Definitions
- the invention relates to a method for profiling a multilayer fleece and a
- Removal belt of the nonwoven layer takes place in a defined area and with improved and in particular more controllable influencing options.
- the card can run constantly and produce a pile with constant speed and constant thickness or density, which is favorable for the pile quality. In addition, very high working speeds of Reach 100 m / min and more.
- the pile fed directly or indirectly to the stretching device is only influenced in the stretching device and is preferably stretched in the process. This stretching and the associated thinning of the pile can be precisely controlled and influence the pile in a gentle manner.
- the thickness or density of the pile can be influenced within wide limits by means of a suitable design of the stretching device, so that there are very far-reaching control options for the thickness or density of the fleece running out from the nonwoven layer.
- the drafting device has the advantage that a precise definition of the drafting length can be created by at least two spaced-apart clamping points, within which the pile supplied is influenced and, in particular, stretched in the desired manner to form drafting. Warpage formation can be controlled better and more precisely by the defined warpage length. The pile delay can thus be controlled more precisely according to position and size in the pile. In this way, the different requirements of different pile types and pile thicknesses can also be taken into account.
- the size of the drafting length and in particular the stretching length can also be influenced and changed here by means of movable clamping points.
- Elastic piles which generally also have a larger pile thickness, are preferably treated with a short drafting or stretching length. This results in a plastic deformation of the pile, which is not canceled again after leaving the clamping points and the drafting device, but instead. remains in the pile at the desired location and with the desired strength.
- the stretching device consists of several roller arrangements, in particular pairs of stretching rollers, or several
- the claimed profile forming device has the advantage that it can be used with existing fiber treatment systems without any problems together with a new fleece layer or an existing fleece layer. Neither the card nor the needle machine need to be adjusted or changed. These machines can be used as
- FIG. 2 a top view of the profile forming device and the nonwoven layer

- FIG. 8 a further variant of the drafting device with subdivided conveyor sections
- Fiber treatment plant or fleece manufacturing device (101) shown which from a pile generator (2,103), e.g. a card or card, a downstream one
- the fleece layer (3, 102) is associated with a profile-forming device (1) by integration or retrofitting, which consists at least of a drafting or stretching device (5, 104) and possibly also a compensating device (6).
- the invention relates to the profiling method and the profile forming device (1). In addition, however, it also records the fleece layer (3, 102) equipped with a profile-forming device (1) and the entire fiber treatment system or fleece production device (101).
- the pile removal device (117).
- a so-called hacker (119) is available for the pile acceptance.
- one or more take-off rollers (118) are provided for the pile removal instead of the chopper.
- the profiling device (1) is provided for profiling the fleece (9, 108) formed in the fleece layer (3, 102). It includes a drafting or stretching device (5,104) for the pile (8,107), which is arranged between the fleece layer (3,102) and the pile generator (2,103).
- the profile forming device (1) can also have a compensating device (6) for the fleece (9), which is arranged between the fleece layer (3, 102) and the consolidation device (4).
- the stretching device (5, 104) serves to change the thickness or density of the pile (8, 107), which is fed by the pile generator (2, 103), preferably with a constant thickness and constant speed, via a pile feed (10).
- the stretching device (5,104) preferably thins the pile (8,107). With the appropriate design, it can also compress and compress or thicken it if necessary.
- the profile forming device (1) has a control (7) to which the fleece layer (3, 102) is also connected.
- the stretching device (5, 104) and the fleece layer (3, 102) are controlled jointly, the profile formation of the fleece (9), which is explained in more detail below, preferably being controlled via the pile path.
- the stretching device (5) has a conveyor section with a plurality arranged one behind the other in the pile running direction (23)
- Roller arrangements (11, 12, 13) with controllable drives M5, M4 and M3. There are three roller arrangements in the embodiment shown. But it can also be more or less, e.g. shown below in Figures 6 and 7.
- the roller assemblies (11, 12, 13) form three clamping points and serve to thin and stretch the pile (8). They each consist of opposing pairs of rollers that clamp the pile (8) between them and convey them at an adjustable speed.
- the drives M5, M4 and M3 preferably drive both rollers of the roller pairs (11, 12, 13). Alternatively, you can only use one roller at a time, e.g. drive the lower roller of the roller pairings (11, 12, 13), the associated upper rollers each being designed as freely rotatable, rotating clamping rollers.
- the rollers can be designed as smooth-walled rollers. However, they can also have a roughened surface or a surface with stretching needles.
