Definitions

  • the invention relates to a method and an apparatus for generating a nonwoven fabric by superimposing several bobbins.
  • carded webs are formed in multiple layers layered to a fleece.
  • Nonwoven webs with longitudinal orientation of the fibers are in some applications desired, for example, those in which the nonwoven web has a pronounced To have stretch strength in the longitudinal direction. If you want to make one Nonwoven laying used, the laying member in the transport direction of the delivery conveyor belt, on which the fibrous web is stored, moved back and forth and thereby a continuously fed fibrous web coherent in each other overlapping layers deposits, arise U-shaped reversing points from superimposed pile layers in the laid fleece, which are in a subsequent Solidification process, for example by needling, behave unfavorably and finally to transverse ribs in a product needled from the web express.
  • the invention is based on the object, a method and an embodiment thereof to specify suitable nonwoven layers with which nonwoven webs can be produced, their track properties are influenced in an excellent way by the laying process and possibly fibers orientated in one direction only contain.
  • the invention does not deposit the continuously fed pile discontinuously, but cuts out of it individual Flortafeln, which overlap in one shingled patterns are stored. In the storage of the Flortafeln more consistent Dimensions are aligned on one of the edges of the pile boards.
  • a card web fed transversely to the delivery conveyor belt is produced cut perpendicular to the longitudinal extent of the card web, in which case the Alignment takes place at one of the cut edges.
  • the cut-off blackboard is rectangular, which also includes a square shape.
  • the delivery conveyor is moved discontinuously, so that the exactly perpendicular to the formed Nonwoven web extending pile tray is not affected. After filing a single Flortafel is the delivery conveyor belt by a pitch moved, and then the next Flortafel is filed.
  • the overlap of the blackboards is chosen such that the pitch is one integer fraction of the dimension of the blackboard in the overlap direction, then it is ensured that at all points of the web the same number of pile layers lie one above the other. This gives a nonwoven uniform thickness.
  • the laying the Flortafeln on the delivery conveyor belt in the longitudinal direction of the fiber web opens the possibility in a particularly advantageous manner, the Cutting the Flortafeln of the fiber web not by cutting, but by locally overstretching the fiber web. It results in In this case, no sharp dividing lines, so no sharp transitions between the superimposed pile tracks within the laid web can train.
  • the separation by cutting can be done both in front of the laying organ within the Fleece layer or at the inlet, but also at the delivery gap of the laying body executed become.
  • the laying body already fed separated Flortafeln.
  • the Flortafel only after complete deposition on the web in formation from the fiber web cut off. This variant simplifies the control of the cutting process, because this synchronized with the reversal of the movement of the laying organ can be.
  • the laying member can deliver in both directions Flor and drop. But it is also possible, the laying organ only during one of the back and returning movements are active, i. Flor to let go. The may be required in some cases, for example, when the supplied pile is two-ply and the layers differ in their properties and therefore should not be overturned alternately.
  • two card webs for Forming the fleece are used, the originating from them Flores are alternately discarded.
  • the delivery zone of the non-wovens two laying organs active, which are virtually opposite each other and alternately lay pile in the delivery zone.
  • nonwoven webs to produce, matching in the longitudinal and transverse directions Have yield strengths.
  • this is the delivery zone the delivery conveyor belt assigned two laying organs, the delivery zone alternately transversely and longitudinally with respect to the longitudinal extension of the delivery conveyor belt provide them with a table-top. It is understood that to this Purpose laying organs of such type must be used, which in the retracted Condition make the delivery zone freely accessible to the respective other laying organ.
  • a delivery conveyor belt 1 is shown schematically in plan view, the a steep-arm leveler 2 is assigned, in addition to the longitudinal side of the delivery conveyor belt 1 is arranged.
  • the delivery conveyor belt 1 has a transport direction, which is marked with the arrow A.
  • the steep-arm leveler 2 is transverse to the transport direction A a card web 3 in the feed direction B supplied perpendicular to the transport direction A of the delivery conveyor belt 1 runs.
  • the steep-arm leveler 2 is by means of a stationary Axis 4 pivoting Zulitearms and hinged at the upper end devisrms 6 is able to deposit pile on the delivery conveyor 1.
  • Fig. 1 the orientation of the fibers contained in the fiber web 3 with shown thin, longitudinal lines. Accordingly, the fibers run in a produced on the delivery conveyor belt 1 nonwoven web 7 transverse to Longitudinal extent of the nonwoven web 7, which is due to corresponding thin lines in the Drawing is shown, provided that the delivery conveyor belt 1 during the laying movement of the devisrms 6 is not moved.
  • the invention therefore provides that of the fleece layer 2 on the delivery conveyor belt 1, the pile is not continuous, but filed in the form of table boards is, which are separated from the card web 3. This separation can be done by means of a cutting device, either in front of the nonwoven layer 2, disposed within the same or at the delivery gap of the web layer 2, in the Drawing is not shown.
  • Fig. 2 shows an embodiment of the invention, in which a nonwoven layer 2 with respect of the delivery conveyor belt 1 is arranged so that it is in the longitudinal direction Flortafeln of the delivery conveyor belt 1 deposits, so that a batt 7 is formed, in the fiber orientation runs in the longitudinal direction.
  • the dash-dotted in Fig. 2 Line c indicates the position of the layer conclusion of the laid by the fleece layer 2 Flortafel at.
  • the individual pile layers 3a are flaky one above the other. Their cut edges can be transverse or oblique to the delivery conveyor 1 run. Again, in Fig. 2, the cutting device is not shown.
  • FIG. 1 A variant which has already been briefly mentioned is shown in FIG.
  • two steep-arm levelers 2a and 2b associated with a pile 31 transversely to the transport direction A of the delivery conveyor belt 1 from direction B and another pile 32 in the transport direction Feed A from the delivery conveyor belt 1.
  • the fiber layers in the card webs 31st and 32 are again characterized by thin lines, they each run in Longitudinal direction of the fed fiber webs.
  • the two fleece layers 2a and 2b serve the delivery zone on the delivery conveyor belt 1 alternately.
  • the transverse feeding Nonwoven layer 2a has just retracted while the nonwoven layer operating in the longitudinal direction 2b is just extended.
  • the work result of the two nonwoven layers 2a and 2b shows in the form of a fleece band 7, in which both in the transverse direction and longitudinally extending fibers are present, which by intersecting thin lines in the nonwoven web 7 is symbolized.
