  • the profile forming device (20) can do this a suitable freely programmable control (5) which e.g. a computer with one or more Processors, suitable interfaces and one or more Data and program storage included.
  • a target / actual value comparison of the delivered Density data carried out and depending on the result the profile forming device (20) corresponds to a required control logic. This will make the Density of the fleece (10) continuously or at least intermittently monitored and automatically when required adjusted.
  • the density measurement is preferably carried out behind the Strengthening device (12) on the compressed fleece (10) and thus on the end product. This will result in density errors recorded at any point within the Fleece system (1) can occur. Then you will regardless of the causer about the Profile formation device (20) readjusted and compensated. If the measuring device (13) is arranged Density errors can occur immediately behind the fleece layer (4) recorded in and in front of the fleece layer (4) arise. Density error in the solidification device (12) are not determined by this.
  • the solidification device (12) One of the main causes of the density errors mentioned is the solidification device (12).
  • the solidification device (12) comes from House to increase the fiber density in the edge area the fleece (10).
  • the fleece shrinks as it solidifies (10) on the longitudinal edges and forms a lateral Jump. This leads to a higher compression in the longitudinal edge areas of the fleece (10).
  • This Effect is made via the profile forming device (20) counteracted by the interior between these Margins in the formation of nonwovens by reinforced Flora deposit and an associated increased Fiber feed is increased. To compensate for this edge compressions essentially occur all types of solidification devices (12).
  • Another cause also come Tolerances and irregularities in the formation of fleece and profile formation as the cause of compaction errors in Consideration. The actual profile formation then deviates the settings. All of these causes can be caused by the Measuring device (13) in connection with the Profile forming device (20) can be compensated.
