Abstract (en)
[origin: WO0052239A1] The invention relates to a method and device for conducting quality control of a strip (37, 44, 50) made of textile fibers which is moved in the longitudinal direction thereof. In order to provide a device and a method which make it possible to prevent in a targeted manner the occurrence of flaws in a strip and to be able to produce a strip which has the fewest possible variations with regard to cross-section or mass, variations in the mass of the strip should be continuously detected and converted into an electrical signal. In addition, this signal should be compared with a plurality of predetermined limiting values, whereby limiting values are provided for variations occurring perpendicular to the longitudinal direction, and limiting values are provided for variations occurring in the longitudinal direction of the strip.
