Definitions

  • the invention relates to a nonwoven layer, which in particular is suitable for large laying widths, with the features in Preamble of the main claim.
  • Such a fleece layer is known from EP-A-0 517 563 and EP-A-0 522 893 known. It has two main cars and two auxiliary or tension wagons with two endless revolutions and conveyor belts guided over the main and auxiliary wagons and a discharge belt. Move the auxiliary or tension wagons one below the discharge belt retracted divider partitioned area. When a such fleece layer used for larger widths problems with tape guidance in the area the auxiliary or tension wagons result.
  • US-A-4,830,351 shows another nonwoven layer with two Main carriage and a tensioning carriage for only one conveyor belt, the one between the upper main carriage and the frame is arranged.
  • a support carriage is assigned to at least one tensioning carriage. This supports the loop length extended by the tensioning carriage and prevents the strap from sagging. This is particularly advantageous for those tension wagons that are in drive connection with the lower main wagon and that move over a distance that corresponds to the full laying width. Accordingly, the maximum length of the belt loop pulled out by the tensioning carriage can correspond to the full laying width or even be greater.
  • the support carriage is preferably in drive connection with the upper main carriage and moves through it moves in the same direction with the associated tension carriage but only at half speed and above half way. In this way, the Support car always in the middle of the tension car extended strap loop and ensures a continuous and even center support.
  • the fleece layer can have several tensioning carriages, which are at in the same direction as a non-woven layer move.
  • tension wagons there are the belt loops pulled out by the tension wagons in different heights.
  • the tension wagons can side by side with a lateral distance on a common Carriage guidance be stored.
  • the tension carriage mounting is but separate from the main carriage storage different car routes. This simplifies to one the construction effort and the other ensures one Unbundling of driving movements. This is mostly from Advantage if there are other support cars, which are also stored on the carriage guides.
  • FIG. 1 shows a fleece layer (1) in the form of a so-called fleece tape layer, which from a card single-layer pile (3) fed via a feed belt (4) with two revolving endless conveyor belts (7,8) and on a transversely extending discharge belt (5) a multi-layer fleece and in the form of scales stores.
  • the arrows (33) indicate the direction of conveyance of the pile (3).
  • the fleece layer (1) shown corresponds in its Basic design and non-woven layers known in its kinematics according to EP 0 517 563 or WO 97/19209.
  • the fleece layer (1) has two main carriages (10, 11), which are Move back and forth over the discharge belt (5).
  • the embodiment shown is a co-rotating fleece layer (1), in which the main carriage (10,11) always drive in the same direction.
  • the Upper carriage (10) moves with half Speed compared to the lower laying carriage (11) and also places half the distance between the reversal points back.
  • the two conveyor belts (7,8) are movable Deflection rollers (36) on the two main carriages (10, 11) and via stationary deflection rollers (37) in the frame (2) of the Fleece layer (1) in movable loops.
  • the supplied single-ply pile (3) is first on one Conveyor belt (7) open up to a belt inlet (9) on Superstructure (10) transported where the second conveyor belt (8) come in addition.
  • the tape inlet (9) can be an open one or closed belt inlet.
  • the two conveyor belts (7,8) meet at the belt inlet (9) together and take the pile (3) between them. she then extend together from the superstructure (10) to Laying carriage (11), which the pile (3) in one over the Discharge belt (5) reciprocating movement with one Laying width (6).
  • the fleece layer (1) also has two tensioning carriages (14, 15) on the loop length of the conveyor belts (7,8) in keep essentially constant and the following for it ensure that the pile (3) in the edge areas of the fleece (32) is deposited essentially without edge thickening.
  • the tension wagons are (14,15) not shown in Figure 1.
  • the conveyor belts (7, 8) reappear on the laying carriage (11) apart and extend in on both sides lower horizontal conveyor belt runs (26, 27) across and parallel over the deposited fleece (32) and the discharge belt (5). They act as a cover and can also be opened rest on the fleece (32).
  • Figures 2 and 3 show the two end positions of the Carriage movements, the laying carriage (11) in FIG. 2 on the right edge of the discharge belt (5) or the Laying width (6) and in figure (3) on the left edge.
  • those on the superstructure (10) converging conveyor belts (7,8) from the belt inlet (9) in a substantially horizontal band section directly led to the laying car (11).
  • it can also be an opposing layer, in which the two main carriages (10, 11) are always in move in opposite directions.
  • an opposing layer in which the two main carriages (10, 11) are always in move in opposite directions.
  • Such a design is e.g. known from EP 0 315 930.
  • the two parallel conveyor belts are relaxed (7,8) between superstructure (10) and laying car (11) over a stationary deflection roller arrangement (37) in the frame (2) guided.
  • the fleece layer (1) shown can be a so-called Paper felt storage, which is for particularly large laying widths (6) is suitable. At least there is support for this the lower conveyor belt dreams (26,27) advantageous. A Such support can also be found in nonwoven layers successfully used with a smaller laying width.
  • the Support consists of at least one auxiliary car (12, 13), which can be moved back and forth over the discharge belt (5) is stored.
  • each is lower Conveyor belt run (26, 27) your own auxiliary car or Support carriage (12,13) provided.
  • the one for a conveyor belt (7) provided support carriage (12) moves between the Laying carriage (11) and the neighboring frame (2) back and forth ago.
  • the other support carriage (13) is connected to the superstructure (10) rigidly connected and preferably integrated into this.
  • FIG. 4 shows this Arrangement.
  • One support carriage (12) is freely movable stored and is in a drive connection (28) the superstructure (10).
  • the drive connection (28) is off Figure 5 can be seen.
  • Figure 4 shows the same Carriage position the guidance of the conveyor belts (7,8).
  • the coupled support carriage (13) is at a lower approach (25) of the superstructure (10) arranged. Due to its structural Integration does not have its own castors (34).
  • the rigid coupling or the drive connection (28), e.g. from a castor-fixed castors rotating cable drive can exist, the move two support carriages (12, 13) synchronized with the superstructure (10) with the same direction and speed.
  • the coupled support car (13) independently movable on the Carriage guide (18) or other suitable location be stored. He is then through with the uppercarriage (10) rigidly connected to a rod or the like.
  • Figures 2 and 3 illustrate the positions of the support car (12,13). If the laying carriage (11) is in a narrow position Neighborhood to the uppercarriage (10) on the right edge of the Laying width (6), the free support carriage (12) a position in about half of the width, in which he the long spread conveyor belt strand (26) between Laying carriage (11) and the left frame (2) approximately in the middle supported. Figure 2 shows this arrangement. In the other The laying carriage is in the extreme position according to FIG (11) and the support carriage (12) side by side on the other edge the laying width (6). The superstructure (10) with its The tensioning carriage (13) then takes a position approximately in the middle Insert width (6) and then support it after the right side spread out lower conveyor belt strand (27) between the laying carriage (11) and the right frame (2).
