Definitions
- the invention relates to a nonwoven layer with the features in the preamble of procedural and Device main claims.
- Such a fleece layer is known from EP-0 609 907 A2 known.
- the trained as a so-called band layer Fleece layer has two relatively movable Main carriage and two endless and looped all-round driven laying tapes.
- the tapes are running parallel at least in the section between the main carriages, taking up and guiding the pile between them.
- the fleece layer on the input side has a pile pick-up a so-called tape infeed of the laying tapes. That of two Side tapes come together here and form an inlet section with an opening angle of the tapes of at least 20 °.
- the inlet slot on The entrance to the inlet section is therefore very large and much wider than the pile thickness.
- the one Laying tape fed pile is in the tape infeed with a obtuse angles obliquely downwards against the horizontal redirected. Due to the large opening angle and the wide Inlet slit, the pile is open in the inlet section and is only at the bottom between the two adjacent pulleys between the laying tapes clamped and guided on both sides.
- the pile can be in the Inlet section at high speeds from the bottom Lift off the tape. This can be especially the case with sensitive Lead to faults. In this arrangement, the Feed speed limited.
- FR-2 553 102 shows another nonwoven layer.
- the two laying tapes have two parallel juxtaposed and straight belt sections that are extend vertically downwards, making the horizontal fed pile at the belt inlet a deflection of 90 ° experiences.
- such Belt infeed also only for limited Feed speeds of the pile and Working speeds of the fleece layer can be used. If the feed speeds get too high, it can to demolish in the very light and highly sensitive Fiber pile come.
- WO 91/15618 shows a further variant of the Belt infeed, in which both laying tapes over the main carriage two large deflection rollers are guided. This forms there is also another inlet funnel for one Placing tape fed pile.
- the two large deflection rollers are horizontally next to each other at about the same height arranged, whereby the pile only about at midpoint of the two rollers by the ones that come close together here Laying tapes are recorded and guided on both sides. Before and then the tapes pass through the roller shape apart again.
- These two aforementioned fleece layers are for higher feed speeds of the pile and Processing speeds of the fleece layer designed.
- the tape inlet according to the invention as in the prior art, there is an inclined downward sloping inlet section, which, in contrast to the prior art, is formed by two tape sections running close to one another.
- the belt sections form a narrow inlet slot between their adjacent deflecting rollers when they enter the belt inlet, which slot is adapted to the pile thickness.
- the two belt sections take up the fed pile and guide it on both sides and / or cover it.
- the band sections are at an obtuse angle against the Feed or infeed direction directed obliquely downwards.
- this has the advantage that the Florum diversion takes place more gently and the acting Centrifugal forces do not get too big. Thanks to the inclined position the upper band section as a cover for the pile act on the deflection and lifting off the pile Prevent centrifugal forces, wind effects etc.
- the tape inlet according to the invention ensures a special gentle and safe picking up and guiding of the pile. He allows much higher tape speeds and Pile feed speeds while maintaining a high Functional and operational security.
- the band sections are preferably straight and can run essentially parallel over a certain distance. Alternatively, one with a sharp angle is funnel-shaped narrowing inlet section possible.
- the pile can optionally be infeed-free guided or gradually pressed together or clamped become. Due to the funnel-shaped inlet section fast moving pile and the contained therein Air is gentle over a longer distance and time pushed out. Abrupt nips, quick Air currents and turbulence that damage the pile or could destroy them. It is advantageous if the inlet section essentially is going straight.
- the pile is at the top due to the sloping inlet section Gently absorbed at the end and sharper only at the lower end redirected. It is advantageous to use the lower one Deflection point to provide at least one belt loop. In a particularly advantageous embodiment There are at least two strap loops, the first Band loop in front of the deflection point and the second Band loop is arranged behind it. This will result in the critical points of the diversion Relative speeds of the laying tapes or their Band sections prevented.
- the pile can be special can be redirected safely and unencumbered.
- the pile will preferably at three or more points in the Deflection area clamped by deflection rollers.
- the tape infeed can be stationary or mobile. In the preferred embodiments it is located or on the upper main car.
- the one running between the uppercarriage and the laying carriage Outlet path can also be at an angle to Horizontal run. This allows one more Reduction of the deflection angle of the pile in the superstructure and a reduction in the centrifugal forces acting on the pile in the redirection area.
- the lower laying tape in the inlet section can be in one Run straight ahead of the inlet. Of the The pile is fed from a feed belt onto this laying belt transfer. Alternatively, this can be done in the inlet section lower laying tape also designed as a feed belt be. In this case, the lower tape can be used for formation of the inlet gap before the inlet is redirected twice be.
- the design of the lower tape as well Feed belt saves some rollers and drives and is therefore cheaper.
- a pressure roller preferably a sieve or perforated roller lie on the pile to do this serves to remove air from the pile.
