / or high start-up delays of the first drive motor and / or the second drive motor are to be avoided as far as possible in order to prevent long idle times of the weaving device when starting and to avoid fabric defects.
  • the shed forming machine is driven at a desired weave with high energy requirements and / or high mechanical stress for the first weft thread to be inserted for one cycle or for several cycles of the shedding machine to form a shed with a favorable weave, which requires less energy and / or has a lower mechanical load than the desired weave, wherein the first drive motor is controlled such that a first weft insertion and / or a first striking takes place only after the shed forming machine according to the weave for the first weft insertion is driven.
  • the shed forming machine such as a dobby, is rotated by the drive motor, with shed forming means such as heald shafts, for example, selected according to a desired weave pattern and moved to form a corresponding shed.
  • the shed forming machine is started independently of a desired weave to form a shed for a favorable weave, thus energy consumption during startup is low.
