  • nonwoven web generally designates any web of fibers and / or filaments or superposition of webs of fibers and / or filaments, regardless of the method of manufacture. the sail or sails, and the type of fibers or filaments.
  • the nonwoven web may consist of a single web of fibers or filaments (monolayer nonwoven web) or of several superimposed webs of fibers or filaments (multilayer nonwoven web), or the sails being chosen from the list: nonwoven carded fleece, airlaid nonwoven fleece, meltblown nonwoven fleece, spun nonwoven fleece.
  • all the sails may be of the same type, or the nonwoven may be composite, that is to say composed of several sails of different types such as for example a composite nonwoven of type CMC (carded sail / sail “meltblown” / sail carded) or type SMS (sail “spun” / sail “meltblown” / sail “spun”)
  • nonwoven web Indifferently designates the veil or the superposition of veils of fibers and / or filaments before consolidation or after consolidation.
  • a belt conveyor comprising an endless conveyor belt which is wound on means rotary drive, roll type, the nonwoven web being in contact with the conveyor belt.
  • the conveyor belt is impermeable or breathable.
  • an endless conveyor belt is used that has a more or less complex path, with at least one portion of upward transport. This is the case, for example, for the conveyor belt which is used at the entrance of a crosslapper, such as that described for example in the international patent application. WO92 / 21799 .
  • the nonwoven web tends to slip under the effect of gravity relative to the conveyor belt.
  • This slip phenomenon is accentuated in the case of a smooth conveyor belt, and also increases with the angle of inclination and / or the weight of the nonwoven web.
  • the different superposed layers which are not linked together, also have a tendency to slide relative to each other, which is detrimental to the quality non-woven.
  • This slippage is also accentuated when the conveyor belt undergoes sudden changes in speed (acceleration and deceleration), which is the case for example for the conveyor belt input of certain types of spreader-lapper.
  • the European patent application EP 1 672 110 which is part of the state of the art under Article 54 (3) EPC, discloses ( figure 2 ) a method of transporting a nonwoven web by means of a conveyor belt having at least one upward transporting portion, during which the nonwoven web (WE) and / or the web is electrostatically charged conveying means (100) ascending so as to adhere the nonwoven web to the surface of the conveyor belt in said ascending transport portion (100a).
  • the present invention aims to propose a new technical solution to the aforementioned problem of sliding a nonwoven web in an upward transport portion and / or driven with a variable speed.
  • the solution of the invention is to electrostatically charge the nonwoven web and / or the conveyor belt, so as to adhere the nonwoven web against the surface of the conveyor belt. said upward transport portion and / or variable speed.
  • the invention thus has as its first object a method of transporting a nonwoven web by means of a conveyor belt comprising at least one transport portion which is ascending and / or which undergoes changes of speed.
  • the nonwoven web and / or the conveyor belt is electrostatically charged so as to adhere the nonwoven web to the surface of the conveyor belt in said upward transport portion and / or variable speed.
  • Another object of the invention is an assembly for transporting a nonwoven web, said assembly comprising a conveyor belt having at least one transport portion which is upward and / or which is subject to changes in speed.
  • said transport assembly comprises ionization means which, in operation, make it possible to electrostatically charge the nonwoven web and / or the transport belt, so as to adhere the nonwoven web to the surface of the conveyor belt in said ascending transport portion and / or variable speed.
  • Another object of the invention is a spreader-lapper which comprises as input a transport assembly mentioned above.
  • the nonwoven WE web may be of the monolayer type or the multilayer type, and is made of fibers and / or filaments forming a dielectric material. These are, for example, synthetic fibers or filaments based on polypropylene or polyethylene, and / or natural fibers or filaments of the cotton type, and / or artificial fibers or filaments of the viscose type.
  • This unconsolidated web WE web is for example manufactured upstream of the crosslapper 1 by a production machine (not shown) such as for example a nonwoven card, and is conveyed to the entrance E of the crosslapper 1 by any known means of transport, and for example by means of a T-belt conveyor which is shown only on the figure 2 .