- One or more guide rollers (14) with their own drives M1, M2, which also act on the pile (14), can be arranged in front of and / or behind the roller arrangements (11, 12, 13).
- the input-side guide roller (14) is arranged above the pile feed (10) and in particular above the rear nip roller Pile feed (10).
- This guide roller (14) and its drive M2 are coupled to the speed of the pile feed (10) or the delivery speed of the pile generator (2).
- the pile (8) is clamped and conveyed between this guide roller (14) and the pile feeder (10).
- the stretching device (5) can be switched back and forth between a normal throughput stage and one or more stretching stages.
- the pass stage there is no stretching of the pile (8) so that the pile (8) retains its thickness and density determined by the pile generator (2).
- the roller arrangements (11, 12, 13), the guide rollers (14) and also the infeed belt (15) of the nonwoven layer (3) have a preferably constant one which is adapted to the pile feed speed of the pile generator (2)
- the rollers, belts and other conveying devices for the pile (8) arranged one behind the other in the pile running direction (23) can have a gradually increasing speed level in order to keep the pile (8) under a slight pull at all times, but without significantly stretching it .
- the other drives M of the nonwoven layer (3) are then set to the normal laying function via the control (7), so that a multi-layer nonwoven (9) is also present with the pile (8) deposited on the discharge belt (17) with a constant thickness constant thickness or density is formed.
- the pile (8) is thinned and stretched in the stretching device (5).
- the drives M5, M4 and M3 of the roller arrangements (11, 12, 13) in the pile running direction (23) are set to gradually increasing speeds.
- the fleece layer (3) is coupled in particular with its infeed belt (15) and on the other pile-leading drives M via the control (7) to the drive M3 of the last roller arrangement (13).
- the output-side guide roller (14) is also coupled to its drive M1.
- the infeed belt (15) and the guide roller (14) thus run just as quickly or only slightly faster than the last roller arrangement (13) of the stretching device (5) in the interest of a constant slight tensile load.
- Roller drives Ml, M3, M4, M5 and the pile-leading drives M of the fleece layer (3) increased, a predetermined acceleration ramp being followed.
- the individual roller speeds are gradually increased.
- the roller drives Ml and M3 run faster than the roller drive M4 and this in turn faster than the roller drive M5.
- the roller drive M2 and the speed of the pile feed (10) remain constant. Through these changes in speed, the pile (8) is stretched and thinned, which is in the
- Diagram shown shows a reduction in the pile thickness d.
- the stretching step remains constant for a distance s specified by the profile formation program and is then reduced again, the increased roller speeds being reduced back to the level of the throughput step. Accordingly, the pile thickness d increases again to the original level.
- the changes in speed and pile thickness shown in the diagram of FIG. 4 can in turn be varied in steps or continuously upwards or downwards in order to produce changes in the pile thickness d of different sizes.
- the stress levels can also be present over a longer or shorter distance s.
- the fleece layer (3) deposits the pile thickness changes at the predetermined positions of the laying width, forming the multi-layer fleece (9).
- the fleece layer (3) deposits the pile thickness changes at the predetermined positions of the laying width, forming the multi-layer fleece (9).
- the pile thicknesses are preferably reduced, especially in the edge areas of the fleece (9), which preferably occurs with each pile layer deposited on the discharge belt (17) when the laying carriage (16) moves forwards and backwards on both fleece edges.
- profile changes can be made in the fleece area in between.
- the formation of a nonwoven profile can serve different purposes. On the one hand, it can be used to react to peculiarities of the consolidation device (4), in particular a needle machine. Needle machines usually have the peculiarity that due to the necessary warping, the fleece (9) jumps in over the width and this width shrinkage leads to thickening in the edge area, as a result of which the end product emerging from the needle machine (4) has an uneven thickness or density over the laying width Has. This is counteracted by the formation of the aforementioned fleece profile. In addition to these marginal effects, other inhomogeneities of the needle machine (4) or another consolidation device generated within the laying width can also be taken into account. Alternatively, through the
- the nonwoven end product coming from the consolidation device (4) is given a deliberately different thickness instead of a uniform thickness if this end product is to have a certain cross-sectional profile for further processing.
- the compensation device (6) in the embodiment shown consists of an endless storage tape (18) with a variable sag of the upper run (19) and two separately adjustable drives M6 and M7 for one roll (20, 21) at the rear and front ends of the ⁇ MM P> P C ⁇ ⁇ o C ⁇ c ⁇ ⁇
