Definitions
- the invention relates to a nonwoven layer and a method for guiding a pile having the features in the preamble of the method and apparatus main claim.
- Such a nonwoven layer is known from EP 0 865 521 B1.
- Trained as a so-called sliver layer has two relatively movable main car and two guided in loops endless and circumferentially driven bands.
- the ribbons run parallel in an angled guide zone on the upper main car and between the main cars, picking up and guiding the pile between them.
- the guide zone has on the input side an oblique tape inlet of the laying belts on the upper main carriage.
- the laid up on two sides slide bands meet here and are merged to form a EinlaufSchlitzes.
- the pile fed on one band is deflected downwards in the band inlet.
- the two bands have two parallel side by side running and straight band sections that form the said inlet slot and record the pile between them by clamping and lead.
- the tape inlet has seven pulleys and two belt loops.
- the two pulleys at the lower end of the straight band sections are arranged obliquely one above the other and are closely adjacent to the Florklemmung.
- the outer tape is then lifted in a first belt loop and fed to another deflection roller again, which is also arranged to Florklemmung closely adjacent to the lower pulley of the inner florstoryden laying belt.
- Said outer laying belt is then deflected again in a second recurring belt loop and again in parallel position brought to the inner band.
- the pile is thereby also guided and clamped on both sides in the deflection regions of the laying belts and between closely adjacent deflection rollers.
- FR-2 553 102 shows another web laying machine with a stationary belt entry, in which the laying belts are brought together on stationary deflection rollers and guided in parallel position to the upper main carriage.
- the belt sections come apart again and are deflected vertically downwards, whereby the horizontally fed Flor undergoes a deflection by 90 ° and is guided only on one side.
- WO 91/156018 shows a further variant of the tape entry, in which both guide belts are guided on the main carriage via two large guide rollers. This also forms a further inlet funnel for on the one Ribbon fed pile.
- the two large guide rollers are arranged horizontally next to each other approximately at the same height, whereby the pile is received and guided on both sides only approximately at midpoint height of the two rollers by the here close fauxammen impartden slide bands. Before and after, the bands are separated by the roll shape.
- these two aforementioned nonwoven layers are designed for higher feed rates of the pile and processing speeds of the nonwoven layer.
- the only point or line merger of the bands and the correspondingly short guide length nevertheless results speed limiting problems.
- DE-A 24 29 106 form the two levers a horizontal inlet slot, which adjoins the coming of the card feeding conveyor.
- the bands are detached from each other, whereby the pile is deflected by 90 ° down and transported and guided only on the one underlying laying belt.
- DE-A 19 27 863 the pile is fed via a stationary upstream conveyor belt and before the tape entry in free fall to an underlying somewhat oblique
- the invention solves this problem with the features in the method and device main claim.
- the claimed nonwoven with the oblique tape inlet and the inlet section has the advantage of a better and gentler pile guide in the area of the superstructure. With the nonwoven and the Flor Introductions vide a clamping of the pile is avoided at the deflection of the tape inlet. A two-sided leadership and clamping of the pile takes place only in those band areas in which the
- the tape inlet can have a forward or a backward inlet path.
- the backward variant offers the advantage of a softer Florumlenkung at the lower deflection.
- the superstructure may have a more compact design.
- the tape entry also has the advantage that it manages with fewer pulleys. This reduces the construction costs and the size of the superstructure.

- the nonwoven layer (1) can also have one or more auxiliary carriages or tensioning carriages (31, 32).
- About the carts (2,3,31,32) are guided by means of suitable deflection rollers or guide rollers two endless belts (5,6).
- At least the two main cars (2, 3) are supported by running gears (20) with rollers (29) on preferably common running rails (28) and are reciprocated by suitable drives and move relative to one another.
- the two guide belts (5, 6) are likewise driven in rotation by means of suitable control and controllable drives.
- the one ribbon (5) is below as a feed belt and the other ribbon (6) referred to as counter-band.
- That produced by a pile producer (not shown), e.g. a carding machine or a carded, produced Faserflor (7) passes over a separate or from a section of

