ABSTRACT:
The shed of a fluidic weaving loom is not changed simultaneously for all warp threads, but rather continuously starting at the weft entrance and continuing helically, so to speak, to the exit of the warp shed. This sequential shed closure takes place with a so-called domino effect along a helical line curved in space, whereby additional time is gained for stretching the inserted weft thread and temporarily stopping the shed formation or shedding is avoided.
