- JP 03193921A shows a similar fleece system.
- she consists of a card, a first fleece layer, one downstream second card, another fleece layer and a needle machine.
- About measuring devices is on different places the thickness or the sag of the Flors measured.
- the measuring devices Laying width of the fleece coming from the first fleece layer measured to ensure the correct closing of the layers at second fleece layer to ensure laid fleece.
- the carding machine and the needle machine are the results of the measurements controlled to the desired quality of the final product to reach.
- Through the various measuring devices in the fleece system is to ensure that the Process and the fleece system run stable and constant and that a controlled relationship between the thickness or Density of the end product and the setting of the card or Needle machine exists.
- a measuring device for determining the density of the nonwoven is arranged at a suitable location behind the outlet of the nonwoven layer.
- the density values determined are used to set the profile formation device, so that the desired profile formation can be specifically set and monitored or regulated.
- the measuring device is preferably arranged behind the solidification device. In this way, it detects any density errors in the end product, which can be caused anywhere in a complete fleece system and can be compensated for by adjusting the profile formation in the fleece layer area, regardless of where it originates.
- the fleece layer and the profile forming device can be in be formed in any suitable manner.
- the profile formation by Generation of speed difference between belt and Carriage speed at the pile outlet of the laying carriage generated. This version has advantages in the targeted Control of profile creation.
- the measuring device can be used in any suitable manner be trained. For continuous operation and an online regulation is recommended optical or radiometric measuring equipment.

- This consists of at least one fleece layer (4) a measuring device (13) for direct or indirect Determination of the density of the leaking fleece (10).
- a pile generator (2) e.g. a card, upstream his.
- the pile generator (2) can also be a device for Preparation of the fibers and other suitable components exhibit.
- the pile generator (2) creates a single layer Pile (3) of any suitable fibers, e.g. synthetic fibers or natural fibers, and leads them over suitable Funding the inlet or pile inlet (15) of the Fleece layer (4).
- the fleece layer (4) folds the supplied single-ply pile (3) to form a transversely running, multi-layer fleece (10), which is placed on a discharge belt (11).
- the pile layers are zigzagged on the discharge belt (11) stored.
- the fleece (10) then becomes one suitable solidification device (12), e.g. one Needle machine or a thermofusion device, supplied in the fleece (10) in a suitable manner is solidified and compacted.
- the measuring device (13) is preferably on the outlet side behind the Solidification device (12) arranged. Alternatively or in addition, a measuring device (13) can also be used between the fleece layer (4) and the consolidation device (12) be arranged.
- the fleece system (1) cannot beyond that included system components, e.g. a Stretching device, another pile generator etc., the for example between the fleece layer (4) and the Solidification device (12) can be arranged.
- Behind the consolidation device (12) or the measuring device (13) can be a cutting device, a winding device and other suitable Plant components can be arranged.
- As a variation of the shown embodiment can also several Fleece layer (4) can be arranged one behind the other.
- the fleece layer (4) preferably has an integrated one Profile forming device (20) with which the density of the deposited fleece (10) influenced and over the Laying width can be changed in a targeted manner.
- the Profile forming device (20) can also Flor producers must be assigned. Basically, the Profile forming device (20) in any suitable Be trained and arranged. For example they correspond to EP 0 315 930, EP 0 371 948, the WO 98/37264, EP 0 659 220, DE-P 43 04 988, WO 97/19209 and DE-A-38 43 180 executed and placed his.
- the density of the fleece can be measured using the measuring device (13) (10) can be determined.
- the Measuring device (13) across the entire laying or Fleece width and measures the laying width in several places. It is recommended to optimize the Measurement results, to provide a large number of measurement points, which are arranged in a row or offset from one another and are positioned with the highest possible density.
- the measuring device (13) preferably measures continuously. Alternatively, it can also be intermittent work, the density measurement during the Production operations are carried out several times.
- the measurement results are used to set the Profile forming device (20). This setting can done manually by moving the density values over the Laying width of the measuring device (13) in a suitable Manner, e.g. be visually shown on a display. at Irregularities will occur Profile formation device (20) readjusted manually.
- the measuring device (13) via a line (14) with the Profile forming device (20) in a control loop connected.
- 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 readjusted.
- the density measurement is preferably carried out behind the Solidification 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.
- 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 during consolidation (10) on the longitudinal edges and forms a lateral Entry point. 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 increased 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.
- the measuring device (13) can be used in any suitable manner be constructed constructively and as direct or indirect density measurement work.
- radiometric Measuring devices that the fleece (10) with a Spreading width essentially evenly distributed Expose radiation and that by different Register density-induced radiation changes. Different densities can, for example, lead to one different distraction behavior and one lead to different scattering of the radiation.
- the Radiation can be of any suitable type, e.g. Beta radiation, pulsating microwaves or the like.
- optical measuring devices (13) into consideration. This applies in particular to measuring systems that with the incident light or transmitted light method with e.g. a possibly pulsating infrared light source work.
- These density measurements and measuring systems can z. B. according to DD-A-260 766, DE-A-38 16 319, SU-A-1 295 340, US-A-4,865,054 or the EP-A-0 513 013.
- the fleece (10) in several places above the laying width Pressure load cells or other suitable sensors locally weigh and determine the density.
- a Density measurement can also be done through the application of pressure or Force on the fleece (10) and measurement of the reaction force by means of a resilient pressure sensor, e.g. according to EP-A-0 087 611.
- FIG 2 shows a preferred embodiment of the Fleece layer (4).
- He is a so-called fleece belt layer designed according to WO 97/19209.