- the laying belts (5, 6) are guided on the uppercarriage (2) and in the following area (41) between the two main carriages (2, 3) in an angled belt loop close together and essentially parallel to one another. If necessary, take the pile (7) with light pressure between them, transport and guide it.
- This angled loop area is referred to as a guide zone (27).
- the guide zone (27) is divided into the band inlet (4) and the subsequent zone area (41) between the main carriage (2,3).
- the zone area (41) can extend horizontally or obliquely and connects the main cars (2, 3) in a straight line and directly.
- the pile (7) emerges downwards at the pile outlet (37) and is deposited on a transverse endless draw-off strip (8) to form a multilayer nonwoven (23).
- the laying carriage (3) moves back and forth over the draw-off belt (8), whereby the pile (8) in several layers one above the other transversely and in the Zigzag is deposited to the direction of delivery.
- the pile (7) is padded like scales.
- the laying belts (5, 6) separate again at the laying carriage (3) at the web exit (37) and are moved outwards in spatially separated loop sections and are conveyed via e.g. fixed frame deflection rollers (42,43) and possibly existing tensioning carriage or auxiliary carriage (31,32) returned to the band inlet (4) again.
- the deflection rollers (42) are provided for the feed belt (5) and the deflection rollers (43) for the counter belt (6).
- the laying carriage (3) also has a guide roller (33) for the feed belt (5), which, after being deflected twice over the deflection rollers (34, 35) as well as further fixed deflection pulleys (42) and forming the feed belt (25) and the
- Feed line (26) back to the superstructure (2) is returned.
- the laying belt (6) is deflected by means of a deflection roller (36) and likewise returned to the superstructure (2) via deflection rollers (43) fixed to the frame.
- the Floraustritt (37) is formed between the pulleys (35,36).
- the guide belts (5,6) each have a laterally outwardly directed band portion (44,45), which is aligned substantially parallel to the car traveling direction and the discharge belt (8).
- the band sections (44, 45) each extend from the reciprocating deflection rollers (35, 36) to the adjacent stationary deflection rollers (42, 43). They can rest on the deposited fleece (23) at a small distance above or with a touch contact. They cover the fleece (23) in all laying carriage positions as a cover against air vortices and other disturbing environmental influences.
- the belt revolving speeds and the carriage carriage speed are in the range between the reversal points and possibly with the exception of those there
- a tensioning carriage or auxiliary carriage (31) is provided which is controlled in dependence on the movement of the upper carriage (2).
- a tensioning carriage or auxiliary carriage (32) is provided, which is controlled in dependence of the movement of the laying carriage (3).
- the movement of the tensioning carriage (31,32) is positively controlled by means of toothed belt.
- the two main cars (2,3) can be used to form a short
- FIGs 2 and 3 illustrate a first variant of the band inlet (4) of the batt layer (1) of Figure 1 in detail.
- Figures 4 and 5 show a second variant of the band inlet (4).
- the pile (7) in the guiding zone (27) is guided on both sides essentially only between straight sections of the laying belts (5, 6) and, if necessary, clamped. This applies both to the one zone area at the belt inlet (4) and to the other zone area (41) between the two main cars (2, 3).

- the inlet section (9) is that band area in which the band sections (10,11) between the inlet and outlet slots (12,19) in such close proximity, and they receive the pile (7) between him and cover him or lead him on both sides.
- the inlet slot (12) may have a fixed or an adjustable width, which may be adapted to the respective requirements of the pile material, if necessary. It may be slightly larger than the pile thickness, so that the loose pile (7) initially without compression or compression can be included. The width may alternatively be equal to or smaller than the edge thickness and, if appropriate, already lead to a clamping when the pile (7) enters the strip inlet (4).
- the band sections (10, 11) run essentially parallel in the inlet section (9). This can be strictly parallel.
- the spacing of the band sections (10, 11) may alternatively decrease over the run length.
- an inlet section (9) tapering in a funnel shape at an acute angle can be formed, in which the pile (7) is gradually compressed and clamped before it reaches the outlet slot (19) at the lower deflection (15, 17).
- the width of the inlet slot (12) should be set larger than the flange thickness. But it is also possible to clamp at a small slot width the pile (7) immediately upon entry into the band inlet (4) and to increase the compression over the length of the inlet section (9) even further.
- the choice of the suitable setting depends on the type of pile material and, if appropriate, also on the pile feed rate and / or other parameters.