- the Feed line and the inlet line in a common Level. This plane is around relative to the horizontal inclined downwards towards the superstructure. At In such an entry zone, the pile is not unnecessary deflected and can be fed straight to the superstructure become.
- Figures 1 and 3 show a fleece layer in the top view (1), which is designed as a so-called band layer. He has an upper main carriage in a housing or frame (54) (2) and a lower main carriage (3) and can over it one or more auxiliary wagons or tension wagons (32, 34) exhibit. Above the carriages (2,3,32,34) are means suitable rolls two endless laying tapes (5,6). At least the two main carriages (2, 3) are suitable Drives driven reciprocally. The two Laying tapes (5,6) can also be and variable speed drives.
- a pile generator e.g. one Card or a cardboard-produced fiber pile (7) arrives via a feed belt (25) into the fleece layer (1). He will via a feed path (26) to or on the upper main carriage (2) guided and arrives at the one described in more detail below Tape inlet (4.9) between the two laying tapes (5.6).
- the latter are at least in the area between the two Main carriage (2,3) in a loop parallel to each other and take the pile (7) between them, transport and guide him.
- This loop area is referred to as the outlet section (27). He can extend horizontally or diagonally and the main carriage (2,3) directly or via a fixed redirection (not shown) connect.
- the Outlet line (27) straight.
- the pile (7) emerges downwards and becomes on one transversely continuous take-off belt (8) to form a fleece (23) filed.
- the laying carriage (3) moves over the take-off belt (8) back and forth, causing the pile (8) in several layers one on top of the other across and zigzag to the delivery direction is filed.
- the pile (7) becomes scale-like paneled.
- the laying tapes (5,6) step on the laying carriage (3) again apart and are made in separate loops away from the outside and then to the tape inlet (9) again returned.
- the two main cars (2,3) can form a short Pass line in the same direction as in DE-A-19 27 863 or EP-A-0 517 568 or in opposite directions with stationary Belt deflection as with FR-A-2 553 102 or the WO 91/156018 move.
- To influence the pile placement on the trigger belt (8) can be by means of the auxiliary or Tensioners (32,34) internal storage are formed. It can also be worked with delay when laying the pile, around a certain thickness profile of the fleece (23) adjust.

- the two meet behind the Laying trolley (3) again separately guided laying tapes (5,6) together, then run close together and take that from outside pile (7) between them.
- the embodiment shown serves a laying tape (5) at the same time as pile feeder (25) and is made accordingly the housing (54) of the fleece layer (1) led out.
- the Flor (7) lies open on the laying tape (5) and is transported from this to the tape inlet (4).
- the inlet slot (12) has an adjustable width that adapted to the respective requirements of the pile material can be. It is preferably somewhat larger than that Pile thickness, so that the loose pile (7) initially without Squeeze or compression can be included.
- the Width can also be equal to or less than the pile thickness and if necessary already when the pile (7) lead to a clamping in the tape inlet (4).
- the band sections (10,11) run essentially parallel. This can be strictly parallel. The distance of the Alternatively, it can also be determined by the running direction (24) reduce. This will make you look at an acute angle funnel-shaped tapering inlet section (9) formed in the pile (7) is gradually pressed together and clamped is before it reaches the lower deflection (15). At In this variant it can be advantageous to extend the width of the Inlet slot (12) larger than the pile thickness adjust. But it is also possible with a small one Slot width the pile (7) immediately upon entering the Tape inlet (4) to clamp and compression along the length to increase the inlet section (9) even further. The vote the appropriate setting depends on the type of Pile material and possibly also after Pile feed speed and / or other parameters.

This allows the width of the Inlet slot (12) and possibly also the funnel-shaped narrowing of the inlet section (9) changed become.
- the laying tapes (5, 6) can be permeable to air, so that due to the increasing narrowing of the inlet section (9) the pile pressed together with the air it contains is pushed out.
- the deflecting roller (18) is preferably horizontal adjustable and can be compared to the deflection roller (15) of the laying tape (5) can be approximated or removed. This will make the second leading point for the pile (7) influenced in the lower deflection area.
- the support roller (21) is vertically adjustable and can thereby also opposite the deflecting roller (15) be approximated or removed. With the backup roller (21) becomes the pile guide on said third Leadership influenced.
- the two begin the pile (7) receiving tape sections (10,11) approximately at the same height at the entrance of the inlet slot (12).
- the overhead band section (11) also pulled a little higher be and if necessary via the deflection point on the roller (14) protrude. This is e.g. to catch a very fast running pile cheap.
- the band section (11) but can also be arranged a little lower.
- the training, number and arrangement can also be changed the belt loops (13) at the lower end of the inlet section (9). For example, only one lower strap loop (13) to be available.
