An instrument for identifying at least one of fiber blend composition and fiber blend ratio in an input material moved by a third set of fiber movements. A second spectral radiation source directs radiation toward the input material. A second spectral sensor receives portions of the second radiation that pass through the input material. A third spectral sensor receives portions of the second radiation that reflect off of the input material. A controller processes the signals from at least one of the second spectral sensor and the third spectral sensor to determine at least one of the fiber blend composition and the fiber blend ratio in the input material. The controller also sends control signals to the second electromagnetic radiation source and the third set of fiber movements.

A monitoring process is provided for a method for producing a nonwoven product. Properties of a nonwoven pre-product (3), in particular the humidity, the electric charge, the weight distribution, the fiber orientation, the fiber mixing ratio and/or the fiber opening degree of an unprocessed fiber web, are detected by a detection unit (41) having one or more sensors (410).

A monitoring process is provided for a method for producing a nonwoven fabric (7) made of fibers (1, 2) in a nonwoven fabrication plant (15). Humidity and/or the electric charge of the fibers (1, 2) or a nonwoven pre-product (3) is detected by a detection unit (41) in a detection zone (5) and the detection results are processed in a data processing unit (42). An actuation command (45) is generated for at least one actuation unit (50) of the nonwoven fabrication plant (15). The actuation unit (50) is configured to set the humidity of the fibers (1, 2) and/or the humidity of the nonwoven pre-product (3) and/or the ambient conditions in at least one portion of the nonwoven pre-production plant (10).

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.

A method is provided for determining a functional status at a workstation of a textile machine that includes a plurality of the workstations, wherein each workstation includes at least one drive associated with a treatment device configured at the workstation to treat a fiber material. The method includes measuring a load variable of the drive and determining the functional status of the treatment device based on the measured load variable.

A method and associated device and system are provided for recording trash in a fiber preparation system having a plurality of cleaning points and a transport line that is connected to the cleaning points and is guided into a central container connected to a negative pressure source for generating transport air. The trash is suctioned from each cleaning point through the transport line with the transport air to the central container and is feed separately from each cleaning point to the central container. In the central container, the trash is separated from the transport air and transferred into a scale for weighing. With the trash located on the scale, an optical recording of the trash is made with a camera directed to an interior of the scale.

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.

An electronic device, and associated method of operation, determines a classification of a current production output of one or more parts of a spinning mill. The electronic device is configured to: determine the current production output of the spinning mill parts; determine a current configuration of the spinning mill; based on the current configuration, look up an expected production output of the spinning mill parts in a database; and determine the classification of the current production output by evaluating the current production output with respect to the expected production output for the current configuration of the spinning mill.

In one aspect, a textile machine for processing and/or transporting fiber material includes at least one processing unit configured to process and/or transport fiber material and at least one sensor unit configured to detect soiling on and/or at the at least one processing unit and/or damage to the at least one processing unit. The textile machine also includes at least one display unit configured to display the soiling on and/or the damage to the at least one processing unit.