  • crosslapper 1 The structure and operation of the crosslapper 1 are known to those skilled in the art and will therefore not be detailed in the present description. For the sake of simplification and conciseness, only Technical elements of the crosslapper 1 necessary for the understanding of the present invention will be described hereinafter. For a complete understanding of the structure and operation of the crosslapper 1, one skilled in the art can refer for example to the text of the international patent application WO 92/21799 .

  • the upper carriage 12 and the lower carriage 13 are movable in translation , and are equipped with drive means (not shown) for translating them in translation alternately in the two opposite directions D and G.
  • the belt conveyor 11 comprises a conveyor belt 110 which is wound along a closed path on guide rollers 111a to 111j, at least one of which is motorized for driving the conveyor belt 110.
  • 111a to 111d are usually embedded on the mobile carriage 12, and are mounted free to rotate about their central axis relative to the carriage 12.
  • the guide roller 111e is embedded on the carriage 13 and is rotatably mounted along its central axis with respect to this carriage 13.
  • the nonwoven web WE (produced upstream of the crosslapper for example by means of a not shown card) is deposited at the input E of the crosslapper 1 at the surface of the conveyor belt.
  • This web of WE fleece is conveyed by the conveyor belt 100 to a nipping zone of the nonwoven web between the two conveyor belts 100 and 110 (between the guide rolls 111). and 101j). Due to the synchronized back-and-forth movements of the carriages 12 and 13, the non-woven WE web is reciprocated back and forth in the opposite directions G and D, which allows the nonwoven web to be folded alternately. WE on itself at the surface of the conveyor belt 140 of the output conveyor 14.
  • This conveyor belt 140 is oriented transversely to the direction of entry (arrow F) of the nonwoven web WE and is movable in the direction of arrow K ( figure 1 ).

  • the position the height of the guide roller 101d is preferably adjustable, so that the value of this inclination angle A is adjustable. Also in some cases, the height position of the guide roller 101d is variable during operation, so that the value of this angle of inclination A varies during the movement of the conveyor belt. 100.
  • the crosslapper 1 of the invention is equipped with ionization means, which in the particular embodiment of the appended figures, are in the form of an ionizing bar 15.
  • the input conveyor belt 10 is made of an electrically conductive material (for example of metal) and acts as a mass connected to the earth.
  • the ionizing bar 15 allows, in operation, to generate a powerful electric field 15a, ion saturated, said ionizing field, and symbolized by dotted lines on the figure 2 .
  • the ionizing bar 15 comprises, for example, a plurality of electrodes or high-voltage tips which are fed by a high-voltage DC generator (not shown) and which make it possible to locally generate ions, for example negative ions.
  • the ionizing bar 15 is mounted above and close to the surface of the upward portion 100a of the conveyor belt 100, and extends transversely to the direction of travel F of the upward portion 100a of the conveyor belt 100.
  • the ionizing bar 15 is positioned in the vicinity of the guide roller 101 d, that is to say at the inlet of the upward portion, immediately downstream of the transition region between the upstream carrier T and the carrier of entry 10.
  • the ionization means 15 generate an ionizing field 15a which preferably extends over at least the entire width (L) of the nonwoven web WE.
  • the fibers and / or filaments of said nonwoven web WE are electrostatically charged, and are plated by their electrostatic charge against the surface of the conveyor belt in the ascending portion 100a.
  • the nonwoven web WE thus adheres strongly to the surface of the conveyor belt 100 in its ascending portion 100a.
  • This electrostatic retention of the nonwoven web WE advantageously avoids the slip phenomena of the nonwoven web WE in this upward transport portion 100a. It is thus possible, in particular, to transport the nonwoven web WE in the upward portion 100a with higher speeds and / or to transport heavier WE webs and / or to increase the angle of inclination.
