A system and corresponding method are provided for controlling production in a blow room, the blow room including a controller, a supplying machine having a supplying part, and a machine to be supplied that has a filling level measurement. The supplying machine and the machine to be supplied are connected to the controller. A production area is defined for the supplying machine and includes a minimum production and a maximum production. Production of the supplying part of the supplying machine is determined based on a filling level of the filling level measurement. When production of the production area drops below the minimum production, the supplying part of the supplying machine is shut down, the shutdown taking place independently of the filling level of the machine to be supplied.

The invention relates to a computer-implemented method for optically characterizing a textile fiber structure. A plurality of pieces of information on the color at different locations of the textile fiber structure are detected by an optical sensor system. The detected color information is transmitted to a computer (107) and is entered into a color space (2) in the form of a scatter plot (31) by the computer. A frequency density distribution (4) of the scatter plot (31) is determined, and the frequency density distribution (4) is numerically specified. The invention allows a change in the material of the textile fiber structure to be ascertained and optimizes the elimination of foreign materials from the textile fiber structure.
