- a "weaving weave” is referred to as a weave which has a low energy requirement and / or causes a low mechanical load
- a "favorable weave” is, for example, a shed formation with movement of only a few healds and / or with movement of symmetrically distributed healds. so that only a small mechanical load occurs.
- unfavorable weave is understood to mean a shed formation under high mechanical load, which, for example, also has a high energy requirement for driving the heald frames Movement only a heald, multiple healds or all heddles for reasons of stress and / or energetic aspects be favorable.
- a start of the weaving device for a weft thread to be inserted for example, also depends on a shedding during the last weft thread inserted before an interruption.
- starting the weaving device a process by which the weaving machine and the shed forming machine are started for normal operation is referred to as "starting the weaving device.”
- the second drive motor can first be started in a slow motion, wherein warp threads are fed through the shed forming machine, for example a dobby
- This movement of the warp yarns prior to starting the shed forming machine is referred to as pre-shedding, and only after the warp yarns are in the desired position, the jigging device is brought into a desired position for weft insertion, ie, a desired shed
- the shed forming machine has coupling means or the like, and after the tray forming means and / or the warp threads have been brought into a desired position, it is possible to feed the shed forming means decouple, so that the movement of the shed forming machine is not transferred to the shed forming means.