- the two lower pulleys (15,17) are mutually and laterally distanced. Their distance on the connecting line of their axes (38,39) is significantly greater than the thickness of the pile (7) and the two bands (5,6).
- the inlet section (9) with the adjacent parallel guide of the band sections (10, 11) extends in both variants to the upper region of the deflection rollers (15, 17). It ends above the axes (38,39) at the beginning of the deflection of one of the bands (5,6).
- the band inlet (4) has a total of five deflection rollers (14,15,16,17,18).
- the florinde laying belt or feed belt (5) is guided over two preferably on the upper main car (2) relatively stationary deflection rollers (14,15).
- the deflection rollers (14,15) are in the two variants according to the slope of the inlet section (9) in height and laterally forward or distanced backwards.

- the height difference between the pulleys (14,16) can be considerable.
- the axis of rotation (46) of the deflection roller (16) lies above the uppermost circumferential point or zenith (47) of the deflection roller (14).
- the essentially straight band portion (11) of the opposite band (6) thereby extends at least to the zenith (47) and preferably beyond and forms a straight gusset or funnel wall.
- the inlet slot (12) can also be kept narrow or narrow. Both are favorable for trouble-free pile guide in the inlet and deflection, especially at high speeds.
- this arrangement is favorable for a gain of the first deflection and a reduction of the inclination angle ⁇ , ⁇ 'in favor of an increase of ß, ß. 1
- the side and height spacing of the deflection roller (16) to the deflection roller (14) of the flour guiding laying belt (5) is comparatively small, resulting in a short inlet funnel (12).
- the inlet section (9) is relatively long, the straight strip sections (10, 11) running closely over almost their entire length and without any great length offset.
- the slightly longer band section (11) protrudes slightly at both ends and approximately equidistant over the band section (10).
- the side and height spacing of the guide rollers (14,16) may be greater, the guide roller (16) at a considerable distance above the zenith (47) of the guide roller (14), resulting in a longer and further opening inlet funnel (12) leads.
- the band sections (10, 11) have a larger and asymmetrical length offset and form a shorter inlet section (9).
- Laying belt (6) a recurring belt loop (13) in which it is guided over the third deflection roller (18) and is deflected in the direction of the laying carriage (3) back.

- the deflection rollers (16,17,18) and the support roller (21) with suitable Delivery facilities (22) are changed in their position.
- the feed direction is preferably substantially perpendicular to the direction of the inlet section (9). This can reduce the width of the
- the bands (5,6) can be permeable to air, so that compressed by the increasing constriction of the inlet section (9) of the Flor and thereby the air is pressed out.
- the deflection roller (18) can be adjusted horizontally and can thereby be approximated or removed relative to the deflection roller (17) of the laying belt (6) for changing the belt loop (13).
- the support roller (21) is vertically adjustable and can thus also be approximated or removed relative to the deflection rollers (15,17).
- the pile guide (21) is influenced by the pile guide at the lower end of the outlet slot (19) and at the entry into the zone area (41) by the parallel guide belts (5, 6) following the deflection roller (15). Modifications of the embodiments shown are possible in various ways. In the variant of Figures 4 and 5, the upper guide roller (16) of the laying belt (6) may be located lower, resulting in a superstructure (2) results in lower overall height. The overall length can be shortened compared to the first variant of Figure 2 and 3. Further, the number of pulleys (14,15,16,17,18) and their orientation may vary.
- the deflection rollers (15, 17) can have a certain height offset.
