This task is usually left to human experience and skill. Japanese Patent Application Laid-Open No. Sho 59-125951 discloses an example of a weaving condition setting means which can be replaced by a manual operation. The flow rate is automatically set. (Problems to be Solved by the Invention) However, there is a correlation between the individual items of the weaving conditions, and therefore, in setting the conditions of the individual items of the weaving conditions, the overall correlation is considered. It must be set while doing. Therefore, as disclosed in Japanese Patent Application Laid-Open No. Sho 59-125941, the weaving condition setting means for automatically setting only a single weaving condition, ie, the injection flow rate at the weft insertion main nozzle, reflects the weaving reflecting the correlation. It is impossible to set the conditions, and as a result, in order to set the optimum weaving conditions for the woven fabric conditions, we have to rely on workers with long experience and skill, but still avoid long trial and error. I can't. Configuration of the invention (means for solving the problem) Therefore, in the present invention, a weft insertion device, a warp shedding device, and a control device for one loom are provided for each in-process woven fabric condition such as yarn type, weaving width, weaving density, and texture.
