Surveillance technology for fleece fabrication plants

摘要

The invention relates to a monitoring method and a monitoring device for a production process of a preferably uncoated and unconsolidated nonwoven precursor (3), wherein properties of the nonwoven precursor (3), in particular the moisture, the electrical charge, the weight distribution, the fiber orientation, the fiber mixing ratio and / or the fiber opening degree a still unprocessed batt, with a detection device (41) with one or more sensors (410) for contactless measurements on a batt, in particular, infrared sensors, detected in a detection area (5) and the detection results are processed in a data processing unit (42) ,
